7 Best DeWalt Air Compressor Capacitors (November 2026)
The best DeWalt air compressor capacitors include the Yancheng Yatai YATAI CBB60 Capacitor 80uF 300V AC for 80uF motor ratings, the Sealed Unit Parts Co. for hard-start kits, and the YWBL-WH CBB60 Run Capacitor for 120uF run ratings.
On this page (5 sections)
The best DeWalt air compressor capacitor for most compatible motors is the Yancheng Yatai YATAI CBB60 80uF capacitor, with 80uF capacitance, 300V AC, 2 wires and a 1.73 x 3.74 in cylindrical body.
That top pick only fits when the original part and motor label call for those same values. Match capacitance, voltage, dimensions and connection style before you order.
A DeWalt compressor capacitor is not selected by brand name alone. The motor rating matters more than the compressor label.
That is why a 40uF, 80uF, 120uF or 216-259uF replacement only makes sense when it matches the old part. Two motors in the same compressor family can use different values.
Note whether the original uses wire leads, terminals, inserts or a snap-in or panel mount. That detail can rule out an otherwise close option.
Physical space also matters in a compact compressor housing where wiring and guards sit close to the motor. Measure the old body and the open space around it, then compare those numbers with the replacement listing.
A capacitor that is too long or too wide may not sit securely even when the electrical values are correct.
Care starts before fitting because an old capacitor can hold stored charge after power is removed. Disconnect power and follow safe discharge and handling steps before touching the terminals.
Keep the replacement in a dry place and check the wires and body for damage before use. If the rating is unclear, a qualified technician can identify the correct part more safely than guesswork.
If you are checking a weak starting motor, follow our guide to how to check an air compressor capacitor. Photograph the wiring before anything is disconnected.
For general starting-capacitor options, compare our Best Air Compressor Start Capacitor guide. That guide does not replace the exact rating on your DeWalt motor.
Think of the choice as a matching exercise rather than an upgrade. The right capacitor has the correct uF, suitable voltage, workable size and the same kind of connection.
When those details line up, the replacement is easier to fit and keep in place during daily use. When they do not, pause and recheck the original label instead of forcing a substitute.

The best DeWalt air compressor capacitors by motor rating
The best match depends on the original capacitor's uF value, voltage and physical layout. We compared those details first, then considered wire leads, mounting style, body dimensions and whether each option is a run capacitor or a motor-start kit.
Our score weighs specs, features and buyer feedback against what you're shopping for. Product scores are not a substitute for the electrical information printed on your DeWalt compressor or its original capacitor.
Yancheng Yatai YATAI CBB60 Capacitor 80uF 300V AC: Best for 80uF motor ratings
- 80uF capacitance
- 300V AC
- 2-wire connection
- 1.73 x 3.74 in cylindrical body
This Yancheng Yatai capacitor matches a DeWalt compressor motor that calls for 80uF and up to 300V AC. Its 2-wire design and cylindrical body make the original wiring and available space important checks.
Pros
- 80uF rating
- 300V AC rating
- 2-wire design
Cons
- Only suitable when the original ratings match
- Cylindrical dimensions need checking
The Yancheng Yatai YATAI CBB60 is the strongest general pick when your DeWalt motor calls for 80uF and 300V AC.
Its 2-wire setup is straightforward to compare with an existing wire-lead capacitor.
Still, the terminals and wire positions need to match the compressor wiring before fitting.
The cylindrical body measures 1.73 x 3.74 in, so measure the compartment before ordering.
That compact round shape can suit many standard enclosures, yet it still needs room to sit without pressure on the wires.
Its round housing uses flame-retardant plastic.
The product data identifies metallized polypropylene film as the capacitor material.
The 50/60Hz rating covers common AC motor frequencies.
Yancheng Yatai describes this capacitor for blower motors, air compressors, HVAC systems and other AC motor uses.
For a DeWalt compressor, those listed uses are background only.
The motor label and old capacitor remain the deciding evidence.
Choose this one when the old DeWalt capacitor shows an 80uF rating and the voltage requirement is compatible.
Do not use the 80uF value as a substitute for a motor marked 40uF, 120uF or a higher start-capacitance range.
A different uF rating changes the electrical match even when the body looks similar.
Check the snap-in mounting and wire reach as a final step.
If the space and connections line up, this is the cleanest option in the group for 80uF motors.
Sealed Unit Parts Co.: Best for hard-start kits
- Relay/capacitor hard-start kit
- Designed for PSC single-phase systems
- Increased compressor starting torque
- 3.5 x 1.75 in body
This Sealed Unit Parts Co. option is a relay/capacitor hard-start kit rather than a simple replacement run capacitor. It fits a different repair path when a compatible PSC single-phase compressor system needs a hard-start kit.
Pros
- Relay and capacitor in one kit
- Designed for PSC systems
- Compact body
Cons
- Not a direct match for every DeWalt compressor
- Electrical compatibility must be confirmed
The Sealed Unit Parts Co. option is a relay/capacitor hard-start kit, so it belongs in a different category from the simple CBB60 replacements. It is designed for permanent split capacitor single-phase air-conditioning and heat-pump systems.
The kit is described as increasing compressor starting torque, with a body size of 3.5 x 1.75 in. That may make it useful for a compatible DeWalt motor or compressor system that needs a hard-start kit rather than a replacement run capacitor.
Check the compressor's wiring plan before choosing this option. Its product data does not give a standard 40uF, 80uF or 120uF replacement rating, so it should not be treated as a universal capacitor swap.
Choose it when your repair calls for a relay and capacitor hard-start kit. If you need a normal replacement capacitor, compare the other picks by the exact uF and voltage printed on your old part.
YWBL-WH CBB60 Run Capacitor: Best for 120uF run ratings
- 120uF capacitance
- 250V AC
- ±5% tolerance
- 50/60Hz operation
The YWBL-WH CBB60 run capacitor suits a compatible DeWalt motor marked for 120uF and 250V AC. Its 50/60Hz rating and panel-mount format make the original motor label and mounting space key checks.
Pros
- 120uF rating
- 250V AC
- ±5% tolerance
Cons
- Panel-mount format may not match the original
- 120uF is not interchangeable with 80uF
The YWBL-WH CBB60 is a good fit for a DeWalt compressor motor that calls for 120uF at 250V AC.
It has a ±5% capacitance tolerance and is rated for 50/60Hz operation.
The tolerance means the value should stay close to the printed 120uF rating in normal use.
That matters when the motor expects a precise run capacitor value rather than a rough estimate.
Its product data identifies a panel-mount format and a plastic shell.
The upper temperature rating is 70°C.
That gives you another detail to compare with the original part and the compressor's operating environment.
A warm compartment with limited airflow can make heat ratings more relevant in daily use.
The 120uF value is the main reason to consider it.
It is not an upgrade for an 80uF motor.
Its panel-mount format may not fit a compressor that uses a snap-in body or wire leads.
That trade-off is easy to miss if size is checked but mounting is not.
Choose this pick when the original DeWalt capacitor shows 120uF and 250V AC, and the mounting space supports the panel format.
For a wire-lead 120uF replacement, compare the BOJACK option below.
Look at the terminal position before ordering, since panel connections are not interchangeable with loose leads.
When the mount matches, the YWBL-WH gives a tidy option for 120uF run circuits.
BOJACK Run Capacitor 120 uF 250V AC: Best for 120uF wire leads
- 120uF capacitance
- 250V AC
- 2 wire leads
- 1.97 x 4.06 in cylinder
This BOJACK capacitor gives a compatible 120uF DeWalt compressor motor a 250V AC, 2-wire replacement option. Its 1.97 x 4.06 in cylindrical size may help when the original uses a similar wire-lead layout.
Pros
- 120uF ±5% rating
- 2 wire leads
- Published body dimensions
Cons
- Longer body than some alternatives
- Only fits motors calling for 120uF
The BOJACK 120uF run capacitor is the best wire-lead choice for a compatible DeWalt compressor motor marked 120uF and 250V AC.
It has a ±5% tolerance and a 2-wire connection.
Those two wires make it easier to compare with an original capacitor that also uses leads.
The cylindrical body measures 1.97 x 4.06 in, with a stated cable length of 22cm.
Those measurements help you compare the replacement with the old capacitor and the space around the motor.
The lead length can be helpful where terminals sit away from the body.
It can also be a problem if extra cable has to be tucked into a crowded housing.
BOJACK describes it for AC unidirectional motors, refrigerators, air conditioners and air compressors.
The product data also identifies a 50/60Hz rating and a snap-in mount.
That combination of leads and snap-in mounting gives more than one way to secure the part.
Check which method your compressor bracket actually supports.
Choose it when the uF and voltage match and you need wire leads.
Check the body length before ordering because a longer cylinder can interfere with the compressor housing or nearby wiring.
A small difference in height can matter under a cover or beside a guard.
When the fit is confirmed, this is a practical 120uF choice for wire-lead layouts.
Seentech 216-259 uf/MFD 220-250 VAC ±20% CD60: Best for high-start-capacitance needs
- 216-259uF range
- 220-250V AC
- ±20% tolerance
- 10,000 AFC anti-explosion pressure switch
The Seentech CD60 is for a DeWalt compressor motor that specifically calls for a 216-259uF motor-start capacitor in the 220-250V range. Its broad capacitance range is not a reason to substitute it for a lower-rated capacitor.
Pros
- High motor-start capacitance range
- 220-250V range
- Anti-explosion pressure switch
Cons
- ±20% tolerance
- Not a substitute for common 80uF or 120uF ratings
The Seentech CD60 is the right type of option for a motor-start circuit that specifically calls for 216-259uF at 220-250V AC.
Its capacitance range is much higher than the 40uF, 80uF and 120uF picks in this guide.
That gap is exactly why it should not be treated as a stronger version of those parts.
This round capacitor has a ±20% tolerance and a stated operating range from -40°C to +65°C.
The wider tolerance also means the actual value can vary more than with a ±5% run capacitor.
The product data identifies a 10,000 AFC anti-explosion pressure switch and a through-hole mounting style.
Through-hole mounting needs the correct bracket and spacing in the compressor housing.
Do not choose it because a higher uF number seems stronger.
A compressor motor needs the capacitor value specified for its start circuit.
This CD60 is not a general replacement for a lower-rated DeWalt capacitor.
Using it in the wrong circuit could create a mismatch between the motor and the part.
Choose it only after confirming the original motor-start rating.
Its 220-250V range, round body and through-hole mount also need to fit the compressor's wiring and bracket.
That makes it a specialist pick for a clear CD60 application.
For most DeWalt run capacitor swaps, the lower uF CBB60 options will be the better starting point.
uxcell CBB60 Run Capacitor 40uF AC Double: Best for 40uF and 450V ratings
- 40uF capacitance
- 450V AC
- ±5% tolerance
- 3.7 x 1.8 in body
The uxcell CBB60 option fits a compatible DeWalt compressor motor marked for 40uF and 450V AC. Its double-insert cylindrical format and 94 x 45mm body require a close comparison with the old capacitor.
Pros
- 40uF rating
- 450V AC rating
- ±5% tolerance
Cons
- Not suitable for 80uF or 120uF motors
- Double-insert design needs terminal matching
The uxcell CBB60 is the best fit in this group for a DeWalt compressor motor that calls for 40uF at 450V AC.
It has a ±5% tolerance and a 94 x 45mm body, listed as about 3.7 x 1.8 in.
That size is compact enough for many motor compartments, but it still needs a direct comparison with the old body.
This is a double-insert cylinder for a single-phase AC motor.
The double-insert layout means the connection points are part of the fit, not an afterthought.
The product data describes it for air compressors, water pumps, pressure washers, air conditioners, motors and other equipment.
Those broad uses do not change the need to match your specific DeWalt motor.
The 450V AC rating is higher than several other options here.
That higher voltage does not make it suitable for a motor with a different capacitance requirement.
The 40uF value must match the compressor's original specification.
Matching capacitance first keeps the choice focused on the motor's needs.
Choose it when the old DeWalt capacitor is marked 40uF and the double-insert layout fits.
Measure the body and terminal position before ordering.
Check that the inserts line up with the existing leads or terminals.
When those details match, the uxcell is a clear option for 40uF and 450V AC motors.
BOJACK CBB60 120 uF mfd ±5% 250v: Best for snap-in 120uF mounting
- 120uF capacitance
- 250V AC
- ±5% tolerance
- Snap-in mount with adjusting screw
This BOJACK CBB60 capacitor is another 120uF, 250V AC option, with a snap-in mount and bottom adjusting screw. Choose it only when the DeWalt compressor's original mounting method and available height allow it.
Pros
- 120uF ±5% rating
- Snap-in mount
- 50/60Hz rating
Cons
- Tallest body in this group
- No wire leads listed in the product data
The BOJACK CBB60 is another 120uF, 250V AC choice, with a snap-in mount and a bottom adjusting screw.
Its ±5% tolerance and 50/60Hz rating suit a compatible motor with those same requirements.
The adjusting screw can help secure the body where a snap-in bracket is used.
That is a useful detail for a compressor housing that relies on mounting rather than loose leads.
Its body measures 1.9 x 4.84 in, making it the tallest option in this group.
Check the available height around the DeWalt compressor motor before ordering.
Take extra care if the original capacitor sits under a cover or beside a guard.
A taller body may look fine on paper yet leave little room for wiring above it.
BOJACK describes this capacitor for AC motor run applications, direct-cooling systems, heat pumps, pool pumps and air conditioners.
Those uses do not remove the need to match the compressor's own electrical rating.
The product data does not list wire leads for this model.
That makes the terminal and bracket layout more important than with the wire-lead BOJACK option.
Choose this pick when the original capacitor is 120uF and 250V AC, and a tall snap-in body works in the compartment.
For a shorter 120uF option, compare the YWBL-WH or BOJACK wire-lead model.
Height is the main trade-off here, so measure twice before you commit.
How to match a capacitor to a DeWalt compressor motor
Match capacitance first, then confirm voltage, physical size, connection style and mounting method. The capacitor's uF value is not a detail to estimate from the compressor's horsepower or from another DeWalt model.
Read the printed information on the old capacitor. Look for uF or MFD, voltage, frequency, terminal or wire layout and any part number.
Take a photo before disconnecting wires so you can compare the connection positions during reassembly.
Voltage also matters. A replacement should have a suitable voltage rating for the motor circuit, but a higher number does not make an otherwise incorrect capacitor safe or compatible.
Next, measure the body and inspect the mount. The products here include wire-lead, panel-mount, snap-in, through-hole and double-insert designs.
A capacitor with the right uF value can still fail to fit the bracket or reach the wires.
For another brand comparison, see our guide to the best Craftsman air compressor capacitor. The matching process is the same: identify the motor's electrical values before comparing product shapes.
Start capacitor or run capacitor: which one does a DeWalt compressor need?
A start capacitor helps a motor begin turning, while a run capacitor supports the motor during operation. That basic split is a good first check when a DeWalt compressor is running poorly.
For another brand, compare Ingersoll Rand start capacitors. The exact circuit depends on the compressor motor, so the old part and the wiring diagram should guide the choice.
A run capacitor stays in the circuit for ongoing motor support. A start capacitor is tied to the starting portion of the circuit.
Those roles can lead to different capacitance ranges and different expectations for the part. The Sealed Unit Parts Co. option is a relay/capacitor hard-start kit, which is another category rather than a simple one-for-one capacitor swap.
The CBB60 products are described as run capacitors or motor capacitors, while the Seentech CD60 is a motor-start capacitor. Do not replace a start capacitor with a run capacitor simply because the body looks similar.
The capacitance range, voltage and duty in the circuit can differ. A similar cylinder shape does not prove that two parts do the same job or that their electrical values are interchangeable.
For home and shop use, match the original part number and printed values first. Then confirm the connection style and physical size before ordering a replacement.
Our guide to how to change a capacitor on an air compressor covers the repair workflow. Disconnect power, release stored electrical energy safely and use the compressor wiring information before touching the terminals.
A photo of the wiring before removal can help during reassembly. Keep the new part dry and handle it without forcing the leads or terminals into place.
If the motor still behaves badly after the correct part is fitted, stop and have the circuit checked. That is more useful than swapping in a different type of capacitor and hoping for a change.
What should you check before ordering?
Check these 5 details against the original capacitor:
- Capacitance: Match the uF or MFD value required by the motor.
- Voltage: Confirm the AC voltage rating.
- Type: Identify run, start or relay/capacitor hard-start use.
- Connection: Compare wire leads, terminals, inserts or panel connections.
- Size and mount: Measure the body and check the bracket or available space.
Capacitance should be the first filter. A part with the wrong uF value is not a good substitute, even if it is smaller or cheaper.
Voltage comes next and should suit the motor circuit rather than be chosen at random. A higher voltage rating alone does not fix a wrong capacitance or wrong type.
Next, confirm whether the circuit needs a run capacitor, a start capacitor or a relay and capacitor hard-start kit. That distinction can change the whole repair path.
Connection style is easy to overlook during a quick online search. Wire leads, inserts, panel connections and snap-in bodies all need space and access in the housing.
Measure the old capacitor with care, including height where a cover or guard sits above it. A longer or wider replacement may not secure properly or may press against nearby parts.
A product name that includes "air compressor" does not guarantee a fit for your DeWalt model. The motor printed rating and the original capacitor layout are more useful than the brand name alone.
Photograph the wiring before disconnecting anything so the new part can be compared during fitting. Keep the work area dry and leave the replacement in its packaging until you are ready to fit it.
If you are unsure, ask a qualified technician to identify the part. Capacitors can retain dangerous electrical energy after the compressor is unplugged.
Spending a few minutes on these checks can prevent a return and a second repair attempt. Check capacitance first, then voltage, type, connection, size and mount before you order.
Verdict: which DeWalt air compressor capacitor should you choose?
Choose the Yancheng Yatai YATAI CBB60 if your DeWalt compressor motor calls for 80uF and 300V AC.
Its 2-wire cylindrical design makes it the top general pick for that rating.
Choose the YWBL-WH or either BOJACK 120uF option when the original rating is 120uF, then select by mounting style and available space.
That choice comes down to panel mount, wire leads or snap-in fit.
Choose uxcell for a compatible 40uF, 450V AC motor.
Its double-insert layout needs a close check against the original terminals.
Choose Seentech only for a motor-start circuit that calls for 216-259uF.
That CD60 option belongs in a high start-capacitance application, not a general run capacitor swap.
Choose Sealed Unit Parts Co. when the repair specifically needs a compatible relay/capacitor hard-start kit.
That kit should not be ordered as a simple replacement for a standard CBB60 part.
The best DeWalt air compressor capacitor is the exact electrical and physical match, not simply the highest voltage or capacitance.
Confirm the old part before ordering, then use safe procedures when changing it.
Match uF first, then voltage, type, connection, size and mount.
That order helps you rule out wrong parts quickly.
It also helps you compare several correct-looking options with less guesswork.
For daily use, a secure fit matters as much as the printed rating.
The capacitor should sit without strain on its wires or terminals.
It should also clear nearby housing parts and guards.
Keep the replacement dry and inspect it before fitting.
If the label on the old part is unreadable, get help identifying it before placing an order.
That step is safer than choosing a higher uF value and hoping the motor will accept it.
In short, let the original motor rating make the decision.

Frequently asked questions
What is the best DeWalt air compressor capacitor?
The best DeWalt air compressor capacitor is the one that matches the original motor's capacitance, voltage, physical size and connection style. The Yancheng Yatai YATAI CBB60 is the top pick here for a compatible 80uF, 300V AC motor.
A 120uF or 40uF capacitor is not an interchangeable substitute.
How do I match a capacitor to a DeWalt air compressor?
Read the capacitance and voltage printed on the old capacitor or motor information, then compare the replacement's dimensions, terminals, wires and mounting method. Match the original value instead of choosing a higher or lower uF rating.
Disconnect power and discharge the capacitor before handling it.
Can I use a 120uF capacitor instead of an 80uF capacitor?
No, not unless the compressor motor documentation specifically allows that value. An 80uF capacitor and a 120uF capacitor have different electrical ratings.
Choose the same capacitance and an equal or suitable voltage rating confirmed for your motor.
Are DeWalt compressor capacitors polarized?
The CBB60 capacitors in this guide are described as non-polarized AC capacitors, so they do not use positive and negative poles like a battery. The wires and terminals still need to return to the correct motor connections.
Follow the compressor's wiring diagram and use safe electrical procedures.
