Replaces / Cross-Reference Part Numbers
This capacitor replaces any round or oval dual run capacitor with matching 45+5 uF capacitance and 370V or 440V specifications. It serves as a universal replacement for a wide range of part numbers from various manufacturers.
Compatibility & Fitment
Designed for heavy-duty, continuous use in HVAC systems such as central air conditioners and heat pumps. This dual run capacitor powers a compressor motor (HERM terminal) and a fan motor (FAN terminal) simultaneously from a single common line (C terminal). It is compatible with units requiring the specified capacitance and voltage.
When to Replace
A failing capacitor can cause damage to motors. Consider replacement if you observe the following symptoms:
- Compressor or fan motor struggles or fails to start.
- AC unit hums but does not activate.
- Fan spins slowly or not at all.
- Visible signs of damage, such as a bulging or leaking capacitor case.
- Measured capacitance is outside the rated tolerance (e.g., not within ±6% of 45/5 uF).
Installation Tips
- Warning: Capacitors can store a lethal electrical charge even when power is off.
- Disconnect all electrical power to the HVAC unit at the main breaker panel before proceeding.
- Safely discharge the old capacitor by carefully shorting across the terminals with an insulated-handle screwdriver.
- Confirm the uF and VAC ratings of the replacement match the original component.
- Note the wire placement on the C, FAN, and HERM terminals before disconnecting.
- Ensure all new connections are secure. Professional installation by a qualified technician is recommended.

Great quality tux for the price
Color: White, Size: XX-Large, Color: White, Size: XX-Large
I was pleasantly surprised with the quality and fit right out of the package. The cloth has a subtle pattern that gives it an upscale look without being flashy, and overall it feels far nicer than I expected at this price.
Jacket:
The jacket has a good weight and thickness, so it feels solid and well-made. Sleeve length was perfect right out of the box, which almost never happens for me. The only fit issue was a bit of snugness in the chest and underarm area, but I have broad shoulders and a larger chest, so that’s not unusual. My dress shirt sleeve length is 36.5", so I went with an XXL instead of my usual XL to make sure the sleeves were long enough. That was the right call, because it’s always easier for a tailor to size something down than to try and make something too small work. Aside from a quick tweak in the chest, this could easily be worn straight out of the package.
Pants:
The pants are noticeably thinner than the jacket and you can kind of see through them, so you’ll want to be mindful when choosing undergarments. That said, the lighter fabric is actually a plus for summer outdoor events or warm indoor venues since it will help keep you cool and comfortable. The flexible waistband made them very comfortable, and the fit in both the waist and length was spot on. For reference, I usually wear 38x32 dress pants and these matched perfectly.
Overall:
The quality is excellent for the cost. Even with a minor tailoring bill, my total cost to own this tux will still be less than renting one for a single event. I couldn’t be happier with the purchase and wouldn’t hesitate to pick up another.

brings me to today’s formal fashion
Color: Brown, Size: X-Large
the peak lapel made me feel sharp for the big family dinner. the slim fit worried me, but it was surprisingly comfy, not too tight on my retired belly. the pockets are deep, which is great for my reading glasses case. didn't need much ironing, just hung it up. a solid, non-fussy suit for us old guys.

Works for Dress-Up, Not for Formal Events
Color: Brown, Size: Medium, Color: Brown, Size: Medium
This brown tuxedo is about what you’d expect for under $100 on Amazon. The fabric has a pretty brocade pattern but it’s very thin and floppy. The jacket is lined, which helps give it some structure and makes it look a lot nicer, but the pants don’t lay well since they’re unlined and lack structure. The brown color is actually really nice—rich without looking too chocolately, almost leaning burgundy. That said, the fit on both the jacket and pants is surprisingly good. Overall, this is a fun tux for a costume party or one-off dress-up event, but not something you’d want to rely on for a wedding or a truly formal occasion. Just keep your expectations aligned with the price.

A true beauty
Color: Red, Size: Large
This tuxedo set is so beautiful. The red is extremely striking and is sure to grab everyone's attention. I ordered a size L, as I am on the cusp of Medium and Large. The pants fit very well, and they have some adjustment points around the waist in case they need to be let out a little more. Also, in the waist band is some elastic portions, which make finding the perfect fit something you won't have to think much about.--- they will stretch with you. The jacket feels like it is custom fitted by a tailor. The quality of this tuxedo, considering the price point, is exceptional.
