Round run capacitor can be used to substitute Oval shape one with the same MFD and volt specs.A 450 volt capacitor can be used in place of a 370 volt, as it is build better, but the 370 can’t be used in place of a 450 volt. Review: Replacement for my dehumidifier; works great! - It is a bit bigger than the capacitor in my dehumidifier, but I was able to make it work with a few cuts to the dehumidifier’s plastic housing. It was a fairly easy replacement while following a couple YouTube videos and was my first time replacing a capacitor, so you can definitely figure it out too. The dehumidifier runs great now! Review: Will purchase from this seller again - I recently purchased the BOJACK 50 uF ±5% 50 MFD 370/450 V CBB65 Round Run Start Capacitor for my air conditioning unit, even though I ordered the wrong one by mistake, and I couldn’t be more satisfied with its looks ! This capacitor is a fantastic replacement part for AC motors, fans, or heat pump systems, and it’s been a game-changer in getting my unit back to peak efficiency. The build quality is impressive—sturdy, well-designed, and clearly made to withstand the demands of continuous operation. Installation was straightforward, thanks to its standard round shape and clear labeling, which made it easy to integrate into my system. Since installing it, my AC has been running smoothly, with no issues in starting or maintaining consistent cooling. The dual 370/450 V rating offers great versatility, making it compatible with a wide range of systems, which is a huge plus. What really stands out is the reliability. The ±5% tolerance ensures stable performance, and I’ve noticed improved efficiency in my unit’s operation, which has been a relief during hot summer days. For the price, this capacitor delivers exceptional value, offering OEM-level quality without breaking the bank. If you’re looking for a dependable, high-quality capacitor for your AC, fan, or heat pump, I highly recommend the BOJACK 50 uF CBB65. It’s a solid investment that gets the job done right! I returned this item as I ordered the wrong size and have the right one on the way. Shipping was really fast and the ordering process was easy. The packaging was really well structured keeping the capacitor safe during transit. ## Features - BOJACK 50 uf MFD 370 V/450 VAC Round Run Start Capacitor - Operating Temperature Range -40 ℃ to +70 ℃/ -104℉ to +158℉ - This Capacitor Will Run Compressor And Fan Motor - Engineered For Safety 10 000 AFC Anti Explosion Pressure Switch - Industrial Grade Replacement for Central Air-Conditioners, Heat Pumps, Condenser Fan Motors, and Compressors.It is small in size, lightweight, heat resisting and anti-explosion. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07VMH1213 | | Brand | BOJACK | | Capacitance | 50 Microfarad | | Capacitance Tolerance | 5 | | Capacitance tolerance | 5 | | Customer Reviews | 4.6 out of 5 stars 531 Reviews | | Item Shape | Round | | Manufacturer | BOJACK | | Manufacturer Part Number | BJ-CAP | | Material | Aluminium , Polypropylene | | Maximum Voltage | 450 Volts | | Model Number | BJ-CAP | | Mounting Type | Panel Mount | | Operating Voltage | 450 Volts | | Operating voltage | 450 Volts | | Shape | Round | | UPC | 768894139441 | ## Product Details - **Brand:** BOJACK - **Capacitance:** 50 Microfarad - **Material:** Aluminium, Polypropylene - **Operating voltage:** 450 Volts - **Shape:** Round ## Images ![50 uF ±5% 50 MFD 370 V/450 V CBB65 Round Run Start Capacitor for AC Motor Run or Fan Start and Cool or Heat Pump Air Conditione - Image 1](https://m.media-amazon.com/images/I/61sdbFrW1YL.jpg) ## Questions & Answers **Q: This capacitor replaces the capacitor that i have defective arcotronics 50uf (c.87.0ef3 mkp) ?** A: I can't find the specs for your arcotronics capacitor. Please look on your capacitor to see if you can find the voltage. If is 370 or 450 volts (370/450V) then this capacitor should work for your application. If the voltage is something else or missing then i'm afraid I can't answer your question. Good luck! **Q: Will this replace a cbb65 (rohs) 55uf =- 5% 450vac c 40/70/21 50/60 hz from a kenmore 253.70251 window unit?** A: I’m not an expert… I got this for a RV AC unit, but all the specs match so, yes. **Q: currently have a 45 uf +/- 6% 440 vac mars brand can i use this one as replacement even though its a 50uf rating ??** A: No I would not do that ,try to stick to the original value. A lower value could make the motor run not optimal. **Q: replacing 50uf +5 370vac 50/60hz 40/85/21 - is this unit compatible?** A: Because the capacitance is 50uf, not 50+5uf, this unit is not compatible.
