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.
