## 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. Thanks!
