Hi there, My air exchanger motor stopped working and it seems the capacitor is dead. I need to replace it but I don’t know how to find the correct model.

Please see the picture attached of the current capacitor. If you can please post the link of the replacement that would work that would be greatly appreciate it.

Thanks

Hello MMcFly,

Welcome to the DigiKey TechForum.
The closest option I found, is part number 495-B33331I6505J080-ND, which is 5uf, +/- 5%.
This one is 1.181" diameter X 2.244" long, and can handle up to 450VAC max. So will work fine on lower voltages.
The next option is an oblong shaped, which is part number SFA37T5K156B-F-ND.
If you have room for this one, it is a better electrical match. 5uf, 10%, 370VAC. Size is 2.160" X 1.310", and is 1.680" long.
Please check the datasheets to help verify compatibility to your application.
