Replacing Mallory Capacitor CG152U50B1

Please use this recommendation for reference only, this is our best option based on the available information; always verify any substitutes before using them in your application.

If you are in need of a replacement option for Mallory capacitor # CG152U50B1, but having difficulty, Cornell Dubilier Knowles currently offers CG152U050R3C (DigiKey Part Number: CG152U050R3C-ND).

This appears to be a good replacement based on the specifications and part markings on the original capacitor. The Mallory part number seems to be defunct and Mallory is now Cornell Dubilier (which itself was acquired by Knowles Corporation).

The markings on the Mallory version are shown in the below photo:

Note: The “MFD” is an older way of notating “microfarads” which is now normally marked with a “uFD,” “UFD,” or “µFD.” It looks like this hasn’t been manufactured for some time, as I could only find the specs on third party or distributor sites, nothing from a primary source. This site was the best information I could find for specs that aren’t clearly defined by the markings: TEDSS.COM CG152U50B1
