935C4W5K Film Capacitor Equivalent & Substitute Parts

Part Overview

The 935C4W5K is a 5 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 400V DC voltage rating, designed for high-frequency and switching applications. This component features a polypropylene (PP) metallized dielectric in an axial through-hole package.

The 935C4W5K is classified as obsolete. Locating direct replacements is necessary for ongoing maintenance, repair, and new design implementations where this capacitor specification is required. The substitute part 935C4W5K-F provides functional equivalence with updated product status and improved compliance characteristics.
