C44PLGR6300ZASJ Film Capacitor Equivalent & Substitute Parts

Part Overview

The C44PLGR6300ZASJ is a 300 µF film capacitor manufactured by KEMET, rated for 700V DC and 330V AC operation. This component utilizes polypropylene (PP) metallized dielectric technology in a radial, can-style package with threaded male termination for chassis and stud mount applications. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement capability in power factor correction, commutation, and EMI/RFI suppression circuits.
