Equivalent & Substitute Parts for Sensata-Crydom CWD4890PH Solid State Relay

Part Overview

The Sensata-Crydom CWD4890PH is a solid-state relay (SSR) designed for high-powered AC switching applications. It is a single-pole, normally open (SPST-NO) device capable of handling 90A load currents and is suitable for chassis-mount configurations. Its hockey puck package and screw terminal connections make it compatible with various industrial setups. Finding alternative models is necessary for supply chain flexibility, design redundancy, and qualification processes, especially when maintaining form, fit, and function with existing mechanical and electrical designs.
