TE Connectivity 5-966443-0 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 5-966443-0 is a vertical rectangular connector header from the AMPMODU Mod II series, designed for through-hole board-to-board or cable applications. This 50-position connector operates at 0.100" (2.54mm) pitch with male pin contacts and solder termination. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign.
