TE Connectivity Erni 124335 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 124335 is a 200 Position Header connector with male pins, featuring 0.079" (2.00mm) pitch and through-hole press-fit termination. This backplane connector is designed for applications requiring high-density interconnection across 8 rows with gold-plated contacts rated for -55°C to 125°C operation.

The 124335 is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production support. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign or board layout modifications.
