TE Connectivity Erni 225012 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Erni 225012 is a 200-position header connector with 2mm press-fit termination designed for backplane and interconnect applications. This connector features male pins configured for through-hole mounting with a 0.079" (2.00mm) pitch across 8 rows.

The 225012 has reached obsolete product status, necessitating identification of functionally equivalent active alternatives to maintain design continuity and ensure supply chain availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 225012 is determined by strict equivalence across the following critical parameters:

Position Count: 200 positions (exact match required)

Pitch Specification: 0.079" (2.00mm) center-to-center spacing (exact match required)

Connector Type: Header configuration with male pins (exact match required)

Termination Method: Press-fit technology (exact match required)

Mounting Configuration: Through-hole PCB mounting (exact match required)

The substitute part 3-5646729-0 satisfies all these criteria and maintains functional and mechanical compatibility with the obsolete 225012 across all specified parameters.
