Amphenol ICC 74286-645LF Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 74286-645LF is a 90-position receptacle connector designed for board-to-board applications with 0.050" (1.27mm) pitch spacing. This surface mount connector features gold-plated mating contacts and is part of the Rib-Cage™ series. The main part is currently listed as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The substitute part 87024-645LF provides functional continuity with active product status and identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The 87024-645LF qualifies as a direct substitute for the 74286-645LF based on identical alignment across all critical substitution parameters:

Electrical Parameters: Both parts maintain identical contact configuration (90 positions, female socket), pitch spacing (0.050"), contact material (beryllium copper), and contact finish specifications (gold plating at 30.0µin thickness).

Mechanical Parameters: Both connectors share identical mounting type (surface mount), termination method (solder), fastening mechanism (push-pull), insulation material (thermoplastic, glass-filled), and physical dimensions including row spacing and insulation height.

Environmental & Compliance Parameters: Both parts carry identical material flammability rating (UL94 V-0), moisture sensitivity level (MSL 1), and ECCN classification (EAR99).

The primary distinction is product status: 74286-645LF is obsolete while 87024-645LF maintains active status with current inventory availability.
