Amphenol ICC 76341-350 Rectangular Connector - Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 76341-350 is a 50-position receptacle connector with 0.100" (2.54mm) pitch, designed for board-to-board applications. This connector features gold-plated mating contacts, tin-plated posts, and through-hole solder termination. The part is classified as obsolete, making identification of suitable alternatives necessary for ongoing design support and procurement planning. The 76341-350LF represents the active production equivalent with enhanced compliance characteristics.

Substitute Part Grouping Explanation

The 76341-350LF qualifies as a direct substitute based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Connector type matches: Receptacle
Position count is identical: 50 positions
Mating pitch is identical: 0.100" (2.54mm)
Board-to-board style configuration
Through-hole mounting with solder termination
Push-pull fastening mechanism
Gold contact finish on mating surfaces
Dubox™ series designation

The primary distinction between the main part and substitute is product status and compliance certification. The 76341-350 is obsolete, while the 76341-350LF is active production with RoHS compliance and REACH affected status.
