305-044-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-044-521-203 is a standard card edge connector from the 305 series, designed for dual female mating configurations. It features 44 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold plated, it supports a current rating of 5 A. The housing utilizes a low-profile thermoplastic insulator body, and the unit is intended for panel mounting applications.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, plating thickness, and flange specifications. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) before procurement. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 44-position interface is required with a 3.96 mm pitch. The 5 A current rating and gold plating suit environments demanding stable electrical performance. Verify that the panel mounting requirement aligns with the mechanical design constraints. Consider the low-profile body height if vertical clearance within the enclosure is limited during the initial design phase.
