305-052-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-052-556-202 is a dual-edge female card edge connector designed for board-to-board applications. It features 50 positions with a 0.156-inch (3.96mm) pitch and two rows of contacts. The connector utilizes gold-plated copper alloy semi-waffle contacts to ensure reliable signal transmission. It supports PCB thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The housing is constructed from green thermoplastic polyester, providing durability and insulation. Operating temperatures range from -40°C to 105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm compatibility with required PCB thickness and termination styles. Ensure that the selected variant matches the intended application environment regarding temperature ratings and RoHS compliance standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 50-position dual-row interface is required for standard card edge applications. Consider the 0.156-inch pitch constraint and verify that the target PCB thickness falls within the specified 1.37mm to 1.78mm range. Evaluate the need for gold plating thickness if high-cycle mating durability is critical for the specific deployment scenario.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options tailored for robust electronic interconnects. The 305-052 model specifically addresses the need for higher density connections in a dual-edge format, maintaining consistency with the series' mechanical and electrical performance standards.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for direct cross-references. Verify pin count, pitch, and mounting style compatibility before substituting with alternative part numbers to ensure mechanical fit and electrical integrity.
