305-070-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-070-556-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 70 positions with a 0.156-inch (3.96 mm) pitch and supports a maximum operating temperature of +105°C. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. Rated for 5 A current, it accommodates PCB thicknesses between 1.37 mm and 1.78 mm. This straddle-mount receptacle provides reliable electrical interconnection in demanding environments.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, plating thickness, and mounting variations. Ensure compatibility with target PCB thickness specifications before ordering. Cross-reference RoHS compliance status with current manufacturer declarations. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Edgeboard Connectors Selection Notes

Select this component when dual-edge connectivity is required for high-density signal routing. The 3.96 mm pitch suits applications needing wider spacing than standard micro-connectors. Verify that the 5 A current rating meets system power requirements. Ensure the straddle mount style aligns with chassis design constraints and panel cutout dimensions.

Edgeboard Connectors Part Context

Part of the EDAC 305 series, this connector addresses needs for durable card edge interfaces. The series offers various position counts and mounting options.
