305-072-520-212

Edgeboard Connectors Overview

The EDAC Inc. 305-072-520-212 is a standard card edge connector receptacle featuring 72 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for PCB mount installation with a straight orientation. The contacts are gold-plated copper alloy, rated for 5 A current, while the thermoplastic polyester housing provides insulation resistance of 5 GOhms. Operating temperatures range from -40°C to +105°C, accommodating board thicknesses of 1.57 mm.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific plating thickness, contact material variations, and packaging quantities. Ensure compatibility with mating card edge thickness specifications before procurement. Cross-reference manufacturer datasheets for updated environmental compliance status and recommended soldering profiles to guarantee assembly integrity.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required with a 3.96 mm pitch. Confirm that the application environment stays within the specified -40°C to +105°C operating range. Verify that the PCB layout supports straight mounting and that the 1.57 mm board thickness aligns with the connector's mechanical constraints for proper engagement.

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 styles, maintaining consistent 3.96 mm pitch characteristics across models. The 305 series is engineered for general-purpose electronic applications requiring durable, high-cycle connection solutions in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-072-520-204 and 305-072-521-202. Verify pinout compatibility and mechanical dimensions before substitution. Alternative manufacturers may offer similar specifications but require validation of contact geometry and insulation resistance ratings.
