305-038-521-202

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-202 is a standard card edge connector from the 305 series, designed for vertical panel mount applications. It features 38 positions with a 3.96 mm (0.156 inch) contact spacing and supports dual-edge card types. The connector utilizes copper alloy contacts with gold plating and a thermoplastic polyester insulator. Rated for 5 A current, it accommodates board thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact pin count, plating thickness, and material specifications. Ensure compatibility with target PCB thickness ranges before integration. Cross-reference datasheet revisions to confirm compliance with current environmental directives such as RoHS and REACH standards.

Edgeboard Connectors Selection Notes

Select this component when a 38-position vertical 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 mating card edge thickness falls within the 1.37 mm to 1.78 mm tolerance window for proper mechanical 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, utilizing consistent 3.96 mm spacing across models. The 305-038 variant specifically addresses mid-density connection needs in compact panel-mounted assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 38-position, 3.96 mm pitch vertical card edge connectors from EDAC or compatible manufacturers. Verify identical flange dimensions, contact length, and insulation material properties before substitution.
