Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct termination style, flange configuration, and plating thickness. Confirm that the required board thickness aligns with the connector's acceptance specifications before finalizing procurement orders to prevent mechanical fitment issues.

Edgeboard Connectors Selection Notes

Select this model when a low-profile, panel-mount solution is required for double-sided card edge applications. Ensure the design accommodates the straddle mount footprint and verify that the 3.96 mm pitch matches the mating card edge layout. Consider thermal requirements as the unit supports up to +105°C operating temperatures.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing versatile interconnect options for modular electronic systems requiring robust mechanical retention and electrical stability in constrained spaces.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 family, such as the 305-038-520-502, ensuring identical pin count, pitch, and mounting orientation. Verify that any substitute matches the original flange features and termination type to maintain assembly compatibility.
