Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and housing color variations. Ensure that the ordering information matches the required polarizing key configuration and contact termination style before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Confirm that the target printed circuit board accommodates the specified 1.57 mm thickness and that the application environment remains within the -40°C to +105°C operational temperature limits defined by the manufacturer.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its consistent 3.96 mm spacing and robust mechanical design suitable for panel or PCB mounting applications. The 305 series provides a standardized solution for connecting double-sided edge cards in various electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing the same 76-position count and 3.96 mm pitch. Verify mechanical dimensions and electrical ratings to ensure functional equivalence before substituting.
