Edgeboard Connectors Procurement Notes

Verify the specific suffix against official EDAC documentation to confirm exact plating specifications and mechanical tolerances. Ensure the target PCB thickness aligns with the 1.57 mm nominal requirement for proper insertion force and retention. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided card edge applications. The 3.96 mm pitch accommodates high-density routing while maintaining mechanical stability. Consider the 5 A current rating and operating temperature range to ensure compatibility with the system's thermal and electrical loads during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles to support diverse interface requirements. The 305-040 variant specifically addresses applications needing 40 connections with a standardized footprint and reliable performance characteristics.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305-series parts such as 305-040-520-507 or 305-040-556-502 if different mounting styles or plating options are needed. Verify that any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness compatibility to ensure mechanical fit.
