Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange specifications. Ensure compatibility with target PCB thickness limits before ordering. Confirm RoHS compliance status through manufacturer datasheets rather than distributor summaries. Validate lead times directly with authorized suppliers as availability fluctuates.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female interface with 3.96 mm pitch is required. Verify that the mating card edge fits within the specified 1.37 mm to 1.78 mm thickness range. Consider the panel mount style and M3 threaded insert requirements for mechanical integration. Ensure the 5 A current rating meets circuit demands.

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. The 305-050 variant specifically addresses high-density connection needs in compact form factors.
