Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to confirm contact finish thickness and housing color variations. Ensure compatibility with the target PCB thickness specifications before procurement. Confirm RoHS compliance status through the manufacturer's latest documentation. Cross-reference the part number with authorized distributors to validate availability and lead times. Request datasheets directly from EDAC Inc. for precise mechanical drawings and mating force requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for panel-mounted applications. The straddle mount style offers superior mechanical retention compared to surface-mount alternatives. Verify that the target circuit board thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the 5 A current rating and gold plating for environments demanding high reliability and low contact resistance. Ensure the vertical orientation aligns with the system's spatial constraints.
