Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, flange characteristics, and mounting hardware compatibility. Ensure that the procurement channel provides valid traceability and RoHS compliance certificates. Cross-reference the part number with the latest distributor catalogs to confirm availability status and lead times, as supply chain conditions may vary by region and time.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for vertical panel mounting. Confirm that the target printed circuit board thickness falls within the specified range of 1.37 mm to 1.78 mm. Evaluate the need for gold plating on copper alloy contacts for long-term reliability in corrosive environments. Consider the 5 A current rating and 5 GOhms insulation resistance for electrical safety margins in the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and mounting options to accommodate different board designs.
