Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, material composition, and environmental ratings. Ensure compatibility with target PCB thickness and mounting requirements before procurement. Cross-reference manufacturer datasheets for any recent design changes or obsolescence notices. Confirm RoHS compliance status through official certification documents rather than distributor summaries.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 20 positions and 3.96 mm pitch is required. Verify that the application environment stays within the specified -40°C to +105°C operating range. Ensure the PCB thickness matches the 1.57 mm specification for proper retention. Consider the vertical panel mount style for integration into chassis-based designs requiring direct card insertion.
