Edgeboard Connectors Procurement Notes

Verify the specific suffix code against manufacturer documentation to confirm exact plating thickness and material specifications. Ensure compatibility with target PCB edge card dimensions and hole patterns. Confirm RoHS3 compliance status for regulatory adherence in restricted regions. Cross-reference lead times with authorized distributors as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this connector when a 16-position dual-edge interface with a 3.96mm pitch is required. Ensure the host PCB accommodates the specified 0.054 to 0.070 inch thickness range. Verify that the operating environment falls within the -40°C to 105°C temperature limits. Consider the through-hole mounting style for mechanical stability during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options for diverse electronic applications.
