Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. Ensure the target PCB thickness falls within the 1.37 mm to 1.78 mm operational range. Verify that the application environment remains within the -40°C to +105°C temperature limits. Confirm compatibility with polarizing key requirements if mechanical locking is necessary for the assembly design.
