Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm terminal style, plating thickness, and flange options. Ensure the selected variant matches the required PCB thickness tolerance and mounting hardware specifications. Cross-reference the RoHS compliance status and environmental ratings with the latest product documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector based on the required 40-position count and 3.96 mm pitch compatibility with the target PCB layout. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure design constraints. Evaluate the thermal operating range requirements against the specified -40°C to +105°C limits. Ensure the solder lug termination method is compatible with the assembly process and board pad design.
