Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to ensure compatibility with required flange styles and termination types. Confirm that the selected variant matches the intended PCB thickness and mounting constraints. Cross-reference the RoHS status and material declarations with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface with a 3.96 mm pitch is required. Ensure the mating card thickness falls within the specified 1.37 mm to 1.78 mm range. Consider the vertical panel mount style if space constraints or mechanical stability are primary design factors compared to surface mount alternatives.
