Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact mechanical dimensions and termination style. Ensure compatibility with the target PCB layout regarding hole patterns and mounting requirements. Cross-reference the part number with the latest EDAC documentation to confirm availability status and compliance certifications before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row connection is required for thick circuit boards. The 3.96 mm pitch allows for robust signal routing compared to finer pitches. Consider the through-hole mounting method for applications requiring high mechanical strength during insertion cycles. Verify that the operating temperature range meets the environmental demands of the intended deployment scenario.

Edgeboard Connectors Part Context
