Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's current ordering guide to ensure compatibility with required mounting lugs or tail configurations. Confirm that the gold flash plating specification meets the application's wear requirements. Check for RoHS3 compliance status if environmental regulations apply. Ensure the selected variant matches the exact pin count and row arrangement needed for the target PCB layout.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connector with 1.27mm pitch is required for straddle mounting. Compare against other 302 series variants to determine if additional mounting lugs or different tail lengths are necessary for the specific chassis design. Verify that the board thickness falls within the specified range of 1.30mm to 1.80mm for proper engagement.
