Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm contact plating, housing color, and termination type. Ensure the selected variant matches the required PCB thickness and mounting style. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number with distributor catalogs to avoid confusion with similar series components.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with 72 positions is required. The 3.96 mm pitch accommodates standard board layouts. Verify that the application environment stays within the -40°C to +105°C operating range. Ensure the mating card edge thickness falls within the specified 1.37 mm to 1.78 mm tolerance. Consider the 5 A current rating for power distribution needs.

Edgeboard Connectors Part Context
