Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific plating thickness and material variations. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure compatibility with the target PCB stack-up and card thickness specifications defined in the datasheet.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required. The 3.96 mm pitch accommodates standard board layouts. Verify that the application environment falls within the specified operating temperature range. Consider the straight mounting style for direct panel or board alignment needs.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 Series of edgeboard connectors. The series offers various position counts and mounting options. The 305-072 variant specifically addresses high-pin-count requirements. It shares design characteristics with other models in the family while differing in terminal count.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 3.96 mm pitch and 72-position count. Verify mechanical dimensions and contact geometry before substitution. Ensure electrical ratings match the original design requirements.
