Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and insulation material properties. Ensure the target application requires a 3.96 mm pitch and 1.57 mm board thickness compatibility. Confirm that the dual-row wire hole termination aligns with the assembly process requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust panel-mount solution is required for double-sided card edge applications. The 5 A current rating suits moderate power distribution needs alongside signal lines. Consider the physical dimensions and panel cutout specifications to ensure mechanical fit within the enclosure design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse interface requirements. The 305-074 variant specifically addresses applications needing 74 connection points in a dual-row arrangement.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with matching 74-position dual-row layouts. Verify identical pitch and board thickness tolerances when cross-referencing alternative manufacturers' equivalents.
