Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the exact contact plating, insulator color, and mounting style. Ensure the target application requires the specified 3.96 mm pitch and 1.57 mm board thickness compatibility. Confirm that the 5 A current rating meets the circuit requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-density 86-position connection is required on a standard 0.062 inch thick PCB. The dual-edge design allows for increased pin count within a compact footprint compared to single-edge alternatives. Verify that the system design can accommodate the necessary polarizing key slots if signal isolation is required.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its robust construction and compatibility with common PCB thicknesses. The 305 series offers various position counts and mounting options to support diverse electronic assembly needs across multiple industries.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts having identical 86 positions and 3.96 mm pitch. Verify mechanical dimensions and electrical ratings against alternative suppliers' offerings to ensure functional equivalence in the final assembly.
