Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and material specifications. Ensure compatibility with the target PCB edge thickness of 1.57 mm. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements. Cross-reference the 72-position count with system interface needs.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 72-position capacity suits applications needing extensive I/O connections in a compact footprint. The gold plating offers superior corrosion resistance compared to tin variants. Verify that the vertical mounting constraint fits within the available chassis depth.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and termination options. The 305-072-555-558 specifically addresses the need for a 72-position dual-row solution. It complements other parts in the family by offering different mounting angles and contact finishes.

Edgeboard Connectors Replacement Considerations

Direct substitutes include 305-072-555-504 and 305-072-555-568. These alternatives share the same 72-position count and 3.96 mm pitch but may differ in termination type or housing material. Verify mechanical fit and electrical ratings before substitution.
