Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact plating thickness and housing color variations. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates prior to final purchase decisions.

Edgeboard Connectors Selection Notes

Select this component when a 54-position dual-edge connector is required with 3.96 mm spacing. Consider the 5 A current rating and 1800 VACrms dielectric strength for electrical requirements. Verify that the application environment falls within the -40 C to +105 C operating temperature range specified for this series.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting styles, providing a modular solution for board-to-board or backplane connections. The 305-054-555-202 specifically addresses applications requiring a high-density 54-position interface with dual-edge engagement capabilities.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing but different mounting styles or termination types. Cross-reference the mechanical dimensions and electrical ratings against alternative manufacturers' offerings to ensure functional equivalence without compromising board layout constraints.
