Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to ensure correct termination style and flange options. Confirm RoHS compliance status and mating card specifications before integration. Cross-reference the part number with official EDAC documentation to validate availability and lead times through authorized channels.

Edgeboard Connectors Selection Notes

Select this component when a 42-position dual-row interface is required for vertical panel mounting. Ensure the mating card thickness falls within the 1.37 mm to 1.78 mm range. Verify that the 3.96 mm pitch aligns with the PCB layout requirements and that the 5 A current rating meets the circuit load demands.

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 configurations. The 305-042 variant specifically provides a mid-range density solution for applications requiring robust mechanical retention and electrical continuity in panel-mount scenarios.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-042-556-278 and 305-042-500-504. Verify compatibility regarding termination type and insulation material before substitution. Ensure mechanical dimensions and electrical ratings remain consistent with the original design requirements.
