Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the inclusion of card guides and termination style. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the dual-edge female contact type matches the system requirements. Check RoHS compliance status if environmental regulations apply to the assembly. Validate the mounting orientation against the mechanical constraints of the enclosure.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 42 positions is required. The 0.156-inch pitch suits applications needing wider spacing for high-current or high-voltage isolation. The straddle mount option provides stability without additional hardware. Consider the integrated card guides for simplified assembly processes. Evaluate the thermal rating against the operational environment of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various mounting styles and termination options. The series includes headers and connectors for diverse card edge applications. The 305-042-555-258 specifically addresses dual-edge needs with integrated guidance features. It complements other variants in the lineup that may differ in position count or mounting configuration.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch but different mounting or termination styles. Verify that any replacement maintains the 0.156-inch pitch and 42-position requirement. Ensure the new part supports the same PCB thickness and dual-edge interface. Cross-reference mechanical drawings to confirm fitment in the existing assembly.
