Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, contact finish, and housing color specifications. Ensure compatibility with the target PCB edge thickness and mounting style requirements before finalizing procurement orders to prevent integration errors.

Edgeboard Connectors Selection Notes

Select this component when a high-density 122-position connection is required in a vertical orientation. The 2.54 mm pitch ensures compatibility with standard edge cards, while the gold-over-nickel finish offers superior corrosion resistance compared to tin variants for long-term reliability in demanding environments.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors, designed for general-purpose industrial and commercial applications. The series offers various position counts and mounting styles, with this specific model providing a dual-row solution for compact high-pin-count interfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 345 series parts for alternative position counts or mounting angles. Verify that any substitute maintains the same 2.54 mm pitch, dual-row configuration, and compatible board thickness to ensure mechanical fit.
