Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to confirm specific contact plating, housing color, and termination style. Ensure compatibility with the target PCB thickness and slot width specifications. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component based on the required 56-position count and 3.175 mm pitch. Verify that the vertical orientation fits the mechanical enclosure constraints. Ensure the 3 A current rating meets the application's electrical load requirements. Confirm the PC pin termination matches the available PCB pad layout and manufacturing capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 346 Series, which offers a range of standard card edge connectors. The series provides various position counts and termination options to suit different design needs. These components are widely used in applications requiring reliable, high-density connections between circuit boards and backplanes or chassis-mounted interfaces.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 346 series variants for equivalent position counts and pitch. Verify mechanical dimensions and electrical ratings match exactly. Consult official substitution guides for compatible alternatives with identical termination styles and mounting orientations.
