Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness and material specifications. Ensure the selected variant matches the required board thickness tolerance of 1.37 mm to 1.78 mm for proper engagement. Confirm RoHS compliance status directly with the supplier documentation prior to procurement.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 43-position interface is required for vertical panel mounting. The 2.54 mm pitch accommodates standard PCB edge layouts. Verify that the application environment remains within the -40°C to +105°C operational range and does not exceed the 3 A current rating per contact.

Edgeboard Connectors Part Context

This part belongs to the EDAC 391 series of standard card edge connectors. The series offers various position counts and termination styles, all sharing consistent mechanical dimensions and electrical ratings.
