Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC datasheet to confirm exact contact plating thickness and material specifications. Ensure the selected variant matches the required PCB thickness tolerance of 1.37 mm to 1.78 mm. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-edge boards. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Verify that the 5 A current rating meets the circuit requirements. Consider the thermoplastic housing material for environmental resistance within the specified temperature range.

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 styles. The 305 series is characterized by its durability and standardized dimensions, making it suitable for high-reliability industrial and commercial electronic applications requiring stable card-to-board connections.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-026-555-201 for similar form factors. Check EDAC 345-026-555-278 if a different pitch is acceptable. Verify mechanical fit and electrical ratings before substituting.
