Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm contact plating, flange features, and termination type. Ensure compatibility with the target board thickness and mounting constraints before procurement. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Edgeboard Connectors Selection Notes

Select this connector when a single-row, right-angle card edge solution is required for high-temperature operation. Verify that the 3.96 mm pitch matches the PCB layout requirements. Ensure the panel mount style aligns with the mechanical enclosure design. Confirm that the 5 A current rating meets the electrical load demands of the application circuit.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series of standard card edge connectors. The series offers various position counts and termination options. The 857-025-427-107 specifically provides a 25-position configuration with gold contacts and PPS insulation, distinguishing it from tin-plated or different pitch variants within the same family.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for compatible alternatives. Verify identical pitch, position count, and mounting style when selecting substitutes.
