Edgeboard Connectors Procurement Notes

Verify the specific datasheet version for the 857-078-520-207 to confirm current RoHS compliance status and detailed dimensional tolerances. Ensure that the receiving facility has the capability to handle panel-mount connectors properly during installation. Cross-reference the official EDAC documentation for any recent updates regarding material specifications or environmental certifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for double-sided printed circuit boards. The high-temperature rating makes it suitable for environments exceeding standard operating limits. Verify that the PCB edge thickness matches the connector's acceptance criteria to ensure proper mechanical retention and electrical contact integrity during assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series of high-temperature card edge connectors. The series is characterized by robust construction and extended thermal stability compared to standard variants. It serves as a critical interconnect solution in sectors requiring durable connections under thermal stress, complementing other EDAC header and D-sub product lines.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC cross-reference guide for verified substitute part numbers. Generic equivalents may not match the specific high-temperature ratings or dimensional tolerances required for panel-mounted installations. Always validate pinout compatibility and mechanical fit before substituting.
