Edgeboard Connectors Procurement Notes

Verify the specific contact finish and housing color against official EDAC documentation before procurement. Confirm that the 1.57 mm board thickness requirement aligns with the target PCB design. Ensure the vertical panel mount style matches the mechanical enclosure constraints. Cross-reference the 26-position count to prevent mismatched assembly errors during integration.

Edgeboard Connectors Selection Notes

Select this component when a single-row card edge interface with high thermal resistance is required. The 3.96 mm pitch accommodates standard board layouts while maintaining robust electrical performance. Consider the 5 A current rating for power distribution needs. Verify compatibility with existing panel mounting hardware and soldering processes to ensure seamless implementation in the final assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of standard card edge connectors, which are engineered for durability in demanding environments. The series provides various position counts and mounting styles to support diverse electronic interconnect requirements. As a high-temperature variant, it distinguishes itself through specialized material selection suitable for elevated operational conditions compared to standard commercial-grade alternatives.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified alternative part numbers. Generic equivalents may not match the specific PPS housing properties or gold plating specifications. Ensure any substitute maintains the identical 3.96 mm pitch and 26-position count to preserve mechanical fit.
