Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin count, plating thickness, and mounting style. Ensure compatibility with the target PCB edge thickness range of 0.054 to 0.070 inches. Confirm that the dual-edge design aligns with the assembly requirements. Cross-reference the part number with official EDAC documentation to avoid substitution errors due to minor specification changes.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface is required for space-constrained or high-reliability designs. Consider the 0.156-inch pitch for standard signal routing density. Evaluate the high-temperature capability if the application exceeds standard commercial limits. Verify that the board thickness falls within the specified acceptance range to ensure proper contact engagement and mechanical retention during operation.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series, which specializes in high-temperature card edge connectors. The series is characterized by durable materials and precise dimensional tolerances. It serves as a critical interconnect solution for applications where standard connectors may fail due to thermal stress or mechanical vibration. The dual-edge design offers enhanced stability compared to single-edge variants.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 34-position count, 0.156-inch pitch, dual-edge configuration, and high-temperature rating. Any alternative must be verified against the original mechanical and electrical specifications to ensure functional equivalence.
