Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact termination style and plating specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the selected variant meets the required environmental operating temperatures and current ratings for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. The 40-position count suits applications needing moderate I/O density in a compact form factor. Consider the vertical panel mount style for chassis integration and verify that the solder lug termination aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent electrical characteristics and mechanical dimensions. The 305 series is designed for robust performance in demanding environments requiring reliable high-density interconnections.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305-series variants such as 305-040-520-268 or 305-040-555-208 if different termination styles or row spacings are needed. Verify that any substitute maintains the same 3.96 mm pitch and 1.57 mm board thickness compatibility.
