Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, contact termination style, and mounting hardware configuration. Ensure compatibility with target PCB thickness and polarizing key requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when requiring a dual-row card edge interface with high voltage isolation capabilities. The 66-position count suits complex signal routing needs. Confirm that the straddle mount style aligns with the chassis design constraints and that the 5A current rating meets the application's power distribution demands.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and termination styles. The series is characterized by robust construction suitable for demanding environments. The 305-066 variant specifically addresses applications needing higher pin counts while maintaining the standard 3.96 mm pitch found across the family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other 305 Series variants such as 305-066-521-202 or 305-066-555-202 if different termination or mounting styles are required. Verify that substitute parts maintain the same 0.156 inch pitch and dual female contact configuration to ensure mechanical and electrical compatibility.
