Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct pin count and termination style. Confirm that the required board thickness falls within the specified 0.054 to 0.070-inch range. Check current availability status as distribution may vary by region and time.

Edgeboard Connectors Selection Notes

Select this model when a high-density 66-position connection is required on a double-sided edge card. Ensure the mating PCB has a compatible thickness profile. Consider the 0.156-inch pitch spacing relative to other available series options if space constraints exist. Verify environmental ratings match the operational temperature requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-066 variant specifically addresses applications needing extensive signal or power routing across a dual-edge interface with standardized mechanical dimensions.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with identical electrical characteristics but different packaging or minor mechanical variations. Cross-reference part numbers within the same series for alternative pin configurations.
