Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, termination style, and flange specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status through the latest datasheet revision. Cross-reference the Mouser or DigiKey part numbers for accurate sourcing channels as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection with a 3.96 mm pitch is required for high-current applications up to 5 A. The vertical panel mount style suits enclosures requiring direct board insertion. Verify that the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper contact engagement and mechanical retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for robust construction. The series offers various position counts and termination options. The 305-066 variant specifically addresses needs for moderate-density connections in industrial environments, balancing contact count with manageable form factor dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pitch and mounting style but different position counts, such as 305-050-520-578 or 305-070-556-568. Ensure any replacement matches the 66-position requirement and dual-edge specification to maintain electrical continuity and mechanical fit.
