Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and flange characteristics. Confirm that the ordering suffix does not alter the fundamental electrical function or mechanical dimensions. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and traceability before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 72-position connection is required for thick PCBs. Ensure the design accommodates the specified 1.57 mm board thickness. Verify that the 5 A current rating and 1800 VACrms insulation requirements align with the system's electrical specifications. Confirm compatibility with available polarizing key options if mechanical locking is necessary.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, designed for reliable card edge connections. The series supports various position counts and row configurations. It is engineered for robust performance in demanding environments, offering consistent electrical contact and mechanical stability for edgeboard applications across multiple industrial sectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-072-521-201 and 305-072-520-204. Verify that alternative suffixes match the required plating and mounting style. Ensure any replacement maintains the 72-position count and 3.96 mm pitch to guarantee physical compatibility with existing PCB layouts.
