Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating, insulator color, and mounting style compatibility. Ensure the polarizing key requirements match the system design before procurement. Cross-reference the part number with authorized distributors to confirm authenticity and avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection with a 3.96mm pitch is required. Consider the 5A current rating and 1800VACrms insulation strength for high-power or high-voltage applications. Verify that the P.C. tail termination fits the PCB manufacturing capabilities and that polarizing key slots are accommodated in the design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides various mounting options and configurations for card edge applications. The series is known for supporting complex interconnect solutions in computing, medical, and industrial sectors. The 305-074-520-204 specifically addresses the need for 74-position connections with robust electrical ratings.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with different row counts or mounting styles, such as the 305-018-520-204 or 305-058-520-204, provided the pitch and contact type remain compatible. Verify mechanical fit and electrical specifications before substitution.
