Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm contact tail geometry and plating specifications. Ensure compatibility with target PCB thickness and panel mounting requirements before procurement. Cross-reference RoHS compliance status with current regulatory standards. Confirm availability through authorized distributors as supply chain conditions may vary.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 48 positions is required. Verify that the 3.96 mm pitch matches the mating card layout. Ensure the operating environment falls within the specified temperature range. Confirm that the 5 A current rating meets circuit demands. Check mechanical fit for panel installation constraints.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and contact configurations. The series is characterized by robust thermoplastic construction and standardized spacing. This specific model represents a dual-row variant optimized for applications requiring multiple signal lines in a compact vertical profile.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers with identical pin counts and spacing but different contact codes or housing colors. Verify mechanical dimensions and electrical ratings before substitution. Consult EDAC official documentation for cross-reference lists.
