Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct pin count, plating thickness, and mounting style. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the datasheet dimensions to validate panel cutout requirements before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 70 positions and 3.96 mm spacing is required. Ensure the target PCB thickness matches the 1.57 mm specification. Consider the 5 A current rating and 1800 VACrms insulation voltage for electrical safety margins. Verify compatibility with polarizing keying systems if mechanical alignment is critical for the assembly process.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in high-reliability applications. The series offers various position counts and mounting styles, providing flexibility for different board densities. The 305-070-556-504 specifically addresses needs for dual-edge interfaces with standardized spacing, fitting into broader system architectures requiring stable electrical connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts like 305-070-556-502 or 305-070-556-568, provided they match the 70-position count and 3.96 mm pitch. Verify that alternative part numbers maintain identical row spacing, current ratings, and mounting configurations to ensure mechanical and electrical compatibility without redesigning the host assembly.
