Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official documentation to confirm exact plating thickness, housing color, and keying options. Ensure that the ordering suffix matches the required polarizing key configuration and contact termination style. Cross-reference the part number with the latest EDAC datasheet to confirm compliance with current RoHS directives and material specifications before final procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required for panel or PCB mounting applications. Confirm that the target printed circuit board thickness aligns with the 1.57 mm specification. Evaluate the 5 A current rating and 1800VACrms insulation requirements against the system's electrical loads. Ensure compatibility with the 305 series housing dimensions and polarizing key slots.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are engineered for high-reliability interconnect solutions. The series provides various position counts and termination styles while maintaining consistent dimensional tolerances. These connectors are widely utilized in environments demanding stable electrical performance and mechanical durability over extended operational lifespans.

Edgeboard Connectors Replacement Considerations

Consult the EDAC official cross-reference guide for verified substitute part numbers.
