Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm availability status, as distribution channels may vary by region. Ensure that the selected variant matches the required polarizing key compatibility and voltage ratings for the intended application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row configuration with 3.96 mm pitch is required for 1.57 mm thick boards. Consider the 5 A current rating and 1800 VACrms insulation capability for high-reliability industrial or embedded applications requiring robust panel mounting solutions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, maintaining consistent 3.96 mm contact spacing across models to ensure compatibility within standardized electronic assembly frameworks.

Edgeboard Connectors Replacement Considerations

Cross-reference other 305-series variants such as 305-040-520-268 or 305-038-520-502 if different position counts are needed while maintaining identical pitch and mounting specifications.
