Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure that the required polarizing key accessories are sourced separately if mechanical locking is necessary for the assembly. Confirm compliance with RoHS3 standards prior to final procurement approval.

Edgeboard Connectors Selection Notes

Select this model when a robust 20-position interface is required for boards up to 1.57 mm thick. The 5 A current rating and 1800 VACrms insulation capability make it suitable for demanding environments. Verify that the vertical mounting style aligns with the chassis design constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is engineered for durability in harsh conditions, offering consistent performance across various industrial sectors. The 305-020-500-203 variant specifically addresses the need for dual-row connectivity with standardized spacing.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching pin counts and pitch. Cross-reference dimensions carefully to ensure compatibility with existing panel cutouts and board layouts.
