Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC channels or certified distributors. Confirm RoHS compliance status and specific lot traceability requirements prior to acquisition. Ensure storage conditions maintain integrity of the gold plating and thermoplastic housing against environmental degradation.

Edgeboard Connectors Selection Notes

Select this model when a 22-position vertical header with 3.96 mm spacing is required. Verify compatibility with 1.57 mm thick PCBs and confirm that the 5 A current rating meets circuit demands. Ensure the design allows space for polarizing key integration if mechanical locking is necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts while maintaining consistent 3.96 mm pitch and panel-mount characteristics. It serves as a reliable interconnect solution for modular electronic hardware requiring robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Cross-reference other 305-series variants such as 305-022-521-258 for different plating options. Verify dimensional compatibility with existing panel cutouts and PCB stack-up requirements before substituting.
