Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact termination style and plating specifications. Ensure compatibility with target PCB layout dimensions and mounting requirements before procurement. Confirm RoHS compliance status through manufacturer datasheets.

Edgeboard Connectors Selection Notes

Select this connector when high-density dual-row connectivity is required for panel-mounted or surface-mount applications. Evaluate the 0.156-inch pitch against available board space constraints. Consider the 5 A current rating and operating temperature range relative to the system's thermal environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-084 variant provides a high-contact count solution within the family, maintaining consistent dimensional standards across related models.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC part numbers sharing the same 305 series base but differing only in suffix codes for alternative termination styles. Verify mechanical fit and electrical ratings match before substituting.
