Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm plating thickness and material specifications. Ensure compatibility with target PCB edge thickness and polarizing key requirements before procurement. Cross-reference RoHS compliance status with the latest manufacturer datasheet to meet regulatory standards.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 54-position interface is required with a 3.96 mm pitch. Confirm that the vertical panel mount style aligns with the mechanical enclosure design. Validate that the 5 A current rating and thermal performance meet the system's operational demands under maximum load conditions.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is designed for reliable signal and power transmission in demanding environments. The 305-054-556-212 variant specifically addresses applications needing high-density connections with standardized spacing and robust mechanical retention.

Edgeboard Connectors Replacement Considerations

Consult EDAC technical support for verified cross-references. Ensure substitute parts match the 54-position count, 3.96 mm pitch, and dual-row configuration. Verify identical mounting style and contact termination methods to maintain mechanical and electrical integrity.
