Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact physical dimensions and plating specifications. Ensure compatibility with target PCB edge thickness and mounting hole patterns before procurement. Confirm RoHS compliance status through manufacturer documentation.

Edgeboard Connectors Selection Notes

Select this component when a high-density 54-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention without excessive board space consumption. Verify that the 5 A current rating aligns with the power distribution requirements of the connected circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which offers various position counts and mounting styles. The series is characterized by its standardized 3.96 mm pitch and durable construction suitable for repeated insertion cycles in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-054-556-278 or 305-054-556-212 if different mounting flanges or packaging options are required. Ensure substitute parts maintain identical pitch and row configuration.
