Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and flange specifications. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status through current manufacturer datasheets as regulatory requirements may evolve.

Edgeboard Connectors Selection Notes

Select this component when a high-density 54-position connection is required in a vertical orientation. The 3.96 mm pitch allows for substantial trace spacing. Verify that the application environment stays within the specified thermal limits and that the mating card fits the designated thickness tolerance.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles, widely used in general-purpose electronics where reliable signal transmission between a circuit board and a chassis or backplane is essential.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-054-520-502 or 305-054-556-278 if different housing materials or terminal configurations are acceptable. Ensure mechanical footprint and electrical ratings match exactly before substitution.
