Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating and housing color specifications. Confirm that the 84-position variant matches the required board thickness and mounting style for the target application. Cross-reference the part number with the latest EDAC documentation to validate availability and compliance status before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for vertical panel installation. Ensure the design accommodates the 1.57 mm PCB thickness constraint. Verify that the 5 A current rating and thermal operating range meet the system's electrical and environmental demands. Compare against other 305 series variants if different position counts or mounting styles are needed.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts ranging from low to high density. The series maintains consistent 3.96 mm contact spacing across models, facilitating standardized mechanical designs. The 305-084-556-278 represents a high-pin-count option within this family, suitable for applications demanding extensive I/O connections in a compact vertical form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-080-556-278 (80 positions) and 305-084-556-203, provided pin count and mounting requirements align. Verify mechanical compatibility and electrical ratings before swapping components.
