Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact mechanical dimensions and termination styles. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity. Check for RoHS compliance requirements if applicable to the end product.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 84 positions is required. The 3.96 mm pitch suits applications needing wider spacing between rows. Verify that the panel or board layout accommodates the vertical mounting style. Consider the gold plating requirement for environments where oxidation resistance is critical for long-term reliability.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various mounting options and position counts. The series is characterized by low-profile insulator bodies and standardized spacing. It serves as a reliable interface solution for connecting edgeboards to main system boards in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-084-500-202 and 305-084-500-278. Verify that alternative suffixes match the required termination style and mounting orientation. Ensure the replacement maintains the same 84-position count and 3.96 mm pitch specifications.
