Edgeboard Connectors Procurement Notes

Verify the specific flange configuration against the official datasheet, as the 387 series includes variants with different mounting hole patterns and thread specifications. Confirm that the required PCB thickness falls within the specified operational range to ensure proper mechanical engagement and electrical continuity during assembly.

Edgeboard Connectors Selection Notes

Select this component when a single-row interface with a 0.156-inch pitch is required. Ensure the application environment remains within the -40°C to +105°C operating temperature limits. Verify compatibility with the target PCB stack-up and mounting constraints before finalizing the design integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 387 Series, which provides a broad range of card edge connectors characterized by a 0.156-inch spacing. The series offers various row counts, termination styles, and flange options to support diverse board-to-board and board-to-backplane connectivity requirements across multiple industries.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 387 Series Ordering Guide for cross-referencing compatible alternatives. Direct substitutes must match the 21-position count, single-row layout, and 0.156-inch pitch specifications to maintain mechanical and electrical integrity in existing designs.
