Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and plating thickness. Ensure compatibility with the target PCB stack-up and mounting hole patterns before procurement. Cross-reference the component number with authorized distributors to confirm availability status and lead times.

Edgeboard Connectors Selection Notes

Select this component when a robust, high-density connection is required for double-sided cards. The 3.96 mm pitch allows for substantial trace clearance compared to finer pitches. Consider the panel mount style if space constraints on the main chassis allow for external access. Verify that the 5 A current rating meets the power distribution requirements of the application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which focuses on standard card edge connectors for general-purpose industrial and commercial use. The series offers various position counts and row configurations. The 305-040 variant specifically addresses mid-range density needs, balancing connectivity volume with manageable footprint size for standard enclosure designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers or housing colors. Verify mechanical fit and electrical ratings before swapping. No alternative cross-brand equivalents are confirmed in public documentation.
