Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm exact pin count, row configuration, and plating specifications. Ensure compatibility with mating socket assemblies regarding pitch and height. Confirm that the gold plating variant meets the required environmental durability standards for the intended application environment.

Headers, Male Pins Selection Notes

Select this component when a low-profile, dual-row header is required for high-density routing. The horizontal design facilitates compact assembly compared to vertical alternatives. Verify that the 2.54 mm pitch aligns with existing PCB footprint libraries and that the 3 A current rating satisfies the thermal requirements of the connected circuits.

Headers, Male Pins Part Context

This part belongs to the M20 series, which offers a comprehensive range of headers and wire housings. The series is characterized by its robust construction and versatile mounting options, including both surface mount and through-hole variants. The M20-9743042 specifically addresses needs for horizontal, dual-row connectivity with high reliability.

Headers, Male Pins Replacement Considerations

Direct substitutes may include other Harwin M20 series headers with identical 2.54 mm pitch and 40-position dual-row configurations. Verify mechanical dimensions and terminal type compatibility before substitution. Alternative manufacturers offering standard 2.54 mm pitch headers should be evaluated for matching electrical ratings and material composition.
