Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm pin count, pitch, and termination style. Ensure compatibility with mating connectors within the Archer M50 series. Check for RoHS compliance status and material certifications required for your specific application environment before finalizing procurement.

Headers, Male Pins Selection Notes

Select this component when a high-density 1.27 mm pitch connection is required in a vertical orientation. The through-hole design offers mechanical robustness compared to surface mount alternatives. Consider the 1 A current rating and operating temperature limits to ensure suitability for the target electrical load and environmental conditions.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 series, designed for compact and reliable interconnect solutions. The series utilizes a 1.27 mm pitch to maximize connection density on printed circuit boards. The M50-3503742 variant specifically addresses applications requiring 74 positions with vertical through-hole termination.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.27 mm pitch, 74-position count, vertical orientation, and through-hole termination. Verify that alternative headers maintain identical contact materials, housing flammability ratings, and current specifications to ensure functional interchangeability.
