M50-3903742

Headers, Male Pins Overview

The Harwin M50-3903742 is a 74-position right-angle header within the Archer M50 series. It features a 1.27 mm (0.05 in) pitch and utilizes two rows of male pin contacts. Designed for through-hole mounting, it supports board-to-board or cable-to-board connections. The connector operates within a temperature range of -40°C to +105°C and carries UL 94 V-0 flammability ratings.

Headers, Male Pins Feature Summary

• Right-angle configuration facilitates compact vertical interconnects
• Dual-row layout maximizes contact density on limited board space
• Through-hole termination ensures robust mechanical stability

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Compact electronic module assembly
• Vertical signal routing in constrained enclosures

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required 74-position count and right-angle orientation. Confirm that the through-hole mounting style aligns with the target PCB design. Ensure the operating environment remains within the specified -40°C to +105°C thermal limits for reliable performance.

Headers, Male Pins Selection Notes

Select this component when high I/O density is required in a vertical form factor. The 1.27 mm pitch offers a balance between spacing and capacity. Consider the right-angle profile for space-saving designs where standard headers would exceed height constraints.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 series, which specializes in high-density interconnect solutions. The series is engineered for applications requiring reliable connections in tight spaces, offering various configurations including straight and angled options with different row counts.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 74-position count, 1.27 mm pitch, and right-angle through-hole format. Verify compatibility with mating connectors from the same series to ensure proper alignment and electrical continuity.
