M50-3903842

Headers, Male Pins Overview

The Harwin M50-3903842 is a male header connector from the Archer M50 series, featuring a 1.27 mm pitch and 76 positions. It utilizes a right-angle through-hole mounting style with solder termination. The contacts are gold-plated phosphor bronze, housed in black polyamide (PA) insulation rated UL 94 V-0. Designed for board-to-board and wire-to-board applications, it operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• High-density 76-position configuration in a compact right-angle form factor
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Polyamide housing provides UL 94 V-0 flammability rating
• Supports both board-to-board and wire-to-board interconnection systems

Headers, Male Pins Applications

• High-density board-to-board interconnections
• Wire-to-board assembly applications
• Industrial control modules requiring robust connectivity
• Consumer electronics with space constraints

Headers, Male Pins Procurement Notes

Verify the exact position count and housing material against the official Harwin datasheet before procurement. Confirm that the right-angle through-hole specification matches the target PCB layout requirements. Ensure compatibility with mating connectors within the Archer M50 series to guarantee proper mechanical fit and electrical performance.

Headers, Male Pins Selection Notes

Select this component when high pin density is required in a limited footprint. The right-angle design facilitates vertical stacking or specific board orientations. Verify that the 1.27 mm pitch aligns with existing PCB silkscreen and drill patterns. Consider the operating temperature range and flammability rating for environmental compliance.

Headers, Male Pins Part Context

This part belongs to the Harwin Archer M50 series, known for its fine-pitch 1.27 mm spacing. The series offers various configurations including straight and right-angle headers, as well as different row counts. The M50-3903842 specifically addresses needs for high-count interconnects in a single-row right-angle format.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 1.27 mm pitch, 76-position count, and right-angle through-hole mounting. Verify contact plating and housing material specifications to ensure equivalent electrical and mechanical performance. Cross-reference with other manufacturers offering similar fine-pitch header solutions.
