M50-3504142

Headers, Male Pins Overview

The Harwin M50-3504142 is a 82-position vertical header from the Archer M50 series. It features a 1.27 mm pitch and two rows of male pins. Designed for through-hole mounting, it utilizes gold-plated phosphor bronze contacts housed in black thermoplastic insulation. The connector supports board-to-board and wire-to-board applications with a current rating of 1 A and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Vertical pin header configuration for space-constrained PCB layouts
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Thermoplastic housing provides UL 94 V-0 flame retardancy

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• Industrial control systems
• Data center infrastructure

Headers, Male Pins Procurement Notes

Verify the specific contact count and row configuration against official datasheets before ordering. Confirm that the through-hole termination style matches the target PCB fabrication capabilities. Ensure the operating temperature requirements align with the component's specified thermal limits.

Headers, Male Pins Selection Notes

Select this component when high-density interconnects are required on standard thickness PCBs. The 1.27 mm pitch allows for significant I/O density compared to larger spacing options. Consider the vertical orientation for direct mating with corresponding sockets or cables without requiring additional height adapters.

Headers, Male Pins Part Context

This part belongs to the Archer M50 series, which offers various configurations including SMT and IDC variants. The series is designed for high-reliability applications in demanding environments. Other parts in this family share similar electrical characteristics but differ in mounting style and contact arrangement.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M50 series headers with matching 1.27 mm pitch and 82 positions. Verify mechanical compatibility with mating connectors. Cross-reference with equivalent products from other manufacturers only if pinout and dimensions are identical.
