M50-3901542

Headers, Male Pins Overview

The Harwin M50-3901542 is a male pin header from the Archer M50 series, designed for board-to-board connections. It features a 1.27 mm (0.05 in) pitch with 30 positions arranged in two rows. The connector utilizes through-hole termination and is oriented at a right angle. Contact plating consists of selective gold over nickel, while the base material is phosphor bronze. The housing is constructed from liquid crystal polymer (LCP), rated UL 94 V-0. It supports a current rating of 1 A and operates within a temperature range of -40°C to +105°C.

Headers, Male Pins Feature Summary

• Right-angle through-hole mounting configuration for space-constrained PCB layouts
• Selective gold contact plating ensures reliable signal transmission and corrosion resistance
• High-performance LCP housing provides dimensional stability and high thermal resistance

Headers, Male Pins Applications

• Industrial control systems requiring robust interconnects
• Automotive electronics modules
• Communication equipment backplanes
• Test and measurement instrumentation

Headers, Male Pins Procurement Notes

Verify that the specific part number matches the required 30-position, right-angle configuration. Confirm that the selective gold plating meets the application's conductivity requirements. Ensure the through-hole footprint on the target PCB aligns with the 1.27 mm pitch specifications. Check for any RoHS compliance documentation if required by the manufacturing process.

Headers, Male Pins Selection Notes

Select this component when a right-angle connection is necessary to interface with adjacent components or connectors. The 1.27 mm pitch offers a balance between density and ease of assembly. The Archer M50 series compatibility allows for integration with other headers and jumper sockets within the same ecosystem. Consider the thermal limits of the LCP housing for high-temperature soldering processes.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 family, which specializes in high-reliability interconnect solutions. The series is characterized by its compact 1.27 mm pitch and durable construction suitable for demanding environments. The M50-3901542 specifically addresses the need for angled connections, providing flexibility in mechanical design compared to standard straight headers.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Harwin M50 series headers with equivalent position counts and orientation. Verify that alternative suppliers offer matching 1.27 mm pitch and right-angle geometry. Ensure that contact plating materials and housing flammability ratings meet or exceed the original specifications.
