M50-3901442

Headers, Male Pins Overview

The Harwin M50-3901442 is a male, right-angle board-to-board connector from the Archer M50 series. It features a 1.27 mm (0.05 in) pitch with 4 contacts arranged in a dual in-line configuration. The component utilizes phosphor bronze terminals with gold plating for reliable signal transmission. Designed for through-hole mounting, it supports solder termination and operates within a temperature range of -40°C to +105°C. The housing is constructed from black polybutylene terephthalate (PBT), ensuring mechanical stability and compliance with UL94 V-0 flammability standards.

Headers, Male Pins Procurement Notes

Verify the specific contact count and orientation against project requirements before ordering. Confirm that the through-hole mounting style aligns with the PCB fabrication capabilities. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the datasheet for precise mechanical dimensions to avoid clearance issues during assembly.

Headers, Male Pins Selection Notes

Select this model when a low-profile, right-angle connection is required for small-scale board stacking. The 1.27 mm pitch offers a balance between density and manufacturability. Consider the gold plating for applications requiring high reliability over multiple mating cycles. Evaluate the PBT material properties for thermal resistance needs.

Headers, Male Pins Part Context

This component belongs to the Harwin Archer M50 series, which specializes in high-density, surface-mount and through-hole connectors. The series is characterized by its robust construction and suitability for space-constrained designs. The M50-3901442 specifically addresses the need for short, right-angle interconnections in multi-layer PCB architectures.

Headers, Male Pins Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.27 mm pitch, 4-contact count, right-angle orientation, and through-hole mounting style. Verify compatibility with existing PCB footprints and mating connectors before substitution.
