M50-3904542

Headers, Male Pins Overview

The Harwin M50-3904542 is a right-angle male pin header from the Archer M50 series, featuring a 1.27 mm pitch and 4 positions in a single row. Designed for through-hole mounting, it utilizes phosphor bronze contacts with gold plating to ensure reliable signal transmission. The connector supports a current rating of 1A per contact and operates within a temperature range of -40°C to +105°C. Constructed with a polyamide (PA) housing, it is suitable for board-to-board and wire-to-board applications requiring compact interconnection solutions.

Headers, Male Pins Feature Summary

• Right-angle configuration facilitates dense circuit board layouts
• Gold-plated phosphor bronze contacts provide corrosion resistance
• Polyamide housing ensures thermal stability and UL 94 V-0 flammability rating

Headers, Male Pins Applications

• Board-to-board interconnections
• Wire-to-board connections
• Compact electronic device assembly

Headers, Male Pins Procurement Notes

Verify the specific part number against official Harwin documentation to confirm availability and lead times. Ensure compatibility with mating sockets regarding pitch and row configuration. Check for RoHS compliance status if required by project specifications. Confirm that the right-angle orientation meets mechanical clearance requirements on the target PCB layout.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle connection is necessary for space-constrained designs. The 1.27 mm pitch allows for high-density wiring compared to standard 2.54 mm headers. Consider the 1A current rating for power distribution needs. Verify that the through-hole termination method aligns with the manufacturing process capabilities of the assembly line.

Headers, Male Pins Part Context

This component belongs to the Archer M50 series, which offers a comprehensive range of 1.27 mm pitch connectors. The series includes various configurations such as straight and right-angle headers, IDC sockets, and cable assemblies. The M50-3904542 specifically addresses the need for small-footprint, reliable interconnects in modern electronics where vertical space is limited.

Headers, Male Pins Replacement Considerations

Compatible mating parts include Harwin M50 series female IDC sockets and pin headers with matching 1.27 mm pitch. Ensure replacement components maintain the same single-row configuration and right-angle orientation. Verify that alternative suppliers offer equivalent material properties and electrical ratings.
