M50-3903542

Headers, Male Pins Overview

The Harwin M50-3903542 is a male pin header from the Archer M50 series, featuring a 1.27 mm pitch and 10 positions in a dual-row configuration. Designed for board-to-board and wire-to-board applications, it utilizes a right-angle mounting style with through-hole termination. The connector employs phosphor bronze contacts with gold plating and a nylon insulator. It supports a rated current of 1A per contact and operates within a temperature range of -40°C to 105°C.

Headers, Male Pins Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Harwin documentation. Confirm that the specific suffix matches the required dual-row, right-angle configuration. Ensure compliance with RoHS standards if applicable to your assembly requirements. Check for any obsolescence notices or lifecycle status updates directly from the manufacturer before finalizing procurement decisions.

Headers, Male Pins Selection Notes

Select this component when a low-profile, right-angle connection is required for dense circuit layouts. The 1.27 mm pitch allows for significant I/O density within limited board areas. Consider the 1A current rating for signal and low-power data lines. Verify that the through-hole mounting method aligns with your PCB fabrication capabilities and mechanical stress requirements.

Headers, Male Pins Part Context

This component belongs to the Archer M50 series, a family of connectors known for their slim profile and robust performance. The series offers various row counts and orientations to suit diverse electronic packaging needs. The M50-3903542 specifically addresses the need for reliable, space-saving interconnections in modern electronic devices requiring high pin counts in a small footprint.

Headers, Male Pins Replacement Considerations

Public records indicate that the M50-3903542 is obsolete and no longer manufactured. Engineers should identify equivalent components from the same manufacturer's current lineup or compatible third-party alternatives that match the 1.27 mm pitch, dual-row, right-angle specifications.
