M50-3651742R

Headers, Male Pins Overview

The Harwin M50-3651742R is a surface-mount male header from the ARCHER M50 series, featuring a 1.27 mm pitch and dual-row configuration with 34 positions (17+17). It utilizes brass contacts with gold plating and an LCP housing rated UL 94 V-0. The component supports a current rating of 1.75 A per contact and operates within a temperature range of -55°C to +125°C. Designed for vertical SMT installation, it incorporates a latching mechanism for secure mating.

Headers, Male Pins Feature Summary

• Vertical surface-mount design with integrated latching function for secure board attachment
• Gold-plated brass contacts ensure reliable signal transmission in dual-row configuration
• High-temperature Liquid Crystal Polymer housing provides structural stability and flammability resistance

Headers, Male Pins Applications

• High-density electronic assemblies requiring robust surface-mount interconnects
• Industrial control systems operating in elevated temperature environments
• Consumer electronics utilizing compact dual-row connector architectures

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when sourcing. Confirm that the 1.27 mm pitch matches the target PCB footprint layout. Ensure compatibility with the ARCHER M50 mating system for proper latching engagement. Check RoHS compliance documentation for final assembly requirements.

Headers, Male Pins Selection Notes

Select this part for applications demanding high thermal resilience up to 125°C and secure mechanical retention via latching. The 1.75 A rating suits moderate current loads. Consider the vertical profile for space-constrained designs. Verify that the gold contact finish meets corrosion resistance needs for the operational environment.

Headers, Male Pins Part Context

This component belongs to the ARCHER M50 family, known for high-reliability interconnects. The M50 series offers various configurations including IDC and standard headers. The M50-3651742R specifically addresses the need for latchable SMT solutions in dense PCB layouts, distinguishing itself from non-latching variants through its secure locking feature.

Headers, Male Pins Replacement Considerations

Direct substitutes within the ARCHER M50 series include other 34-position vertical SMT headers. Variants without latching mechanisms may fit mechanically but lack retention security. Non-Harwin equivalents require strict verification of pitch, height, and latching interface compatibility.
