G125-MS11605M1R

Overview

The G125-MS11605M1R is a Gecko-SL series power-to-board header manufactured by Harwin Inc. It features a 1.25 mm pitch and a 2x8 (16 position) configuration with male pin contacts. Designed for surface mount installation, the connector utilizes gold-plated phosphor bronze terminals housed in green polyamide insulation. The component supports a rated current of 2 A and operates within a temperature range of -65°C to +150°C. Key specifications include a UL94 V-0 flammability rating and a mating stacking height of 7.33 mm or 7.4 mm.

Feature Summary

• Surface mount design with polarized keying and mating flanges
• High-reliability construction supporting 1000 mating cycles
• Gold-plated phosphor bronze contacts for signal integrity

Applications

• Board-to-board interconnects requiring high reliability
• Signal transmission in compact electronic assemblies
• Power distribution in space-constrained environments

Procurement Notes

Verify that the specific suffix M1R corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 1.25 mm pitch and 16-position layout match the target PCB footprint exactly. Ensure compatibility with the specified 7.33 mm or 7.4 mm stacking heights for the intended mechanical enclosure constraints.

Selection Notes

Select this component when a surface mount solution is preferred over through-hole mounting for the Gecko-SL family. The 1.25 mm pitch allows for higher density compared to standard 2.54 mm headers. Consider the 2 A current rating per contact for circuit load requirements and verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the Harwin Gecko-SL series, which focuses on high-reliability interconnects for demanding applications. The series offers various configurations including right-angle and vertical orientations. The G125-MS11605M1R specifically addresses the need for robust surface mount connections with precise alignment features.

Replacement Considerations

Direct substitutes within the same series include G125-MV11605M1P for through-hole reverse fix variants and G125-MH11605M4R for right-angle screw-lock options. Cross-series replacements require careful verification of pitch, current ratings, and mechanical dimensions to ensure functional equivalence.
