G125-MS12005M1R

Overview

The G125-MS12005M1R is a Gecko-SL series power-to-board connector manufactured by Harwin. It features a 1.25 mm pitch, 20-position (2x10) male header configuration with straight surface mount terminals. Rated for 2 A current and 250 V/450 V voltage, it utilizes phosphor bronze contacts with gold plating. The housing is constructed from polyamide (PA), offering an operating temperature range of -65°C to +150°C and insulation resistance of 10 GOhms. Packaged in tape and reel format, this component supports automated pick-and-place assembly.

Feature Summary

• Gecko-SL design enables automated pick-and-place manufacturing processes
• Integrated mating flange provides mechanical stability during assembly
• Polarizing key ensures correct orientation and prevents misalignment

Applications

• Automated surface mount technology (SMT) production lines
• High-density power distribution on printed circuit boards
• Compact electronic assemblies requiring reliable vertical interconnects

Procurement Notes

Verify the specific suffix M1R against official Harwin documentation to confirm tape and reel packaging and polarizing key inclusion. Ensure compatibility with standard SMT reflow profiles and check RoHS compliance status via the manufacturer's latest datasheet before integration into final designs.

Selection Notes

Select this component when high-volume automated assembly is required for power-to-board connections. The Gecko-SL variant specifically addresses throughput needs through pick-and-place capability. Verify that the 1.25 mm pitch and 20-position layout match the target PCB footprint and that the 2 A current rating suffices for the application load.

Part Context

This part belongs to Harwin’s G125 Gecko family, designed for compact power applications. The MS12005 designation indicates a 2x10 position male header with a 1.25 mm pitch. The M1R suffix typically denotes specific packaging or feature variations within the Gecko-SL line, distinguishing it from standard bulk or cut-tape variants.

Replacement Considerations

Direct substitutes within the same Gecko-SL series include G125-MS12005L3R, which shares similar electrical ratings but may differ in locking mechanisms or packaging. Cross-series replacements require careful verification of pitch, contact count, and mounting style to ensure mechanical and electrical compatibility.
