Overview
The G125-MS10605M3R is a 6-position male header connector from the Harwin Gecko-SL series. It features a 1.25 mm pitch and a 2x3 row configuration designed for surface-mount technology (SMT) applications. The component utilizes reverse fix mounting orientation with solder pin termination. Electrical specifications include a current rating of 2 A and voltage ratings of 250 V or 450 V. The contacts are made of phosphor bronze with gold plating, housed in green polyamide (PA). Operating temperature ranges from -65°C to +150°C, with UL 94 V-0 flammability rating.
Feature Summary
- Reverse fix surface-mount design for optimized PCB layout flexibility
- Jackscrew locking mechanism ensures secure mating stability
- Gold-plated phosphor bronze contacts for reliable signal transmission
Applications
- Industrial control systems requiring compact power connections
- Automotive electronics with space-constrained board designs
- Consumer devices needing high-density interconnects
Procurement Notes
Verify the specific suffix 'M3R' against official Harwin documentation to confirm the reverse fix SMT variant. Ensure compatibility with automated pick-and-place equipment due to the tape-and-reel packaging format. Cross-reference insulation resistance and dielectric strength values with the latest datasheet revision before finalizing procurement specifications.
Selection Notes
Select this component when a low-profile, right-angle-free SMT header is required. The 1.25 mm pitch allows for dense circuit layouts compared to standard 2.54 mm connectors. Consider the reverse fix feature if board clearance constraints prevent traditional vertical mounting orientations. Validate thermal performance within the specified -65°C to +150°C range for the intended operating environment.
Part Context
This part belongs to the Harwin Gecko-SL family, known for robust mechanical locking and compact form factors. The G125 series specifically targets high-reliability applications in automotive and industrial sectors. As a male header, it mates with corresponding female sockets to establish electrical pathways on printed circuit boards.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific reverse-fix SMT variant. Generic 1.25 mm headers may fit mechanically but lack the jack screw locking and reverse fix features. Verify pinout and housing dimensions carefully if considering alternative manufacturers.
