G125-MV12005M3R

Overview

The G125-MV12005M3R is a male header from the Harwin Gecko-SL series, designed for power-to-board applications. It features a 1.25 mm pitch and a 2x10 position configuration (20 total positions). The connector utilizes a vertical orientation with reverse fix mounting style and through-hole solder pin termination. Constructed with phosphor bronze contacts featuring gold plating, it supports a current rating of 2 A per contact. The housing is made of polyamide, rated UL 94 V-0, and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions.
• Jackscrew locking mechanism provides secure mating stability in demanding environments.
• Compact low-profile form factor achieves significant space savings compared to larger high-performance connectors.

Applications

• Power distribution modules requiring robust board-to-board connections
• Industrial control systems operating in high-vibration zones
• Automotive electronics subject to wide thermal fluctuations

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm that the specific suffix matches the required reverse fix vertical configuration. Ensure compatibility with mating female housings from the same Gecko-SL family. Validate RoHS compliance status through current documentation as product lifecycle status may affect availability.

Selection Notes

Select this part when vertical power delivery is required alongside high mechanical stability. The jack-screw feature distinguishes it from standard press-fit or snap-lock headers. Consider the 1.25 mm pitch constraints for PCB trace routing. Verify that the 2 A current rating meets the specific circuit load requirements without derating issues.

Part Context

This component belongs to the G125 Gecko-SL family, characterized by its 1.25 mm pitch and high-reliability engineering. The series is engineered for miniature packaging while maintaining performance in extreme temperatures and vibration. The MV variant specifically denotes vertical male headers with distinct fixing mechanisms suitable for power applications.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.25 mm pitch, 2x10 position count, vertical orientation, and jack-screw locking type. Cross-reference with other Harwin G125 variants only if mechanical and electrical specifications align exactly.
