G125-MS12605M2P

Overview

The G125-MS12605M2P is a Gecko-SL series male header connector manufactured by Harwin Inc. It features a 26-position, dual in-line configuration with a 1.25 mm pitch and 2-row arrangement. Designed for surface mount technology, this component utilizes gold-plated phosphor bronze contacts to ensure reliable signal transmission. The housing is constructed from green polyamide (PA) material, providing structural integrity and insulation. Rated for 2 A current per contact and operating within a temperature range of -65°C to +150°C, it supports vertical board mounting with screw fixings and 5 mm board mount studs.

Feature Summary

• Dual in-line male pin configuration for high-density interconnect applications
• Screw-fixing mechanism with integrated board mount studs for secure mechanical attachment
• Gold-plated contacts on phosphor bronze substrate for enhanced conductivity and corrosion resistance
• Polyamide housing rated UL 94 V-0 for flame retardancy and thermal stability

Applications

• Industrial control system backplanes
• Data center server blade interconnects
• Aerospace avionics wiring harnesses
• Power distribution units requiring robust surface mounting

Procurement Notes

Verify the specific suffix '2P' against the official Harwin datasheet to confirm the exact packing method and reel specifications. Ensure that the required board thickness accommodates the 5 mm stud height for proper screw fixation. Cross-reference the RoHS compliance status with the latest environmental declaration provided by the manufacturer prior to final procurement authorization.

Selection Notes

Select this component when a secure, mechanically locked surface mount connection is required for 26-position signals. The Gecko-SL series offers superior retention compared to standard SMT headers due to the screw-lock feature. Ensure the mating counterpart matches the 1.25 mm pitch and female socket type. Consider the vertical profile constraints imposed by the 4.90 mm insulation height during PCB layout planning.

Part Context

This part belongs to the Harwin Gecko-SL family, which specializes in high-reliability connectors for demanding environments. The series distinguishes itself through a unique locking mechanism that prevents accidental disconnection. The G125-MS12605M2P represents the male header variant designed specifically for surface mount integration, complementing the broader ecosystem of Gecko-SL power and signal solutions.

Replacement Considerations

No public confirmed substitute part numbers are available in the source documentation. Direct replacement requires matching the 1.25 mm pitch, 26-position count, dual row layout, and screw-lock mounting style. Verify compatibility with existing PCB footprints and mating housing dimensions before considering alternative manufacturers.
