G125-FS15005F1R

Overview

The G125-FS15005F1R is a Gecko-SL series rectangular connector manufactured by Harwin Inc. It features a 1.25mm pitch and consists of 50 positions arranged in two rows. The component utilizes female socket contacts with gold plating for reliable signal transmission. Designed for surface-mount technology (SMT), it offers a low-profile form factor suitable for space-constrained applications. The connector supports a rated current of 2A per contact and operates within a temperature range of -65°C to +150°C.

Feature Summary

• Low-profile design optimized for high-density mounting
• Patented four-finger copper alloy contact structure for enhanced reliability
• Threaded locking mechanism ensures secure connection under vibration
• Gold-plated contacts provide corrosion resistance and stable conductivity

Applications

• Automotive electronic systems
• Industrial control equipment
• General purpose interconnect solutions

Procurement Notes

Verify the specific suffix and packaging configuration against the official Harwin datasheet to ensure compatibility with automated assembly processes. Confirm that the surface-mount footprint matches the target PCB layout dimensions. Check for RoHS compliance status relevant to the manufacturing region. Ensure the selected variant meets the required thermal and mechanical stress specifications for the intended operational environment.

Selection Notes

Select this component when a high-reliability, compact interconnect solution is required for harsh environments. The 1.25mm pitch allows for significant space savings compared to larger pitch connectors. Consider the threaded locking feature if the application involves high vibration or shock loads. Verify that the 2A current rating per contact aligns with the circuit requirements.

Part Context

This part belongs to the Harwin Gecko family, which is engineered for demanding applications requiring high performance in miniature packages. The G125 series provides a 35% space saving over comparable Micro-D connectors. The family is known for its ability to withstand extreme conditions, including wide temperature ranges and high G-force vibrations, making it suitable for robust industrial and automotive deployments.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-reference with other Gecko-SL variants only if pin count, pitch, and termination type match exactly. Consult Harwin engineering for potential obsolescence management or alternative sourcing strategies.
