G125-FV12005F1R

Overview

The Harwin G125-FV12005F1R is a Gecko-SL series power-to-board connector designed for high-density applications. It features a 1.25 mm pitch and a 3.0 mm row spacing, accommodating 20 positions in a dual-row configuration. The component utilizes female socket contacts with a 2 A current rating per contact and a 250 V voltage rating. Constructed with gold-plated copper alloy contacts and nylon housings, it supports vertical through-hole solder pin termination. The unit operates within a temperature range of -65°C to +150°C.

Feature Summary

• Patented four-finger copper alloy contact design ensures reliable performance under extreme vibration conditions.
• Low-profile miniature package architecture provides significant space savings compared to Micro-D connectors.
• High-reliability construction enables stable operation across wide temperature ranges and harsh environments.

Applications

• Demanding electronic product designs requiring high reliability
• Space-constrained circuit board interconnections
• Applications subject to extreme vibration environments

Procurement Notes

Verify the specific ordering suffix against official datasheets to confirm exact pin count, housing material, and termination style. Ensure compatibility with mating male counterparts within the same Gecko-SL family. Confirm RoHS and REACH compliance status via manufacturer documentation prior to integration.

Selection Notes

Select this component when a compact, high-reliability solution is required for vertical board mounting. The 1.25 mm pitch allows for higher density than larger pitch alternatives. Verify that the 2 A current rating meets the specific circuit requirements and that the through-hole footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the Harwin Gecko-SL family, which focuses on delivering high performance in miniature packages. The series is engineered for demanding applications where standard connectors may fail due to size or environmental stress. The G125 designation indicates the 1.25 mm pitch characteristic of this specific line.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided data. Cross-model replacement requires verification of mechanical dimensions, electrical ratings, and mating interface compatibility with existing system components.
