G125-FV11005L0P

Overview

The Harwin G125-FV11005L0P is a Gecko-Latch series rectangular connector designed for power-to-board applications. It features a 1.25 mm pitch with a 2x3 pin configuration, totaling six positions. The component utilizes female socket contacts and is intended for vertical through-hole mounting. Electrical specifications include a current rating of 2 A and voltage ratings of 250 V or 450 V. The operating temperature range spans from -65°C to +150°C.

Feature Summary

• Vertical through-hole mounting style for direct PCB integration
• Gecko-Latch mechanical locking system for secure connection retention
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Polyamide (PA) housing material providing thermal stability

Applications

• Industrial control systems requiring robust power connections
• Automotive electronics modules needing high-temperature resistance
• Consumer appliance mainboards utilizing compact power interfaces
• Telecommunications equipment power distribution units

Procurement Notes

Verify the specific datasheet version to confirm insulation resistance values and compliance certifications such as RoHS and REACH. Ensure the selected variant matches the required contact plating thickness and housing color coding if applicable. Cross-reference the official Harwin ordering suffixes to confirm exact packaging and terminal type specifications before finalizing procurement orders.

Selection Notes

Select this component when a low-profile vertical connector with a 1.25 mm pitch is required for space-constrained designs. The Gecko-Latch mechanism provides superior retention force compared to standard headers. Verify that the board layout accommodates the specific through-hole pad dimensions and that the 2 A current rating meets the circuit load requirements without derating issues at elevated temperatures.

Part Context

This part belongs to the Harwin Gecko-Latch family, which emphasizes secure mating and high reliability in harsh environments. The G125 series offers a compact footprint suitable for modern electronics. This specific model represents a female receptacle variant, complementing male header counterparts within the same ecosystem to ensure consistent mechanical and electrical performance across assemblies.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Compatible alternatives must match the 1.25 mm pitch, 2x3 configuration, vertical orientation, and through-hole termination. Verify that any replacement maintains equivalent voltage ratings and locking mechanisms to ensure functional interchangeability.
