G125-FV12005L0P

Overview

The Harwin G125-FV12005L0P is a Gecko series power-to-board receptacle connector designed for vertical through-hole mounting. It features a 1.25 mm (0.049 inch) pitch with 20 positions arranged in two rows. The connector utilizes phosphor bronze contacts with gold plating and a polyamide (PA) housing. Rated for 2 A current and 250 V voltage, it operates within a temperature range of -65°C to +150°C. The unit includes a pick-and-place cap for automated assembly.

Feature Summary

• Vertical through-hole receptacle design for board-to-board or wire-to-board connections
• Gold-plated phosphor bronze contacts ensure reliable signal transmission
• Integrated pick-and-place cap facilitates automated surface mount assembly processes

Applications

• Industrial control systems requiring high-density power distribution
• Automotive electronics modules needing robust vertical interconnects
• Consumer appliance mainboards utilizing compact power connectors

Procurement Notes

Verify the specific suffix configuration against the official datasheet to confirm contact count and orientation. Ensure compatibility with mating pins regarding current ratings and thermal limits. Confirm RoHS compliance status for the specific production batch. Check for availability of compatible mating hardware such as screws or latches if required by the mechanical design.

Selection Notes

Select this component when a vertical, non-latching receptacle is required for high-reliability power applications. The 1.25 mm pitch allows for dense packing while maintaining adequate spacing for higher currents. Consider the operating temperature range and voltage rating to ensure suitability for the target environment. Verify that the PCB layout supports the specified through-hole termination method.

Part Context

This part belongs to the Harwin Gecko G125 family, known for micro-miniature connectivity solutions. The series offers various configurations including latch and non-latch options. The FV suffix typically denotes a female vertical receptacle. This specific model provides a standard 2x10 configuration suitable for general power and signal routing in compact electronic assemblies.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, 20-position layout, and vertical through-hole form factor. Verify that alternative connectors support the same 2 A current rating and 250 V insulation voltage. Ensure mechanical dimensions are compatible with existing PCB footprints and enclosure constraints.
