G125-FS12605L0P

Overview

The Harwin G125-FS12605L0P is a Gecko series PCB receptacle featuring a 1.25 mm pitch and 20 contacts arranged in a dual-row configuration. Designed for surface mount technology, this female socket connector supports vertical board-to-board or power-to-board interconnections. It operates within a voltage range of up to 250 V and handles currents up to 2 A. The component utilizes gold-plated phosphor bronze contacts housed in green polyamide insulation, ensuring reliable performance across an operating temperature range from -65°C to +150°C.

Feature Summary

• Vertical surface mount design for compact PCB integration
• Gold-plated phosphor bronze contacts for enhanced conductivity
• Green polyamide housing providing thermal stability

Applications

• High-density electronic assemblies requiring vertical interconnects
• Power distribution modules in industrial equipment
• Consumer electronics with space-constrained layouts

Procurement Notes

Verify the specific contact count and row configuration against official datasheets, as distributor listings may contain conflicting information regarding pin counts. Confirm that the ordering suffix matches the required vertical orientation and surface mount termination style. Ensure compatibility with mating male headers before procurement.

Selection Notes

Select this component when a vertical, low-profile connection is required for dense circuit boards. The 1.25 mm pitch allows for high I/O density in limited spaces. Consider the 2 A current rating and 250 V voltage limit to ensure electrical safety margins are met for the specific application environment.

Part Context

This part belongs to the Harwin Gecko G125 family, which specializes in high-reliability connectors for demanding environments. The series offers various configurations including through-hole and cable assemblies, but this specific model focuses on surface mount receptacles for efficient automated assembly processes.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, 20-pin dual-row layout, and vertical SMT form factor. Verify that alternative manufacturers offer compatible gold plating thickness and polyamide housing materials to maintain thermal and electrical performance equivalence.
