G125-FV25005L0P

Overview

The Harwin G125-FV25005L0P is a Gecko-Latch series power-to-board connector designed for vertical through-hole mounting. It features a 1.25 mm pitch and a 2-row configuration with 50 positions. The component utilizes female socket contacts plated with gold, housed in polyamide (PA) insulation. Electrical ratings include a current capacity of 2 A and a voltage rating of 450 V. The unit operates within a temperature range of -65°C to +150°C and exhibits an insulation resistance of 10 GOhms.

Feature Summary

• Vertical through-hole solder pin termination for secure board attachment
• Gold-plated female socket contacts ensuring reliable signal transmission
• Polyamide housing material providing thermal stability up to 150°C

Applications

• High-density power distribution systems
• Industrial control board interconnections
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific contact count and row configuration against the official datasheet before ordering, as the Gecko-Latch series offers various position options. Confirm that the 450 V voltage rating and 2 A current limit align with the target circuit requirements. Ensure compatibility with standard lead-free soldering processes if RoHS compliance is mandatory for the assembly line.

Selection Notes

Select this component when a high-pin-count vertical interface is required for space-constrained designs. The 1.25 mm pitch allows for dense routing compared to larger spacing standards. Consider the 10 GOhms insulation resistance for applications requiring strict isolation. Verify that the polyamide housing meets the environmental exposure conditions of the final product deployment.

Part Context

This part belongs to the Harwin Gecko-Latch family, which specializes in compact, high-reliability interconnect solutions. The series is engineered for demanding environments where vibration resistance and stable electrical performance are critical. The G125-FV25005L0P represents a high-position variant within the vertical header segment, suitable for complex power architectures.

Replacement Considerations

Cross-reference with other Harwin Gecko-Latch vertical headers such as G125-FV23405L0P or G125-FV22005L0P for lower pin counts. Ensure any substitute maintains the identical 1.25 mm pitch and 2-row layout to preserve PCB footprint compatibility.
