G125-FV15005F1R

Overview

The G125-FV15005F1R is a Gecko-SL series female vertical printed circuit tail connector manufactured by Harwin Inc. It features a 1.25 mm pitch and provides 50 positions arranged in two rows. The component utilizes gold-plated copper alloy contacts housed in green nylon insulation, rated for 2 A current and 250 V voltage. Designed for through-hole mounting with a straight orientation, it operates within a temperature range of -65 °C to +150 °C and offers an insulation resistance of 10 GOhms.

Feature Summary

• Features a high-reliability design supporting up to 1000 mating cycles.
• Incorporates a threaded locking mechanism for secure connection retention.
• Provides polarized keying to ensure correct alignment during assembly.

Applications

• High-density board-to-board interconnections
• Signal transmission in compact electronic modules
• Power distribution in space-constrained assemblies

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm exact pin count, housing material, and termination style. Ensure compatibility with mating male headers from the same Gecko-SL family. Confirm that the vertical PCB tail configuration matches the target board layout requirements before finalizing procurement.

Selection Notes

Select this component when a robust, vertically oriented female connector is required for dense signal or power routing. The 1.25 mm pitch allows for high I/O counts in limited areas. Consider the 2 A per contact rating for electrical load capacity and verify that the operating temperature range meets the environmental conditions of the intended application.

Part Context

This part belongs to the Harwin Gecko-SL series, which focuses on high-reliability interconnect solutions. The series is characterized by its durability and compact form factor, suitable for demanding industrial and commercial applications where consistent performance over repeated mating cycles is critical.

Replacement Considerations

Compatible mating components include male headers such as G125-MV15005M2P and G125-MV15005M1P. Verify that substitute parts maintain the identical 1.25 mm pitch and 50-position configuration to ensure mechanical and electrical interchangeability.
