G125-FV21205L0P

Overview

The G125-FV21205L0P is a female vertical through-board connector from the Harwin Gecko-SL series. It features a 1.25 mm pitch and a 2x5 position configuration, totaling ten contacts. The component utilizes gold-plated copper alloy sockets for reliable signal transmission. Designed for surface-mount or through-hole integration, it supports a rated current of 2 A and a voltage rating of 250 V. The operating temperature range spans from -65 °C to +150 °C. The housing is constructed from green nylon, providing mechanical stability and insulation.

Feature Summary

• Vertical orientation design facilitates compact board stacking
• Gold-plated contact surfaces ensure durable electrical connectivity
• Integrated latch mechanism secures mating connections

Applications

• Industrial control system interconnects
• Automotive electronic module power distribution
• Telecommunications equipment backplanes

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm pin count, pitch, and termination style. Ensure compatibility with mating male headers within the same Gecko-SL family. Confirm RoHS compliance status and lead times directly with authorized distributors prior to procurement.

Selection Notes

Select this component when a low-profile vertical interface is required for high-density applications. The 1.25 mm pitch allows for significant I/O density in constrained spaces. Verify that the 2 A current rating meets the circuit requirements. Consider the thermal limits of the nylon housing when designing for high-temperature environments.

Part Context

This part belongs to the Gecko-SL series, characterized by its slim profile and secure latching system. The series is engineered for demanding environments requiring robust mechanical retention and reliable electrical performance. The vertical form factor distinguishes it from horizontal variants, optimizing space utilization on printed circuit boards.

Replacement Considerations

Compatible substitutes include other Harwin Gecko-SL series connectors with matching 1.25 mm pitch and 2x5 positioning. Ensure the replacement maintains the same vertical orientation and female socket configuration. Cross-reference mating male parts to guarantee mechanical fit and electrical continuity.
