G125-FV21205L0R

Overview

The G125-FV21205L0R is a Gecko-SL series power-to-board connector manufactured by Harwin Inc. It features a vertical surface-mount design with a 1.25 mm pitch and 12 positions (2x6). Rated for 2 A current and 250 V voltage, it utilizes gold-plated phosphor bronze contacts within a green polyamide housing. The component operates between -65°C and +150°C and supports pick-and-place assembly via tape and reel packaging.

Feature Summary

Vertical surface-mount configuration optimized for automated pick-and-place manufacturing processes.
Gecko-SL locking mechanism ensures secure mating and reliable connection stability.
Gold-plated phosphor bronze contacts provide durable electrical conductivity and corrosion resistance.
Green polyamide insulation housing meets UL94 V-0 flammability standards.

Applications

Automotive electronic systems
General industrial equipment
Power distribution boards

Procurement Notes

Verify the specific suffix L0R against official datasheets to confirm tape and reel packaging requirements. Ensure compatibility with standard SMT reflow profiles and verify that the 1.25 mm pitch matches the target PCB footprint. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when a vertical, low-profile power connection is required for high-density board layouts. The 1.25 mm pitch allows for compact designs while maintaining robust 2 A current carrying capacity. Consider the Gecko-SL locking feature if vibration resistance is critical for the application environment.

Part Context

This part belongs to the Harwin Gecko-SL family of connectors, designed for demanding applications requiring high reliability. The series offers various configurations including headers, receptacles, and cable assemblies, all sharing a common 1.25 mm interface for system interoperability.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided data. Direct replacement requires matching the 1.25 mm pitch, 12-position count, vertical orientation, and Gecko-SL locking mechanism specifications.
