G125-FS11605F3R

Overview

The Harwin G125-FS11605F3R is a 16-position, dual-row female socket connector from the Gecko-SL series. It features a 1.25 mm pitch and is designed for vertical surface-mount technology (SMT) applications. The component supports board-to-board or power-to-the-board connections with a rated voltage of 250 V and current capacity of 2 A. Contacts are made of beryllium copper with gold plating, housed in green nylon. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Vertical surface-mount design for compact PCB integration
• Gold-plated beryllium copper contacts ensure reliable signal integrity
• High-temperature resistant nylon housing for thermal stability
• Dual-row configuration maximizes connection density

Applications

• Board-to-board interconnects in dense electronic assemblies
• Power distribution modules requiring robust SMT mounting
• Industrial control systems operating in high-temperature environments
• Compact consumer electronics with space constraints

Procurement Notes

Verify that the specific suffix 'R' confirms the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with standard SMT reflow profiles and confirm that the 1.25 mm pitch aligns with the target PCB footprint design. Cross-reference the official datasheet for precise mechanical dimensions to avoid placement errors during manufacturing.

Selection Notes

Select this model when a vertical, surface-mount female connector is required for high-density layouts. The 1.25 mm pitch offers a balance between pin count and spacing. Consider the 2 A current rating and 250 V insulation for circuit requirements. The Gecko-SL series provides polarizing keys to prevent misalignment during mating.

Part Context

This part belongs to the Harwin Gecko-SL family, known for low-profile, high-reliability connectors. The series supports various configurations including through-hole and surface-mount options. The G125-FS variant specifically denotes a female socket designed for mating with corresponding male headers, ensuring secure electrical connections in demanding applications.

Replacement Considerations

Direct substitutes within the same series include G125-FS11605F3P (tray packaging) or G125-FS11605F3R variants with different contact counts. Verify mechanical compatibility before substitution. No cross-brand replacements are confirmed in public documentation.
