G125-FV13405L0R

Overview

The Harwin G125-FV13405L0R is a Gecko-Latch series power-to-board receptacle connector designed for vertical through-hole mounting. It features a 1.25 mm pitch and a 2x17 position configuration, totaling 34 contacts. The component utilizes female socket terminals with gold-plated beryllium copper contacts to ensure reliable signal integrity. Rated for 2 A current and 250 V voltage, it operates within a temperature range of -65 °C to +150 °C. The housing is constructed from nylon, providing mechanical stability in high-reliability applications.

Feature Summary

• Vertical through-hole design for direct PCB integration
• Gold-plated beryllium copper contacts for corrosion resistance
• Nylon housing material for structural durability
• Gecko-Latch series compatibility for secure mating

Applications

• High-reliability industrial power distribution systems
• Automotive electronic control unit interconnects
• Telecommunications infrastructure board-to-board connections
• Aerospace avionics power supply modules

Procurement Notes

Verify the specific ordering suffix L0R against official Harwin documentation to confirm tape-and-reel packaging requirements. Ensure that the selected variant matches the required contact count and pitch specifications for the target application. Cross-reference RoHS and REACH compliance status directly with the manufacturer's latest technical resources before finalizing procurement decisions.

Selection Notes

Select this component when a vertical orientation and 1.25 mm pitch are required for power-to-board interfaces. The Gecko-Latch series offers enhanced retention compared to standard headers. Confirm that the 2 A current rating and 250 V insulation voltage meet the circuit demands. Verify that the through-hole solder pin termination aligns with the manufacturing process capabilities of the assembly line.

Part Context

This part belongs to the Harwin Gecko G125 family, characterized by a 1.25 mm pitch and high-reliability standards. The series includes various male and female configurations for both wire-to-board and board-to-board applications. The Gecko-Latch sub-series specifically provides improved mechanical locking features to prevent accidental disconnection in vibration-prone environments.

Replacement Considerations

Direct substitutes within the same series include G125-FV13405L0P (bulk packaging) and G125-FV13405F1P (different contact count). Verify mechanical dimensions and electrical ratings before substitution. No cross-family replacements are recommended without full validation.
