G125-MH11005L1P

Overview

The Harwin G125-MH11005L1P is a Gecko-Latch series header featuring 10 positions in a 2-row configuration with a 1.25 mm pitch. Designed for surface mount installation, it utilizes male pin contacts made of phosphor bronze with gold plating. The connector supports board-to-board or cable applications, rated for 2 A current and 450 VAC/DC voltage. It operates within a temperature range of -65°C to +150°C and uses UL94 V-0 polyamide insulation.

Feature Summary

• Integrated latching mechanism ensures secure mating retention
• Shrouded design provides four-wall protection against misalignment
• Surface mount termination facilitates automated PCB assembly

Applications

• Board-to-board interconnects
• Cable-to-board connections
• Industrial control systems
• Consumer electronics assemblies

Procurement Notes

Verify the specific suffix L1P confirms surface mount right-angle orientation and shrouded construction. Confirm that the Gecko-Latch locking feature matches the mechanical requirements of the target assembly. Ensure compatibility with standard reflow soldering profiles for surface mount components.

Selection Notes

Select this component when a low-profile, shrouded header with integrated mechanical locking is required. The 1.25 mm pitch suits dense layouts while maintaining adequate spacing. Verify that the 2 A rating aligns with the circuit's electrical load and that the operating temperature range covers environmental conditions.

Part Context

This part belongs to Harwin’s Gecko family, known for compact form factors and robust mechanical features. The Gecko-Latch variant specifically incorporates a screw-lock or latch system to prevent accidental disconnection, distinguishing it from standard unsecured headers in the same pitch series.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, 2x5 configuration, SMT right-angle mounting, and shrouded latching design. Generic equivalents may lack the specific Gecko-Latch retention mechanism.
