G125-MH12005L3P

Overview

The Harwin G125-MH12005L3P is a Gecko-Latch male header connector featuring a 1.25 mm pitch and 20 positions in a dual-row configuration. It utilizes right-angle through-hole solder pin termination with a 3.3 mm contact length. The housing is constructed from green nylon with UL 94 V-0 flammability rating, while phosphor bronze contacts are gold-plated. Rated for 2 A current and 250 V voltage, it operates within a temperature range of -65°C to +150°C.

Feature Summary

• Gecko-Latch series design provides horizontal PCB hold-down functionality without integrated locking mechanisms
• Shrouded four-wall construction ensures precise wire-to-board alignment and protection
• Gold-plated phosphor bronze contacts support reliable signal transmission in high-density applications

Applications

• Wire-to-board interconnections in compact electronic assemblies
• Signal routing in industrial control modules requiring right-angle mounting
• Consumer electronics utilizing dense multi-pin connection requirements

Procurement Notes

Verify the specific suffix 'L3P' against official Harwin documentation to confirm the absence of latches and the presence of board lock features. Ensure compatibility with mating cables and verify that the 3.3 mm tail length aligns with target PCB thickness constraints before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, right-angle male header is required for space-constrained designs. The 1.25 mm pitch allows for high pin counts in small footprints. Consider the lack of latches if vibration resistance is not a primary concern, or opt for latch-equipped variants if mechanical retention during mating cycles is critical.

Part Context

This part belongs to the Harwin Gecko-Latch family, designed for micro-miniature applications. The G125 series emphasizes compactness and reliability, offering various termination styles and row configurations. This specific model represents a standard horizontal male header variant within the broader Gecko ecosystem.

Replacement Considerations

Direct substitutes include other Harwin Gecko-Latch headers with identical 1.25 mm pitch and 20-position layout, such as G125-MH12005L5P, provided the locking mechanism differences are acceptable. Cross-brand replacements require matching pitch, current ratings, and physical dimensions.
