G125-MH21205L2P

Overview

The Harwin G125-MH21205L2P is a Gecko-Latch series header connector designed for board-to-board or cable applications. It features a 1.25 mm (0.049 in) pitch with two rows and six positions, totaling twelve contact points. The component utilizes male pin contacts made of phosphor bronze with gold plating, rated for 2 A current and 250 V voltage. Designed for surface mount installation, it offers a shrouded four-wall housing to ensure alignment and protection. The connector operates within a temperature range of -65°C to +150°C and meets UL 94 V-0 flammability standards.

Feature Summary

• Gecko-Latch mechanical locking system ensures secure mating retention
• Shrouded four-wall housing design provides precise alignment and environmental protection
• Gold-plated phosphor bronze contacts support reliable signal transmission
• Surface mount termination facilitates automated PCB assembly processes

Applications

• Board-to-board interconnections requiring high density
• Cable-to-board connections in compact electronic modules
• Industrial control systems operating in extreme temperatures
• Automotive electronics demanding robust mechanical retention

Procurement Notes

Verify the specific suffix configuration against official Harwin documentation to confirm orientation and locking mechanism details. Ensure compatibility with surface mount reflow profiles and check for RoHS compliance status prior to integration. Cross-reference the datasheet for exact dimensional tolerances and soldering recommendations to prevent mechanical stress during operation.

Selection Notes

Select this model when a low-profile, high-density connection with positive latching is required. The 1.25 mm pitch allows for compact circuit layouts while maintaining adequate spacing. Consider the surface mount footprint and the need for shrouded alignment in tight spaces. Evaluate thermal requirements against the specified operating range and insulation material properties.

Part Context

This component belongs to the Harwin Gecko-Latch family, known for its micro-miniature form factor and secure locking capabilities. The series is engineered for high-reliability applications where vibration resistance and precise mating are critical. The G125 designation indicates the specific pitch and housing style within the broader product portfolio.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires identical pitch, row count, and mounting type specifications from compatible manufacturers.
