G125-MH15005L5R

Overview

The Harwin G125-MH15005L5R is a Gecko-Latch series male header connector designed for power-to-board applications. It features a 1.25 mm pitch with 50 positions arranged in two rows. The component utilizes phosphor bronze contacts with gold plating and a polyamide (PA) housing. Rated for 2 A current and 250 V/450 V voltage, it operates within a temperature range of -65°C to +150°C. The connector employs board lock mounting with a right-angle orientation and solder pin termination.

Feature Summary

• Gecko-Latch mechanical locking system ensures secure connection under extreme vibration conditions.
• Patented four-finger copper alloy contact design provides high reliability and low insertion force.
• Board lock mechanism secures the connector to the PCB without requiring additional fasteners.
• Shrouded design protects contacts and prevents misalignment during mating.

Applications

• High-reliability industrial equipment requiring robust board-to-board connections
• Aerospace and defense systems operating in extreme environmental conditions
• Automotive electronics subject to high vibration and thermal stress

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration against official Harwin documentation. Confirm that the part number corresponds to the right-angle, board-lock variant rather than standard through-hole versions. Ensure compatibility with mating sockets from the same Gecko-Latch family. Check RoHS compliance status directly on the manufacturer datasheet before procurement.

Selection Notes

Select this part when high-density 1.25 mm spacing is required alongside mechanical latching security. The right-angle form factor suits space-constrained vertical interconnects. Verify that the 2 A per contact rating meets circuit load requirements. Consider the polyamide housing material for thermal stability up to 150°C in demanding operational environments.

Part Context

This component belongs to the Harwin Gecko-Latch family, an evolution of the G125 series focused on enhanced mechanical retention. Unlike standard headers, the Latch variant integrates a locking feature to prevent accidental disengagement. It complements other G125 components like cable assemblies and female housings to form complete interconnect solutions.

Replacement Considerations

Direct substitutes include G125-MH15005L5P (cut tape vs. reel packaging difference). Cross-series replacements require verifying identical 1.25 mm pitch, 50-position count, and right-angle geometry. Ensure any alternative maintains the board-lock mounting style and Gecko-Latch interface compatibility.
