Overview
The Harwin G125-MH25005L7P is a Gecko-Latch series board-to-board connector designed for surface-mount technology. It features a male pin configuration with a 1.25 mm pitch and two rows of contacts, totaling 50 positions. The component utilizes phosphor bronze contacts with gold plating and a polyamide 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 straight installation style ensures reliable vertical connection on printed circuit boards.
Feature Summary
- Gecko-Latch mechanism provides secure horizontal locking for SMT assembly
- High-reliability construction with gold-plated phosphor bronze contacts
- Polyamide insulation material supports high-temperature operation up to 150°C
Applications
- High-density board-to-board interconnections in embedded systems
- Surface-mount assembly requiring secure mechanical latching
- Industrial electronics operating in extreme temperature environments
Procurement Notes
Verify the specific suffix 'L7P' against official Harwin documentation to confirm the exact housing height and locking mechanism specifications. Ensure compatibility with mating female connectors from the same Gecko-Latch family. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before procurement.
Selection Notes
Select this part when a surface-mount male header with integrated latching is required for 50-position connections. The 1.25 mm pitch allows for dense packing while maintaining electrical isolation. Consider the straight orientation and SMT mounting style for automated placement processes. Verify that the 2 A current rating meets the application's power distribution requirements.
Part Context
This component belongs to the Harwin Gecko G125 series, which specializes in high-reliability interconnects. The series offers various configurations including latchable options for enhanced mechanical stability during thermal cycling. The G125-MH25005L7P represents a specific variant optimized for surface-mount applications requiring robust retention forces.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Direct replacement requires identical pitch, row count, and latching mechanism specifications from the same manufacturer or compatible third-party equivalents.
