G125-MH22005L7P

Overview

The G125-MH22005L7P is a Gecko-Latch series header manufactured by Harwin Inc. It features a 1.25 mm pitch and 20 positions arranged in a dual-row configuration. The component utilizes male pin contacts with gold plating on phosphor bronze substrates. Designed for surface-mount technology, it offers a horizontal installation style with solder pin termination. The housing is constructed from nylon material, providing UL 94 V-0 flammability rating. Electrical ratings include a current capacity of 2 A per contact and an insulation resistance of 1 GOhm. Operating temperatures range from -65°C to +150°C.

Feature Summary

Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions.
Low-profile shrouded housing minimizes board space requirements while maintaining secure mating.
Horizontal surface-mount orientation facilitates compact circuit board layouts.

Applications

Wire-to-board interconnections
Power to the board connections
High-reliability electronic assemblies

Procurement Notes

Verify the specific suffix L7P against official Harwin documentation to confirm exact mechanical dimensions and locking mechanism specifications. Ensure compatibility with corresponding female housings within the Gecko-Latch family. Confirm RoHS compliance status through the manufacturer's latest technical resources before integration into production designs.

Selection Notes

Select this component when horizontal surface-mount mounting is required for 1.25 mm pitch applications. Consider the 20-position count and dual-row layout for density needs. Validate that the 2 A current rating and temperature range meet system operational requirements. Ensure PCB footprint matches the specified SMT pad arrangement.

Part Context

This part belongs to the Harwin Gecko-Latch family, designed for demanding environments requiring high performance in miniature packages. The series offers significant space savings compared to larger pitch connectors. It is engineered to withstand Z-axis vibrations up to 100g at 6m/s, ensuring stability in harsh operating conditions.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other Harwin G125 series variants only if mechanical and electrical parameters match exactly.
