Overview
The Harwin G125-MH15005L3P is a Gecko-SL series male pin header featuring 50 positions in a dual-in-line configuration. It utilizes a 1.25 mm pitch with two rows and operates within a temperature range of -65°C to +150°C. The connector employs through-hole right-angle solder termination with gold-plated phosphor bronze contacts rated for 2 A current. Its green polyamide housing provides UL 94 V-0 flammability, while the jack-screw locking mechanism ensures secure board mounting.
Feature Summary
- Patented four-finger copper alloy contact design ensures high reliability under extreme vibration conditions up to 100g.
- Jack-screw locking system provides secure reverse fix and prevents accidental disconnection during operation.
- Low-profile shrouded construction offers significant space savings compared to standard high-performance connectors.
Applications
- High-reliability board-to-board interconnects
- Cable assemblies requiring robust mechanical retention
- Electronics operating in environments with extreme vibration
Procurement Notes
Verify that the specific suffix L3P corresponds to the required 3.3mm tail length and horizontal orientation. Confirm compatibility with mating female sockets from the same Gecko-SL family. Ensure PCB layout accommodates the right-angle footprint and through-hole soldering requirements specified in the official datasheet.
Selection Notes
Select this component when high-density connections are required alongside superior mechanical stability. The 1.25 mm pitch allows for compact designs without sacrificing current capacity. The jack-screw feature is essential for applications where vibration resistance and secure locking are critical performance factors.
Part Context
This part belongs to the Harwin Gecko-SL family, designed for demanding industrial and commercial applications. The series emphasizes miniaturization and durability, utilizing patented contact technology to maintain performance in harsh environments including wide temperature extremes and high-g vibration scenarios.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the 1.25 mm pitch, 50-position count, right-angle orientation, and jack-screw locking mechanism specifications.
