Overview
The G125-MS15005M3R is a Gecko-Latch series power-to-board connector header manufactured by Harwin Inc. It features a 50-position configuration with a 1.25 mm pitch arranged in two rows. The component utilizes male pin contacts made of phosphor bronze with gold plating, rated for 2 A current and 250 V/450 V voltage. Designed for surface mount (SMD/SMT) installation, it offers a straight mounting style and operates within a temperature range of -65°C to +150°C. The housing is constructed from polyamide (PA), providing UL 94 V-0 flammability rating and 10 GOhms insulation resistance.
Feature Summary
- Gecko-Latch jackscrew locking mechanism ensures secure mating and prevents accidental disconnection.
- Surface mount design facilitates automated pick-and-place assembly processes.
- Gold-plated phosphor bronze contacts provide reliable electrical performance and corrosion resistance.
Applications
- Industrial control systems requiring high-reliability board-to-board connections
- Telecommunications equipment utilizing surface-mounted power distribution
- Automotive electronics demanding robust signal integrity
Procurement Notes
Verify the specific ordering suffix to confirm the reel quantity and tape width specifications required for your assembly line. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance documentation relevant to your region's regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a high-density, vertically oriented surface mount header is required for power or signal transmission. Consider the 1.25 mm pitch and 50-position count against available PCB real estate. Evaluate the need for the integrated jackscrew locking feature versus other Gecko series variants that may offer different retention methods or mounting styles.
Part Context
This part belongs to the Harwin G125 Gecko-Latch family, designed for applications needing secure, vibration-resistant connections. It complements socket counterparts and cable assemblies within the same ecosystem, ensuring mechanical and electrical interoperability across the broader connector system architecture.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Cross-reference with other G125-MS series headers for similar pitch and position counts if exact replacement is unavailable.
