Overview
The G125-MS15005L0P is a rectangular header connector from the Harwin Gecko-Latch series, designed for surface mount applications. It features a dual-row configuration with 50 positions (2x25) and a 1.25 mm pitch. The component utilizes male pin contacts plated with gold over phosphor bronze, housed in black and green polyamide insulation. Rated for 2 A current and 250 V voltage, it operates within a temperature range of -65°C to +150°C. The straight solder pin termination ensures secure PCB attachment.
Feature Summary
- Gecko-Latch mechanical retention system for secure mating
- Surface mount straight termination style
- Dual-row 50-position layout with 1.25 mm spacing
- Gold-plated male pin contacts
Applications
- High-density board-to-board interconnects
- Industrial control module connections
- Automotive electronic subsystem linking
- Telecommunications equipment backplanes
Procurement Notes
Verify the specific suffix 'L0P' against the manufacturer datasheet to confirm housing color and packaging details. Ensure the ordering code matches the required 50-position count and surface mount orientation. Confirm RoHS compliance status through official documentation before procurement.
Selection Notes
Select this part for applications requiring high contact density in a small footprint. The 1.25 mm pitch allows for compact designs compared to standard 2.54 mm headers. Verify that the PCB land pattern supports the 2x25 SMT configuration and that the mating connector accommodates the Gecko-Latch mechanism.
Part Context
This component belongs to the Harwin Gecko-Latch family, which emphasizes reliable mechanical locking. The G125 series offers various configurations including cable assemblies and vertical headers. This specific model provides a robust solution for permanent or semi-permanent board connections in space-constrained environments.
Replacement Considerations
Direct substitutes must match the 1.25 mm pitch, 2x25 position count, and SMT mounting style. Verify compatibility with the Gecko-Latch retention mechanism if replacing with non-Harwin parts. Check that alternative connectors support the same 2 A current rating and operating temperature range.
