Overview
The Harwin G125-MS15005L0R is a Gecko-Latch series power-to-board connector featuring a 1.25 mm pitch and vertical surface mount termination. It provides a 2x25 position configuration with phosphor bronze contacts gold-plated for conductivity. Rated for 2 A current and 250 V/450 V voltage, it operates within a -65 C to +150 C range. The polyamide housing ensures high insulation resistance of 10 GOhms, supporting reliable electrical connections in compact board layouts.
Feature Summary
- Vertical surface mount design for space-efficient PCB integration
- Gecko-Latch mechanism ensures secure mating retention
- Gold-plated phosphor bronze contacts for reliable signal integrity
- Polyamide housing material for thermal stability
Applications
- Compact power distribution modules
- Industrial control board interconnects
- Telecommunications equipment backplanes
- Automotive electronics power interfaces
Procurement Notes
Verify the specific suffix L0R against official datasheets to confirm orientation and packaging details. Ensure compatibility with mating sockets from the same Gecko-Latch family. Check RoHS compliance status via manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component when vertical SMT mounting is required for high-density power applications. Confirm that the 1.25 mm pitch matches existing board layout constraints. Validate that the 2 A current rating meets system load requirements without derating issues.
Part Context
This part belongs to the Harwin Gecko-Latch family, designed for robust power-to-board connections. It complements other Gecko-SL and standard Gecko headers by offering latch-based retention. The series supports various positions and orientations for diverse electronic assembly needs.
Replacement Considerations
Direct substitutes are limited due to proprietary latch mechanisms. Verify cross-compatibility only with matching Gecko-Latch series sockets. Generic 1.25 mm headers lack equivalent retention features.
