G125-MS12005L2R

Overview

The Harwin G125-MS12005L2R is a Gecko series power-to-board connector featuring a 1.25 mm pitch and 20 positions in a dual-row configuration. Designed for surface-mount technology, it utilizes male pin contacts made of phosphor bronze with gold plating. The unit supports a current rating of 2 A and voltage ratings of 250 V or 450 V. It operates within a temperature range of -65°C to +150°C and includes board lock features. The housing is constructed from green polyamide (PA) material.

Feature Summary

• Vertical surface-mount design for compact PCB integration
• Board lock mechanism ensures secure mating stability
• Gold-plated phosphor bronze contacts for reliable conductivity
• High-temperature polyamide housing for thermal resilience

Applications

• Industrial control systems requiring robust power distribution
• Automotive electronics utilizing high-temperature connectors
• Consumer appliances needing compact power interfaces
• Telecommunications equipment with space-constrained layouts

Procurement Notes

Verify the specific suffix 'L2R' confirms tape-and-reel packaging rather than cut tape or tray formats. Ensure compatibility with existing Gerber files regarding SMT footprint dimensions. Confirm that the 1.25 mm pitch aligns with the target PCB silkscreen and copper pad specifications to prevent soldering defects during assembly processes.

Selection Notes

Select this component when vertical mounting and high-density power delivery are required. The 1.25 mm pitch allows for significant pin count in limited areas. Verify that the 2 A per contact rating meets the circuit load requirements. Consider the operating temperature range if the environment exceeds standard commercial limits.

Part Context

This part belongs to the Harwin Gecko family, known for high-density interconnect solutions. The G125 series specifically targets applications demanding reliability in harsh environments. The MS designation indicates male pins, while the L2R suffix typically denotes reel packaging for automated assembly lines.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, 2x10 position layout, and vertical SMT form factor. Verify that alternative brands offer comparable current ratings and temperature tolerances. Ensure mechanical locking features are compatible to maintain assembly integrity.
