G125-MV12605M3R

Overview

The G125-MV12605M3R is a vertical male header connector from the Harwin Gecko-SL series, designed for power-to-board applications. It features a 26-position configuration with a 1.25 mm pitch and gold-plated phosphor bronze contacts rated for 2 A current. The component utilizes through-hole solder pin termination and includes screw fixings with 5 mm board mount studs for secure attachment. Operating within a temperature range of -65 °C to +150 °C, it offers high reliability in demanding environments.

Feature Summary

• Vertical male contact orientation for direct board mounting
• Integrated screw fixing mechanism with 5 mm board mount studs
• Gold-plated phosphor bronze contacts for corrosion resistance
• High-temperature polyamide housing with UL 94 V-0 flammability rating

Applications

• Industrial control systems requiring robust power connections
• Automotive electronics with high vibration exposure
• Medical equipment needing reliable signal integrity
• Telecommunications infrastructure power distribution

Procurement Notes

Verify RoHS compliance status and REACH SVHC declarations before procurement. Confirm that the specific ordering suffix matches the required contact count and packaging format. Ensure compatibility with existing PCB footprint dimensions and screw fixation hardware specifications. Check for any recent product change notifications affecting material composition or manufacturing origin.

Selection Notes

Select this connector when vertical mating is required alongside mechanical stability provided by screw fixings. The 1.25 mm pitch allows for dense circuit layouts while maintaining adequate spacing for higher voltage isolation. Verify that the 2 A current rating per contact aligns with the system's power distribution requirements and thermal management capabilities.

Part Context

This part belongs to the Harwin Gecko-SL family, known for high-reliability interconnect solutions. The series supports various configurations including surface mount and through-hole options. The Gecko-SL line emphasizes durability in harsh environments, making it suitable for critical infrastructure applications where connection failure is not an option.

Replacement Considerations

No officially confirmed substitute part numbers are available in public documentation. Direct replacements must match the 1.25 mm pitch, 26-position count, vertical orientation, and screw-fixing feature set. Cross-compatibility with other manufacturers' headers requires careful verification of mechanical and electrical parameters.
