G125-MS12005L0P

Overview

The Harwin G125-MS12005L0P is a Gecko-Latch series power-to-board connector designed for surface mount technology. It features a male pin configuration with a 1.25 mm pitch and two rows of ten positions, totaling twenty contacts. The housing is constructed from green polyamide (PA) material, while the phosphor bronze contacts are gold-plated to ensure reliable conductivity. Rated for 2 A current and voltages up to 250 V or 450 V, this straight-mount header operates within a temperature range of -65 C to +150 C. It offers an insulation resistance of 10 GOhms and utilizes a solder termination type for secure PCB attachment.

Feature Summary

• Gecko-Latch mechanical locking system ensures secure mating engagement
• Surface mount design facilitates automated pick-and-place assembly
• High-temperature polyamide housing supports demanding thermal environments

Applications

• Industrial control systems requiring compact power distribution
• Automotive electronics utilizing high-density interconnects
• Telecommunications infrastructure equipment
• Medical device internal power connections

Procurement Notes

Verify the specific suffix L0P against official Harwin documentation to confirm tape and reel packaging requirements. Ensure compatibility with standard SMT reflow profiles. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, high-reliability power connection is required on dense PCB layouts. The 1.25 mm pitch allows for significant contact density compared to larger spacing options. Consider the Gecko-Latch feature if vibration resistance and positive mating feedback are critical for the application environment.

Part Context

This part belongs to the Harwin G125 Gecko-Latch family, which specializes in high-performance power connectors. The series is known for its robust mechanical latching mechanism and suitability for harsh industrial conditions. It complements other variants in the lineup that offer different pin counts, orientations, and termination styles.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, 2x10 position count, and Gecko-Latch locking mechanism. Verify that alternative headers maintain identical voltage and current ratings alongside compatible surface mount footprints to ensure seamless integration without PCB redesign.
