G125-MV15005M3R

Overview

The Harwin G125-MV15005M3R is a power-to-board connector from the Gecko-SL series, designed for vertical through-hole mounting. It features a 1.25 mm pitch with a 2x25 position configuration (50 total). The male contacts are gold-plated phosphor bronze, rated for 2 A current and 450 V voltage. Operating temperature ranges from -65 °C to +150 °C. The housing is green polyamide (PA) with UL 94 V-0 flammability rating. Insulation resistance is 10 GOhms. It utilizes reverse fixings and supports pick-and-place tape & reel packaging.

Feature Summary

• Vertical through-hole design with reverse fixing mechanism
• Gold-plated phosphor bronze male contacts for reliable conductivity
• High-temperature polyamide housing with UL 94 V-0 rating
• Compatible with automated pick-and-place assembly processes

Applications

• Industrial control systems requiring high-density interconnects
• Automotive electronics operating in extreme temperatures
• Power distribution boards needing secure vertical mounting
• Telecommunications infrastructure equipment

Procurement Notes

Verify component authenticity via official Harwin channels or authorized distributors. Confirm RoHS compliance status and specific datasheet revisions before integration. Check for obsolescence notices as availability may vary. Ensure storage conditions maintain integrity of gold plating and polymer housing prior to soldering.

Selection Notes

Select this part for applications demanding vertical board-to-board connectivity with robust mechanical retention. The 1.25 mm pitch allows dense packing while maintaining 2 A per contact capacity. Consider the reverse fixing feature for enhanced stability in vibration-prone environments compared to standard headers.

Part Context

Part of the Harwin Gecko-SL family, known for compact form factors and high reliability. The G125 series specifically targets space-constrained designs requiring durable connections. This model represents a specialized variant within the broader power connector portfolio, focusing on vertical orientation and automated assembly compatibility.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific reverse-fixing configuration. Cross-reference with other G125-MV variants only if mechanical mounting differences are acceptable. Consult Harwin engineering for equivalent performance alternatives.
