G125-MV25005L0R

Overview

The Harwin G125-MV25005L0R is a Gecko-Latch series power-to-board connector designed for vertical surface-mount technology (SMT) applications. It features a male header configuration with a 1.25 mm pitch and a dual-row arrangement providing 50 positions. The component utilizes phosphor bronze contacts with gold plating to ensure reliable conductivity within a polyamide housing rated UL 94 V-0. Engineered for high-density power distribution, it supports a current rating of 2 A per contact and withstands voltages up to 250 V AC or 450 V DC. The unit operates reliably across an extended temperature range from -65°C to +150°C.

Feature Summary

• Vertical SMT mounting design facilitates automated pick-and-place assembly processes
• Dual-row shrouded structure provides robust mechanical stability and pin alignment
• Gold-plated phosphor bronze contacts ensure low resistance and corrosion resistance
• UL 94 V-0 rated polyamide insulation supports high-temperature soldering profiles

Applications

• High-density power distribution in industrial control systems
• Power supply interconnections in telecommunications infrastructure
• Board-to-board connections in automotive electronic modules
• Compact power interfaces in medical diagnostic equipment

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging suitable for automated manufacturing lines. Confirm that the voltage rating aligns with system requirements, as specifications may vary between AC and DC ratings. Ensure compatibility with mating female connectors within the same Gecko-Latch family. Check RoHS compliance status for environmental regulations. Validate thermal performance against peak operating temperatures during soldering and service.

Selection Notes

Select this model when vertical orientation and surface-mount efficiency are required for space-constrained designs. The 1.25 mm pitch allows for higher pin counts compared to larger spacing alternatives. Consider the 2 A current capacity for moderate power loads. Verify that the 50-position count matches circuit requirements without excessive unused pins. Evaluate the operating temperature range against environmental conditions.

Part Context

This component belongs to the Harwin Gecko-Latch product line, which specializes in micro-miniature connectors for demanding environments. The G125 prefix denotes the 1.25 mm pitch series. The MV designation identifies it as a male vertical header. This series is engineered for reliability in harsh conditions, offering superior vibration resistance and secure latching mechanisms compared to standard board mount headers.

Replacement Considerations

Direct substitutes must maintain the 1.25 mm pitch, 50-position count, and vertical SMT form factor. Compatible alternatives include other Gecko-Latch variants with matching electrical ratings. Cross-reference mating female connectors to ensure interface compatibility. Verify that replacement parts meet the same UL 94 V-0 flammability and temperature standards.
