G125-MV11005L0R

Overview

The Harwin G125-MV11005L0R is a Gecko-Latch series power-to-board connector designed for vertical surface-mount technology (SMT) applications. It features a 1.25 mm pitch with a 2x5 position configuration, totaling ten contacts. The component utilizes male pin sockets with gold-plated phosphor bronze contacts housed in polyamide insulation. Rated for 2 A current and 250 V voltage, it operates within a temperature range of -65°C to +150°C. The unit weighs 285 mg and is supplied in tape-and-reel packaging for automated assembly.

Feature Summary

• Vertical SMT mounting style enables direct board integration without through-hole drilling.
• Gecko-Latch mechanism provides secure mating retention between header and socket pairs.
• Gold-plated phosphor bronze contacts ensure reliable conductivity and corrosion resistance.
• Polyamide housing offers high thermal stability and UL 94 V-0 flammability rating.

Applications

• Automotive electronic control units requiring robust power distribution
• Industrial automation systems utilizing high-density power connections
• Telecommunications infrastructure equipment needing reliable signal integrity
• Medical device internal power routing with strict space constraints

Procurement Notes

Verify the specific suffix 'L0R' against official Harwin documentation to confirm the exact reel quantity and tape specifications. Ensure compatibility with standard pick-and-place machinery settings for vertical headers. Cross-reference RoHS and REACH compliance status directly with the manufacturer's latest declaration before procurement. Confirm that the intended mating socket belongs to the same Gecko-Latch family to guarantee mechanical locking functionality.

Selection Notes

Select this component when vertical surface-mount installation is required for power-to-board interfaces. The 1.25 mm pitch allows for compact circuit board layouts while maintaining adequate spacing for high-current applications. Consider the 3.0 mm contact length for appropriate board thickness and solder joint formation. Evaluate the operating temperature range against the environmental conditions of the final application to ensure long-term reliability under thermal stress.

Part Context

This part belongs to the Harwin Gecko-Latch family, which specializes in high-reliability interconnect solutions. The series is characterized by its unique latching mechanism that prevents accidental disconnection during vibration or shock. The G125 designation indicates the 1.25 mm pitch variant within the broader Gecko product line, catering to modern electronics demanding higher density and improved performance.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires identical pitch, contact count, and latching mechanism compatibility. Verify mechanical dimensions and electrical ratings against the original design specifications before considering alternative manufacturers.

FAQ

What is the mating retention force of the Gecko-Latch mechanism?

The datasheet does not specify the exact numerical value for mating retention force; consult the official Harwin technical specification for precise mechanical data.

Is this connector compatible with non-Harwin mating sockets?

Compatibility is not guaranteed with third-party components due to the proprietary Gecko-Latch design. Use only verified Harwin mating connectors to ensure proper latching function.

What is the maximum reflow soldering temperature allowed?

Specific reflow profile limits are not detailed in the provided text. Refer to the manufacturer's assembly guidelines for precise thermal processing parameters.
