G125-MV12005L0R

Overview

The Harwin G125-MV12005L0R is a Gecko-Latch series power-to-board header connector designed for vertical surface-mount applications. It features a 1.25 mm pitch with 20 positions arranged in two rows. The component utilizes male pin contacts made of phosphor bronze with gold plating, housed in polyamide (PA) insulation rated UL 94 V-0. Rated for 2 A current and up to 450 V voltage, it operates within a temperature range of -65°C to +150°C.

Feature Summary

• Vertical SMD mounting configuration for compact board integration
• Gecko-Latch mechanical locking system ensures secure mating retention
• Gold-plated phosphor bronze contacts provide reliable conductivity
• Polyamide housing offers high thermal stability and flame resistance

Applications

• Power distribution modules requiring secure vertical interconnects
• Industrial control systems utilizing surface-mounted power headers
• Automotive electronics needing high-reliability latch mechanisms
• Consumer appliances with restricted vertical space constraints

Procurement Notes

Verify the specific suffix 'L0R' against the manufacturer datasheet to confirm reel packaging and contact orientation. Ensure compatibility with the corresponding female socket counterpart within the same Gecko-Latch family. Confirm RoHS compliance status through official documentation prior to assembly integration.

Selection Notes

Select this part for applications demanding robust mechanical retention via the Gecko-Latch feature rather than standard friction fit. The vertical SMT profile suits boards where horizontal clearance is limited. Verify that the 2-row, 1.25mm pitch aligns with the mating connector footprint and that the 2A rating meets the circuit load requirements.

Part Context

This component belongs to the Harwin Gecko-Latch family, which emphasizes secure connection reliability through integrated latching mechanisms. The G125 series specifically targets power-to-board connections, offering various configurations including shrouded and unshrouded options in both vertical and right-angle orientations across different pitch sizes.

Replacement Considerations

Direct substitutes include other Harwin G125 series variants with matching 1.25mm pitch and 20-position layout. Cross-reference the specific suffix codes to ensure identical mounting style and contact gender. Generic 1.25mm headers lack the Gecko-Latch retention feature and are not functionally equivalent.
