Overview
The G125-MV21605L2P is a Gecko-Latch series power-to-board connector manufactured by Harwin. It features a 1.25 mm pitch, double-row configuration with 16 positions (2x5). The component utilizes male pin contacts made of phosphor bronze with gold plating, rated for 2 A current and 450 V voltage. Designed for vertical through-board solder termination, it includes latching mechanisms compatible with 2.4 mm PCBs. Operating temperature ranges from -65°C to +150°C, with UL94 V-0 insulation flammability rating.
Feature Summary
- Vertical through-board mounting with integrated latching barbs for secure PCB attachment
- Gold-plated phosphor bronze contacts ensuring reliable electrical performance
- High-temperature thermoplastic insulation supporting operation up to +150°C
Applications
- Power distribution in industrial control systems
- Server and data center power supply connections
- Automotive electronics power interfaces
Procurement Notes
Verify the specific suffix 'L2P' against official Harwin documentation to confirm latch compatibility and packaging details. Ensure PCB design accommodates the 4.5mm termination height and 2.4mm board thickness requirements specified for this Gecko-Latch variant. Cross-reference RoHS compliance status directly with the manufacturer's latest declaration.
Selection Notes
Select this connector when vertical orientation and mechanical latching are required for high-reliability power applications. The 1.25 mm pitch allows for dense power routing while maintaining 2 A per contact capacity. Consider the 16-position layout for balanced power distribution needs in space-constrained environments requiring robust mechanical retention.
Part Context
This part belongs to the Harwin Gecko-Latch family, designed for high-reliability power-to-board connections. The MV designation indicates a male vertical connector, while the 21605 code specifies the 2-row, 16-position configuration. The L2P suffix typically denotes specific packaging or latch variations within the Gecko product line, distinguishing it from standard non-latching variants.
Replacement Considerations
Compatible substitutes include other Harwin Gecko-Latch vertical connectors with matching 1.25 mm pitch and 16 positions, such as G125-MV21605L0R or G125-MV21605L2R, provided they meet the same voltage, current, and thermal specifications.
