G125-MH20605L3P

Overview

The Harwin G125-MH20605L3P is a male plug connector from the Gecko Latch series, designed for through-board (THT) termination. It features a double-row configuration with six contacts arranged in a 2x3 pin layout. The component utilizes a 1.25 mm pitch and includes latches that engage with throughboard barbs to secure connections on PCBs up to 4.7mm thick. Rated for 450VAC/DC and 2A current, it employs phosphor bronze contacts with gold plating and UL94 V-0 green nylon insulation.

Feature Summary

• Double-row male plug design with integrated latching mechanism for secure board attachment
• Through-board termination compatible with PCB thicknesses up to 4.7mm via barbed latches
• High-reliability construction using UL94 V-0 rated green nylon insulation and gold-plated phosphor bronze contacts

Applications

• Board-to-board interconnections requiring high reliability
• Wire-to-board connections in industrial control systems
• Electronics assemblies demanding secure mechanical retention in vibration-prone environments

Procurement Notes

Verify the specific suffix code against official Harwin documentation to confirm contact count and row configuration, as variations exist within the G125 series. Ensure compatibility with mating sockets and verify that the target PCB thickness falls within the 4.7mm limit supported by the throughboard barb latch system. Cross-reference the voltage and current ratings with application requirements before finalizing procurement.

Selection Notes

Select this component when a double-row male connector with positive latching action is required for through-hole mounting. The 1.25 mm pitch allows for dense circuit layouts while maintaining robust electrical performance. Consider the 450VAC/DC rating and 2A current capacity to ensure suitability for the intended signal or power transmission needs within the specified temperature range.

Part Context

This part belongs to the Harwin Gecko G125 series, which specializes in high-reliability connectors with a 1.25 mm pitch. The series is engineered for demanding applications where secure connection integrity is critical. The G125-MH20605L3P specifically represents a male plug variant designed for through-board installation, distinguishing itself from surface mount alternatives within the same family.

Replacement Considerations

Direct substitutes must match the 1.25 mm pitch, double-row 2x3 configuration, and through-board latching mechanism. Verify that alternative components support the same 4.7mm PCB thickness capability and maintain equivalent UL94 V-0 flammability ratings. Ensure mating interface compatibility with existing socket housings to prevent assembly issues.
