G125-MH21605L7P

Overview

The G125-MH21605L7P is a male header connector from the Harwin Gecko-Latch series, designed for power-to-board applications. It features a 1.25 mm pitch and a 2x8 position configuration (16 positions total). The component utilizes phosphor bronze contacts with gold plating and a polyamide (PA4T) thermoplastic housing rated UL94 V-0. It employs a surface-mount termination style with horizontal PCB tails. Electrical ratings include a current capacity of 2.8 A and a voltage rating of 250 V. The operating temperature range spans from -65°C to +150°C, with an insulation resistance of 1 GOhm.

Feature Summary

• Horizontal surface-mount design with integrated pick-and-place compatibility for automated assembly.
• Gecko-Latch mechanical system providing secure mating retention between male headers and female receptacles.
• High-temperature polyamide (PA4T) insulation material ensuring stability within extreme thermal environments.

Applications

• Automotive electronic control units requiring high-density power distribution.
• Industrial equipment utilizing compact board-to-board interconnects.
• Telecommunications infrastructure demanding reliable signal and power transmission.

Procurement Notes

Verify the specific suffix 'L7P' against the manufacturer's official datasheet to confirm the tape-and-reel packaging format and horizontal tail orientation. Ensure that the selected variant matches the required surface-mount footprint and pin count specifications for the target printed circuit board layout prior to ordering.

Selection Notes

Select this component when a low-profile, horizontally oriented male header is required for space-constrained designs. The 1.25 mm pitch allows for high density, while the Gecko-Latch mechanism ensures robust connection integrity. Confirm that the 2.8 A current rating and 250 V voltage limit align with the system's electrical requirements and thermal management capabilities.

Part Context

This part belongs to the Harwin Gecko-Latch family, which offers modular connectivity solutions for harsh environments. The G125 series specifically addresses the need for compact, high-reliability interconnects in automotive and industrial sectors. The MH variant denotes a male header with horizontal tails, distinguishing it from vertical or right-angle configurations within the same product line.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 1.25 mm pitch, 16-position count, horizontal SMT tail geometry, and Gecko-Latch mechanical interface specifications.
