G125-MS11605L1P

Overview

The Harwin G125-MS11605L1P is a Gecko SL series male header connector designed for surface mount technology. It features a 1.25 mm pitch and a double-row configuration with 16 positions (8+8). The contacts are made of phosphor bronze with gold plating, rated for 2 A current and up to 450 V voltage. The housing is constructed from green polyamide (PA4T) with UL94 V-0 flammability rating. Key specifications include an insulation height of 4.90 mm, a mating stack height of 7.33 mm or 7.4 mm, and an operating temperature range of -65°C to +150°C.

Feature Summary

• Integrated latching mechanism with through-board barbs ensures secure mechanical connection for 1.6mm PCB thickness.
• Surface mount design facilitates automated pick-and-place assembly processes.
• Polarized keying prevents incorrect mating orientation during board-to-board connections.

Applications

• Board-to-board interconnections in compact electronic assemblies
• Power distribution within dense circuit boards
• Signal transmission in high-density I/O interfaces

Procurement Notes

Verify the specific suffix 'L1P' corresponds to the tape and reel packaging format required for your production line. Confirm that the 1.6mm PCB thickness compatibility aligns with your board design specifications. Ensure the gold contact plating thickness meets your corrosion resistance requirements. Cross-reference the RoHS compliance status with your environmental regulations. Validate the lead time availability directly with authorized distributors as stock levels fluctuate.

Selection Notes

Select this component when a low-profile, vertically oriented SMT header is required for reliable board stacking. The 1.25 mm pitch offers a balance between density and manufacturability. The integrated latch feature reduces the need for additional securing hardware. Consider the 450 V rating if higher voltage isolation is necessary compared to standard 250 V options. Ensure the PA4T material properties suit the thermal environment of the application.

Part Context

This part belongs to the Harwin Gecko SL family, which specializes in high-reliability connectors for space-constrained applications. The Gecko series is known for its robust latching system and precise alignment features. The G125 designation indicates the 1.25 mm pitch variant. This specific model represents a male pin header intended for mating with corresponding female sockets or cable assemblies.

Replacement Considerations

Direct substitutes may include other Harwin Gecko models with similar pitch and row count, such as G125-MS11605M1R, though packaging and latch variations must be verified. Generic replacements require matching the 1.25 mm pitch, 16-position double-row layout, and SMT mounting style. Always validate mechanical dimensions and electrical ratings before substituting.
