G125-MS12005L3P

Overview

The Harwin G125-MS12005L3P is a Gecko-Latch series power-to-board connector featuring a 1.25 mm pitch and 20 positions arranged in two rows. It utilizes male pin contacts made of phosphor bronze with gold plating, housed in green polyamide (PA) insulation rated UL94 V-0. Designed for surface mount technology (SMT), it supports board-to-board and wire-to-board systems with a straight mounting angle. The component operates within a temperature range of -65°C to +150°C, offering a current rating of 2A per contact and voltage ratings of 250V or 450V.

Feature Summary

• Integrated SMT latching mechanism ensures secure mechanical retention during assembly and operation.
• Gold-plated phosphor bronze contacts provide reliable electrical conductivity and corrosion resistance.
• Polyamide housing offers high thermal stability and flammability compliance for robust performance.

Applications

• High-density power distribution in compact electronic modules
• Board-to-board interconnections requiring secure surface-mount retention
• Wire-to-board connections in industrial control systems

Procurement Notes

Verify the specific datasheet version to confirm voltage ratings, as sources indicate variations between 250V/450V and 600V. Ensure compatibility with pick-and-place equipment due to the integrated latch design. Confirm RoHS compliance status through official manufacturer documentation before integration into regulated products.

Selection Notes

Select this part when a secure, low-profile SMT connection is required for power applications. The Gecko-Latch feature distinguishes it from standard headers by providing mechanical locking without additional fasteners. Consider the 1.25mm pitch constraints and verify that the 2A current rating meets the circuit requirements.

Part Context

This component belongs to the Harwin Gecko family, designed for space-constrained environments. It serves as a male header variant within the G125 series, specifically engineered for surface-mount processes. The model number indicates a 2x10 configuration with specific latch and packaging attributes defined by the manufacturer's coding system.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 1.25mm pitch, 2-row SMT form factor, and latching mechanism specifications with other manufacturers' offerings.
