G125-MH11005L3R

Overview

The Harwin G125-MH11005L3R is a Gecko-Latch series header and wire housing component featuring a 1.25 mm pitch and 10 positions across two rows. Designed for right-angle through-hole mounting, it utilizes solder pin termination with gold-plated phosphor bronze contacts rated for 2 A current. The shrouded green polyamide (PA) housing ensures UL 94 V-0 flammability compliance. It operates within a temperature range of -65 °C to +150 °C and incorporates jackscrew locking mechanisms for secure board attachment.

Feature Summary

• Jackscrew locking mechanism provides secure board mount retention
• Shrouded design protects contact alignment during mating
• Gold-plated phosphor bronze contacts ensure reliable conductivity
• High-temperature polyamide housing supports extreme environmental conditions

Applications

• Demanding industrial electronic designs requiring high reliability
• Applications subject to extreme vibration environments
• Space-constrained systems needing miniature package performance

Procurement Notes

Verify the specific suffix L3R against official datasheets to confirm surface-mount or specialized variant requirements, as standard Gecko-SL parts typically use different suffixes. Confirm RoHS compliance status directly with the manufacturer documentation before integration. Ensure mating connectors match the 1.25 mm pitch and jack-screw interface specifications precisely.

Selection Notes

Select this component when high-reliability connections in extreme temperatures are required. The 1.25 mm pitch offers significant space savings compared to larger connectors. Verify that the right-angle orientation fits the mechanical layout constraints. Ensure the PCB footprint accommodates the through-hole solder pins and the specific tail length defined in the official specification sheet.

Part Context

This part belongs to the Harwin Gecko family, designed for high-performance applications in miniature packages. The series utilizes patented four-finger copper alloy contacts to withstand extreme conditions. The Gecko-Latch variant specifically integrates screw-fixing features for enhanced mechanical stability in demanding sectors such as aerospace and automotive electronics.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-model compatibility requires verification of pitch, locking mechanism type, and electrical ratings against the original design specifications.
