G125-MH15005M4R

Overview

The Harwin G125-MH15005M4R is a Gecko-SL series male header connector featuring 10 positions arranged in a dual inline (DIL) configuration. It utilizes a 1.25 mm pitch with a 1.25 mm row spacing and operates at a current rating of 2 A per contact. The component employs phosphor bronze contacts with gold plating and offers a wide operating temperature range from -65°C to +150°C. Designed for right-angle through-hole mounting, it includes screw-lock board mount features and meets UL 94 V-0 flammability standards.

Feature Summary

Incorporates patented four-finger copper alloy contacts for high reliability under extreme vibration
Features internally threaded screw-lock mechanism for secure board mounting
Provides significant space savings compared to larger high-performance connectors

Applications

Demanding electronic product designs requiring high performance in miniature packages
Applications subject to extreme vibration conditions
Systems operating within wide temperature ranges

Procurement Notes

Verify the specific suffix M4R against official datasheets to confirm tape-and-reel packaging status. Ensure compatibility with mating female connectors within the Gecko-SL family. Confirm that the right-angle orientation and screw-lock mounting style align with the target PCB layout requirements before procurement.

Selection Notes

Select this part when a low-profile, high-reliability connection is required for space-constrained designs. The 1.25 mm pitch allows for higher density than Micro-D alternatives. Ensure the application environment stays within the specified -65°C to +150°C operational limits and requires the specific right-angle through-hole termination style.

Part Context

This component belongs to the Harwin Gecko-SL family, designed for high-reliability rectangular signal applications. The series is characterized by its 1.25 mm pitch and robust construction suitable for harsh environments. It represents a specialized solution for engineers needing durable connections in compact form factors.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Cross-reference with other G125-MH headers if pin count or pitch differs, but verify mechanical fit and locking mechanism compatibility carefully.
