G125-FS11205F1P

Overview

The G125-FS11205F1P is a 12-position surface mount receptacle connector from the Harwin Gecko Screw-Lok series. It features a 0.049-inch (1.25mm) pitch and utilizes gold-plated contacts for reliable signal transmission. Designed for board-to-board or cable applications, this component supports a rated current of 2A and operates within a temperature range of -65°C to +150°C. The housing is constructed from green polyamide with UL94 V-0 flammability rating.

Feature Summary

• Integrates a mechanical locking system for secure retention during vibration
• Supports pick-and-place automated assembly processes
• Features polarized keying to prevent misalignment during mating

Applications

• Automotive electronic systems
• General industrial equipment
• High-reliability signal interconnects

Procurement Notes

Verify the specific suffix F1P against official datasheets to confirm the screw-lock variant. Ensure compatibility with mating pins regarding pitch and row configuration. Cross-reference material composition data for regulatory compliance requirements prior to final procurement decisions.

Selection Notes

Select this model when high-vibration resistance is required due to its integrated locking mechanism. The SMT footprint suits automated manufacturing lines. Confirm that the 1.25mm pitch aligns with the target PCB layout constraints and mating interface specifications.

Part Context

This component belongs to the Gecko-SL family, which emphasizes high-reliability performance in demanding environments. The series combines standard signal connectivity with robust mechanical retention features, distinguishing it from non-locking variants within the broader G125 product line.

Replacement Considerations

Direct substitutes include other Gecko-SL receptacles with identical pin counts and locking mechanisms. Verify that alternative part numbers maintain the same 1.25mm pitch and surface mount termination style to ensure physical and electrical compatibility.
