G125-FS11205F3P

Overview

The G125-FS11205F3P is a 12-position female receptacle connector from Harwin's Gecko Screw-Lok series. It features a dual-row surface mount design with a 1.25mm (0.049 inch) mating pitch and 1.25mm row spacing. The connector utilizes gold-plated contacts rated for 2A current and 450V voltage, housed in green PA4T insulation. Key mechanical attributes include jackscrews for secure board retention, pick-and-place compatibility, and polarizing keys. It operates within a temperature range of -65°C to 150°C.

Feature Summary

• Dual-row surface mount receptacle configuration
• Integrated jackscrew locking mechanism
• Polarizing key for orientation assurance
• Pick-and-place compatible construction

Applications

• Automotive electronics interconnects
• General purpose signal connections
• Stacking applications requiring low profile
• Cable mating solutions

Procurement Notes

Verify the specific suffix F3P against project requirements to ensure correct reverse fix board mount orientation and stacking height specifications. Confirm that the jack screw style matches the assembly tooling available. Cross-reference the material composition data sheet for halogen-free compliance if required by environmental standards. Ensure the selected packaging format aligns with automated placement equipment capabilities.

Selection Notes

Select this component when a robust, low-profile dual-row SMT solution is needed with positive mechanical locking. The 1.25mm pitch offers a balance between density and handling ease. Consider the 2A rating for signal integrity needs. The polarizing key prevents incorrect mating. Evaluate the reverse fix mounting style against PCB layout constraints and available board space for the protruding jackscrews.

Part Context

This part belongs to the Gecko Screw-Lok (G125) family, designed for high-reliability applications. The series provides a low-profile interconnect solution suitable for both stacking and cable mating. The G125 line emphasizes durability and secure connection through its unique jackscrew system, distinguishing it from standard snap-fit connectors in the same pitch class.

Replacement Considerations

Direct substitutes must match the 1.25mm pitch, 12-pin count, dual-row SMT form factor, and jackscrew locking mechanism. Verify identical electrical ratings and insulation material properties. Generic 1.25mm connectors without jackscrews are not functionally equivalent due to the lack of secure retention.
