G125-FS11205F1R

Overview

The Harwin G125-FS11205F1R is a 12-position female receptacle connector from the Gecko series, designed for surface mount applications. It features a 1.25mm pitch and dual-row configuration with gold-plated contacts. The unit utilizes a latching mechanism for secure board-to-board or cable-to-board connections. Rated for 2A current and operating within a -65°C to +150°C temperature range, it employs polyamide insulation and UL94 V-0 rated materials.

Feature Summary

• Dual-row surface mount receptacle design for compact stacking
• Integrated latching system ensures secure mechanical retention
• Gold-plated circular contacts provide reliable signal transmission
• High-temperature resistant polyamide insulation material

Applications

• Automotive electronic systems
• General purpose industrial equipment
• Board-to-board interconnects
• Cable-to-board assemblies

Procurement Notes

Verify the specific ordering suffix 'F1' against official Harwin documentation to confirm the exact contact plating thickness and material composition. Ensure compatibility with mating pin headers from the same Gecko series. Confirm that the surface mount footprint matches the target PCB design guidelines provided in the manufacturer's datasheet before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, high-reliability interconnect solution is required for space-constrained designs. The dual-row format supports higher density connections compared to single-row alternatives. Consider the latching feature if vibration resistance is critical. Verify that the 1.25mm pitch aligns with the overall system layout requirements and mating connector specifications.

Part Context

This part belongs to the Harwin Gecko Latch family, which offers robust connectivity solutions for demanding environments. The G125 series specifically targets applications requiring high reliability and durability. As a receptacle, it mates with corresponding pin headers to establish electrical pathways in complex electronic assemblies.

Replacement Considerations

Direct substitutes include other Harwin Gecko series receptacles with identical pin counts and pitch, such as G125-FS11205L0R, provided the specific suffix variations match the required plating and packaging specifications.
