G125-FS15005F2P

Overview

The G125-FS15005F2P is a Gecko-SL series power-to-board connector manufactured by Harwin Inc. It features a 1.25 mm (0.049 in) pitch with 50 positions arranged in two rows. The component utilizes female socket contacts made of copper alloy with gold plating, rated for 2 A current and up to 450 V voltage. Designed for surface mount installation, it employs solder pin termination and includes reverse fix technology for secure PCB attachment. The housing is constructed from halogen-free polyamide (PA4T/Nylon 4T), offering a green color and supporting an operating temperature range from -65°C to +150°C.

Feature Summary

• Reverse fix mounting mechanism ensures secure attachment to the printed circuit board during surface mount assembly.
• High-temperature resistant polyamide insulation material supports operation in demanding thermal environments.
• Gold-plated copper alloy contacts provide reliable electrical conductivity and corrosion resistance.
• Halogen-free construction complies with environmental safety standards for electronic components.

Applications

• Power distribution modules requiring high-density connections
• Industrial control systems operating in elevated temperature conditions
• Telecommunications infrastructure equipment
• Automotive electronics applications

Procurement Notes

Verify that the specific part number matches the required reverse fix configuration and surface mount style. Confirm the housing material specification aligns with halogen-free requirements if mandated by project standards. Ensure compatibility with the mating male header within the same Gecko-SL series family. Check for any specific RoHS or REACH compliance documentation relevant to the manufacturing batch.

Selection Notes

Select this component when a high-density 50-position interface is required for power delivery on a PCB. The choice is driven by the need for a robust surface mount solution with a 1.25 mm pitch. Consider the reverse fix feature for enhanced mechanical stability during reflow soldering. Evaluate the thermal rating against the operational environment to ensure the 150°C maximum limit is sufficient.

Part Context

This connector belongs to the Harwin Gecko-SL series, designed specifically for power-to-board applications. The series emphasizes high reliability and compact form factors suitable for modern electronic assemblies. The G125 prefix indicates the 1.25 mm pitch standard, while the FS suffix denotes the specific socket configuration and mounting style within the product line.

Replacement Considerations

Direct substitutes must maintain the 1.25 mm pitch, 50-position count, and reverse fix surface mount characteristics. Verify that any alternative component shares the same voltage and current ratings. Compatibility with existing mating headers is critical; ensure the replacement uses the corresponding male contact type from the same manufacturer's ecosystem.
