G125-FS15005F1P

Overview

The Harwin G125-FS15005F1P is a Gecko-SL series power-to-board connector designed for surface-mount technology. It features a 1.25 mm (0.049 in) pitch with a 2x25 position layout, totaling 50 contacts. The component utilizes female socket contacts made of beryllium copper with gold plating. Rated for 2 A current and operating within a temperature range of -65°C to +150°C, it employs a green nylon housing. The connector is straight-mounted and terminated via solder, packaged in tape-and-reel format.

Feature Summary

• Surface-mount design optimized for automated PCB assembly processes
• Threaded locking mechanism ensures secure mating retention
• Gold-plated beryllium copper contacts provide reliable signal integrity
• High-temperature polyamide housing supports demanding thermal environments

Applications

• Industrial control systems requiring robust board-level interconnects
• Automotive electronics modules subject to high thermal stress
• Medical equipment needing reliable high-density connections
• Telecommunications infrastructure hardware

Procurement Notes

Verify the specific ordering suffix against the official Harwin datasheet to confirm exact contact configuration, housing color, and packaging type. Ensure compatibility with standard SMT reflow profiles and check for RoHS/REACH compliance documentation prior to integration into production lines.

Selection Notes

Select this component when a high-density, vertically mounted female header is required for surface-mount applications. Consider the 1.25 mm pitch constraints and 2 A current rating per contact. Evaluate the need for threaded locking features and high-temperature resistance (-65°C to +150°C) relative to the target environment.

Part Context

This part belongs to the Harwin Gecko-SL family, characterized by its compact form factor and high reliability. The series is engineered for space-constrained applications where secure mechanical locking and stable electrical performance are critical. It complements matching male headers and cable assemblies within the same ecosystem.

Replacement Considerations

Direct substitutes include G125-FS15005F1R, which shares identical electrical and mechanical specifications but differs in packaging format. Verify pinout orientation and mounting dimensions before swapping components to ensure PCB footprint compatibility.
