G125-FS12005F3R

Overview

The Harwin G125-FS12005F3R is a Gecko-SL series power-to-board connector featuring a 1.25 mm pitch and 20 positions in a dual-row configuration. It utilizes female socket contacts with gold plating on phosphor bronze substrates, rated for 2 A current. Designed for surface mount installation at a right angle, the component employs solder termination and includes jackscrew locking mechanisms. The housing is constructed from green polyamide (PA) material, ensuring UL 94 V-0 flammability rating and operation within a -65°C to +150°C temperature range.

Feature Summary

• High-density interconnect capability enabled by a compact 1.25 mm pin spacing
• Secure mechanical coupling achieved through integrated jackscrew locking systems
• Robust electrical performance supported by four-finger patented copper alloy contact design

Applications

• Space-constrained electronic assemblies requiring high reliability
• Industrial control systems operating under extreme vibration conditions
• Automotive electronics demanding wide thermal stability

Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration against official datasheets. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure compatibility with automated pick-and-place equipment specifications for surface mount assembly processes.

Selection Notes

Select this component when board space optimization is critical due to its miniature profile compared to standard connectors. Validate that the 2 A per contact current rating meets circuit requirements. Ensure the right-angle orientation aligns with mechanical constraints and that the jackscrew feature suits the enclosure design for secure mating.

Part Context

This part belongs to the Harwin Gecko-SL family, engineered for demanding applications where size and performance are paramount. The series offers significant space savings over larger pitch connectors while maintaining high reliability in harsh environments. It supports various configurations including headers, cable assemblies, and power-to-board solutions.

Replacement Considerations

No direct public substitute part numbers are documented for this specific configuration. Evaluate other Gecko-SL variants with matching pitch and position counts if availability is an issue.
