Overview
The Harwin G125-FS13405F2R is a Gecko-SL series power-to-board connector socket. It features a 1.25 mm pitch with 34 positions arranged in a dual-row configuration. The component utilizes surface-mount technology (SMT) with reverse fix design for secure board attachment. Contact material is beryllium copper with gold plating, rated for 2 A current and 250 V voltage. Operating temperature range spans from -65 °C to +150 °C. Housing is green nylon. Lifecycle status is obsolete.
Feature Summary
- Reverse fix SMT mounting mechanism ensures stable board connection
- Dual-row 1.25 mm pitch geometry for compact power distribution
- Gold-plated beryllium copper contacts for reliable conductivity
Applications
- Power delivery in dense electronic assemblies
- Industrial control board interconnects
- Telecommunications equipment power interfaces
Procurement Notes
Verify component obsolescence status before integration into new designs. Confirm availability of last-time buy quantities through authorized distributors. Assess supply chain continuity risks associated with discontinued part numbers. Ensure storage conditions comply with manufacturer specifications for aged inventory. Validate compatibility with existing PCB footprints and assembly processes.
Selection Notes
Consider alternative Gecko-SL variants with active lifecycle status for long-term projects. Evaluate mechanical fit within constrained board spaces due to reverse fix profile. Compare thermal performance characteristics against system operating requirements. Review contact plating thickness for intended mating cycle durability. Assess packaging format suitability for automated pick-and-place manufacturing lines.
Part Context
Part belongs to Harwin's Gecko-SL family of high-density connectors. Series emphasizes miniaturization and robust power handling capabilities. Design targets applications requiring reliable electrical connections in space-constrained environments. Family shares common mating interface standards across male and female configurations.
Replacement Considerations
G125-FS13405F3P offers similar specifications with updated lifecycle status. Verify pinout compatibility and mechanical dimensions before substitution. Cross-reference datasheet parameters to ensure functional equivalence. Consult manufacturer for official replacement recommendations.
