Overview
The Harwin G125-FV12005F2P is a Gecko-SL series power-to-board connector designed for vertical through-hole mounting. It features a 1.25 mm (0.049 in) contact pitch and a 2-row configuration with 20 positions. The component utilizes gold-plated copper alloy contacts rated for 2 A current and 250 V voltage. It operates within a temperature range of -65 °C to +150 °C and employs a jackscrew locking mechanism for secure mating.
Feature Summary
- Vertical power-to-board architecture with screw-locking retention
- Gold-plated high-performance alloy contacts for reliable conductivity
- High-temperature resistant polyamide insulation material
- Through-hole solder pin termination for board integration
Applications
- Industrial control system interconnects
- Power distribution modules
- Telecommunications equipment backplanes
- Automotive electronic assemblies
Procurement Notes
Verify the specific suffix 'F2P' against official datasheets to confirm orientation and packaging details, as variations exist within the Gecko-SL family. Ensure compatibility with mating male headers regarding row spacing and locking mechanism type. Confirm RoHS compliance status via manufacturer documentation prior to procurement.
Selection Notes
Select this model for applications requiring robust vertical power connections with mechanical security. The jackscrew feature provides superior vibration resistance compared to standard press-fit connectors. Verify that the 2 A per contact rating meets circuit requirements and that the 1.25 mm pitch fits the available PCB footprint constraints.
Part Context
This component belongs to the Harwin Gecko-SL micro-miniature connector series, known for high-density interconnect solutions. The series supports various configurations including signal and power variants, catering to demanding environments requiring reliable electrical performance and mechanical durability across diverse industrial sectors.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific variant. Cross-reference with other Harwin Gecko-SL female headers if modifications to pitch or row count are permissible. Ensure any alternative maintains identical locking mechanism and current ratings.
