EOL/HOT sourcing — what this means for your BOM
The 1FK7061-7AF71-1SA0: For a line-down scenario or a long-running OEM program, this status means the procurement window is finite: independent surplus and broker inventory is the remaining path, and lot-specific availability must be confirmed at RFQ before committing to a quantity.
Where the 1FK7 series fits
The Siemens 1FK7 family — positioned in the SIMOTICS S line — are high-dynamic synchronous servo motors used in precision positioning axes: packaging machinery, printing, wood-working, and general automation. The order-code suffix 1SA0 indicates a specific winding, feedback, and shaft configuration; replacing it requires matching the mechanical interface and encoder type to the existing drive.
