Where the 1FK7042-5AF71-1FB3 sits in the cabinet
Lifecycle status on file is eol_hot, which means the catalog entry has been pulled from the active Siemens configurator but the part is still circulating through surplus and broker channels for service replacement on installed machines.
What the 5.44 kg frame class means on the shop floor
Servo motors in this frame size typically feed packaging indexers, small-format converting lines, and lab/feeders where the high dynamic response of the 1FK7 platform matters more than continuous-torque rating — the compact designation is exactly that trade.
Storeroom posture for a line-down spare
Because the lifecycle read is eol_hot, the practical storeroom move is to treat the 1FK7042-5AF71-1FB3 as a critical spare with a tighter min/max rather than a routine replenisher — independent-channel supply is lot-specific and confirmed at RFQ, not a standing shelf line. Quotations on the -1FB3 run through independent distribution against the BOM line; current pricing and any available unit count come back with the quote rather than off a published list.
