What the duty envelope means on the line
The 1FL2103-2AF10-0MC0 ships as a SIMOTICS S-1FL2 low-inertia servo in the 30 mm shaft-height frame, rated 0.2 kW at a 400 V 3AC supply with a rated speed of 3000 rpm and a stall/rated torque of 0.64 Nm — the matched drive family is the SINAMICS S200, so sizing the motor outside that drive's bus and control loop will cost you the optimized dynamic response the pair is built around. Holding brake is included, the resolver-equivalent feedback is the AM21-bit absolute encoder on the hybrid connector tail, and the shaft is plain with tolerance N — there is no oil seal, so the IP54 rating applies to the body and cable entry but not to a pressurized oil environment.
Lifecycle, compliance, and what crosses with it
Siemens lists the 1FL2103-2AF10-0MC0 as an active product (lifecycle stage current), so this is not a last-time-buy item — quote against the BOM at the panel-build stage rather than scrounging surplus, and stock the spare once for the commissioning floater instead of as a long-tail consumable. Siemens cataloging codes for this line: Group Code R220, Product Group X0DJ, Product Class C (made-to-order, non-returnable for credit) — that class flag means cancellations and returns are not the safety net you'd get on a stocked shelf item, so commit the order quantity to the build sheet before cutting the PO.
Packaging, footprint, and panel-side handling
Single-piece carton, packaging footprint 315.00 x 182.00 x 172.00 mm — small enough to ride a standard parts shelf but tall enough that the hybrid connector pigtail wants to be supported when you unbox it, not dragged across the bench.
