Spare-part identity and what ships
Siemens 6SL5166-3AH00-0AA0 is the factory-labelled spare-part DC link cover for the SINAMICS S220 drive family, sized for the 200 mm line/motor module footprint — meaning it slides onto the DC bus section of the affected module as a direct replacement, not a kit. The product is classed as Group Code R220 under Product Group X0HX, in the Ordering Data Overview family — a categorisation that places it inside the Siemens spare-parts ordering flow rather than the new-build converter list.
Lifecycle class and order handling
Lifecycle stage is current and the order code is live on the Siemens spare-parts list, so sourcing through the standard replacement-parts channel is open. The product class is C — produced to order, non-returnable and non-reusable for credit — which matters operationally: a kit pulled and not consumed cannot be restocked on credit, so order the quantity that maps to the actual repair scope.
Compliance posture for stock records
Export classification is AL: N with ECCN: EAR99H, so cross-border shipments do not require a licence for the standard industrial destinations — useful when a spare has to be air-freighted to a line-down site.
Carton and how it arrives
Quantity unit is 1 Piece with a packaging quantity of 1, so each cover ships as its own line item — straightforward for kitting against a single repair ticket without leftover surplus on the shelf.
