What this line on the BOM actually buys
The 6SL5166-0AF01-0AA0 is a spare-part fan subassembly sized for the 150 mm booksize Smart Line module in the SINAMICS S220 drive family, rated for the 36/55 kW module tier — it is the field-replaceable cooling assembly, not a standalone drive or power module. Lifecycle is listed as current on the manufacturer record, which means the part is still being produced and is ordered as a Service / spare component rather than catalog stock; the product class is documented as made-to-order and non-returnable, so the procurement posture is a confirm-at-quote BOM line.
Mounting and module fit
Because the part is a fan subassembly for a booksize-format Smart Line module, the swap happens at the cabinet with the line module de-energized — the fan deck seats into the 150 mm chassis footprint of the matching S220 Smart Line module in the 36/55 kW class, and a fan from a different frame size or a different SINAMICS family will not drop in.
Compliance and shipment controls
RoHS compliance is documented since 08-11-22, and a REACH Article 33 disclosure is on file for lead (CAS-No. 7439-92-1) above the 0.1% w/w threshold — both are the standard EU substance-restriction statements expected on a drive-family spare, not performance certifications. Export classification is AL:N with ECCN:EAR99H, which keeps the part outside U.S. dual-use licensing for most destinations but still requires the standard commercial-invoice and end-use paperwork for cross-border shipment.
Catalog metadata on the listing
The listing carries Group Code R220 and Product Group X0HX under the Siemens Ordering Data Overview family — these are internal catalog codes used to route the line inside the vendor's material master, not functional ratings. Packaging and quantity unit are both 1 Piece, consistent with a single spare-part SKU rather than a service kit.
