What 6SL5166-0AH00-0AA0 actually is
The 6SL5166-0AH00-0AA0 is the 200 mm booksize replacement fan for the SINAMICS S220 drive platform — a Siemens spare, ordered one piece at a time, classed as a non-returnable line item because it is produced against the order rather than held as re-usable stock.
Production status and what that means for a service spare
The product class carries a hard caveat: items manufactured to order are not returnable for credit, so the RFQ quantity should match the actual installed base (one fan per affected chassis, plus the usual service-floor hold) rather than a speculative overstock position.
Compliance and shipping posture
Export classification is AL:N / ECCN:EAR99H, which means no export licence is required for typical destinations and the part can move freely on a standard commercial invoice.
