The Siemens 6SL3351-3AE38-4DB0 is a replacement IPD card for the SINAMICS G150 drive family. This is a spare part, not a full drive module — it goes into the control section of an existing G150 chassis when the original IPD board fails or needs swapping during a retrofit. Product class C means it's manufactured or produced to order, not a stocked shelf item. That's another SKU I don't need to keep on the shelf until a G150 goes down — order it when the fault code points to the IPD card.
REACH compliance note: the part contains lead above the 0.1% threshold (CAS-No. 7439-92-1). That's typical for electronic assemblies with soldered components; the Article 33 duty-to-inform applies if you're further distributing or recycling.
Group code R2SC and product group 4Q30 are Siemens internal classification tags — they help with ordering data overview and cross-referencing in the Siemens Industry Mall. The product family is listed as Ordering Data Overview, which is the standard umbrella for spare parts documentation.
