The 6SL3353-3AG41-0AA0 is a Siemens SINAMICS S120 replacement IPD (Interface and Protection) card designed specifically for air-cooled Active Line Modules. This is the board that handles the line-side interface and protection logic inside the drive cabinet — not a standalone module, but the control/diagnostic PCB that plugs into the Active Line Module assembly. It carries Group Code R2SC and Product Group 4Q30, which are Siemens internal classification codes that identify this as a power-drive control board within the S120 platform. These codes are useful for cross-referencing in Siemens ordering tools or when reconciling a BOM against a legacy cabinet drawing.
Siemens lists this part as active. The lifecycle stage is marked mature, meaning it is a well-established, stable design — no imminent end-of-life signal, but not a new-release product either. The product class is C: manufactured/produced to order, not reusable or returnable. This is important for procurement: it is not a stocked shelf item. Each unit is built per order, so lead time is not off-the-shelf. RoHS compliance dates from July 1, 2017.
