What this card is and where it fits
The 6SL3054-2FB10-1BA0 is a SINAMICS S150 CompactFlash card loaded with firmware version V5.1.1. It carries the firmware image that boots the drive controller — no card, no start. This isn't a standard shelf-stocked accessory; it's classified as a product made to order, requiring engineering services, and cannot be re-used or utilized (design to customer). That means each card is tied to a specific drive order and firmware config, so swapping between units isn't the intended use. The card itself is a single piece, packaged one per unit. Group code R220 and product group 4923 are the internal Siemens classification tags — useful for cross-referencing against your BOM or Siemens ordering system if you're tracing a replacement.
Lifecycle and sourcing reality
For compliance documentation, the card has been RoHS compliant since 03-05-23 and carries a REACH Article 33 notification for diboron trioxide (CAS 1303-86-2) above 0.1% w/w. No UL or IEC marks are listed in the record.
