The Siemens 6SL3351-3AF31-8DB0 is a Replacement IPD card for the SINAMICS G150 drive series, not a standalone drive module. It carries Product class C, meaning it is manufactured or produced to order and cannot be reused, re-utilized, or returned against credit — so this is a line-item spare you commit to once, not a stockable swap part.
Compliance — what documentation comes with it
The part carries a REACH Article 33 duty-to-inform declaration: Lead (CAS-No. 7439-92-1) is present at >0.1% w/w, so downstream notification is required if this spare goes into a product placed on the EU market.
