It is listed as a spare part, meaning it is the exact replacement for an existing NX15 in a live machine cabinet, not a new-design option.

Frequently asked questions
Where can I buy 6SL3040-0NB00-0AA0 and how do I get a price?
This part is sourced and quoted to order against an RFQ through independent industrial automation distribution. Current pricing and availability are confirmed at quote time — submit an RFQ for a firm price and lead time.
Will 6SL3040-0NB00-0AA0 drop into a panel specified around a different Siemens control board?
No. The NX15 is a SINAMICS drive control extension for the SINUMERIK 840D sl ecosystem. It is not a functional second-source for a Siemens S7-300 CPU or a LOGO! expansion module — those are different product families with different backplane interfaces and firmware requirements.

Specific declarations (RoHS, REACH, CE, UL) are available from the manufacturer's documentation portal; the part number 6SL3040-0NB00-0AA0 is the reference for pulling the correct certificate.
