I'm making a Nixie Clock and I had to buy from ebay some old SN74141 (KM155ID1 equivalent). Is there some newer IC which does the same things as this one, or similar, that I could get from big suppliers like Mouser, LCSC or DigiKey?

This question appears to be off-topic. The users who voted to close gave this specific reason:
- "Questions seeking recommendations for specific products or places to purchase them are off-topic as they are rarely useful to others and quickly obsolete. Instead, describe your situation and the specific problem you're trying to solve." – Bimpelrekkie, Andy aka, PlasmaHH, Leon Heller, CL.
The 74141's datasheet includes an equivalent circuit diagram for its output stage. You could always just replicate that output stage in discrete components and use a modern decoder IC (e.g. 74HC42) to provide the decoding logic.
K155ID1 seem to be still manufactured in Russia, and there also seem to be some surplus of these components. If you make device for retro purposes (rather than functionality) you may look for partner in Russia sourcing and sending required components to you.
