I think you may end up buying the whole faucet assembly. I may be wrong, but it can be really hard to find replacement parts for some assemblies that are simply cheaper and easier to replace. My go to is always Amazon because of the favorable shipping policies (I'm a Prime member.)
That being said, I think you shouldn't have any problem betting a new faucet for around $20.
I have a 2012 210UDS, haven't replaced the faucet yet. This one on Amazon looks like it might work:
