I ordered a couple timing belt idler pullies from a Lexus dealer online that have concerning part numbers on their packaging. For example:

Ordered: 13505-0F010

The box received has two part number labels, each with it's own bar code. One indicates "13505-50030", the other indicates "Supercedes 13505-0F010".

I'm reluctant to call the dealer I ordered the parts from, as if they're trying to clear their shelves of old parts I'm sure I'll be told "everything is fine". Kind of hard to trust impartiality.

I don't mind if it's the same part with a new part number, but if the -0F010 is an improved version and what the seller advertised, I think I'd rather have it.

Thoughts?

This site indicates that -0F010 replaces -50030

Which is correct? Time to make a phone call.
