Is there a website that will tell you what class number on one campus is equivalent to what other class number but on a different campus?
My department has a transfer credit evaluation committee whose job is to decide which of our requirements are satisfied by classes taken elsewhere (usually other universities, not just other campuses).  On that basis, I guess that your department has a similar committee. If you had not bothered to check  for equivalent courses but had just taken one and thought it would be equivalent (not a recommended course of action) and had then come back to your home campus and announced "I've fulfilled all the requirements; give me my diploma," then there would be some person or committee whose job is to say "Whoa; who says that this course satisfies our requirement? That's for us to decide, not you." I suggest that you ask enough questions (of your department chair, or dean, or secretaries) to find that person or committee and then ask them what courses would satisfy the requirement. In other words, get an authoritative answer from someone who has the real authority to approve (or disapprove) using a course from elsewhre to fulfill your requirement.
