I've said this before, so hopefully I don't come off as a broken record. However, I would never use derived columns in SSIS. Instead, I would use SQL. One advantage of this approach is I can see the data as I test. The other advantage is I am keeping my business logic in the same place as whatever is the source of the rest of the query.
Another advantage is that you don't have to use the awful one-line derived column editor 😀
