Return Value if NULL condition in SQL Query

How can I modify this CASE WHEN statement when the value is NULL? I need to show '01' instead of the records returning an NULL value.
Right now some records show a result of NULL and I want to have it show '01' instead of NULL


CASE WHEN ISNULL(P.MinProdCL, '') 
                         = '' THEN P2.MinProdCL ELSE P.MinProdCL END AS NewProdCLFinal

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

COALESCE(P.MinProdCL, P2.MinProdCL, '01')

The COALESCE function accepts an arbitrary number of arguments and returns the first non-null value.

And when it is not null, it will return P.MinProdCL

With Russ' solution, you even don't need to use case:

COALESCE(P.MinProdCL, '01')
