Need some tube advice, non 18 watt

My 5y3 for my Champ just gave up on me and I dont have any on hand, but I do have a couple of 5u4's.
Could these be allright to use?

No.. heater current is much more for the 5u4.. and your voltage would also rise quite a bit. I would not suggest useing it. 5y3s are plentyful,and NOS aren't that much.
