When necessary- used to express something definitely will occur that needs necessary action
If necessary- used to express something may or may not occur that needs necessary action (possible but not definite)
Ex.
When necessary, it okay to spend a lot of money.
If necessary, you should not hesitate to ask the teacher. (In this sentence it is not definite or not if the student needs help. They may or they may not.)
