You mean due to vs because of ?

here is the usage of them,

clause <because of> noun
noun <due to> noun

Regards,

clause <because of> noun
noun <due to> noun

This is correct. A few examples to clarify:

The flood was due to excessive rain. Correct: "due to" modifies the noun "flood." (One helpful hint: if "due to" is correct, you can typically substitute the phrase "caused by," and the sentence will still be coherent. "The flood was caused by excessive rain.")

I was late to work due to heavy traffic on the highway. Incorrect: "due to" must modify a noun. Here it seems to modify the clause "I was late to work." (Notice: "I was late to work caused by heavy traffic on the highway," is incoherent. It sounds like "work" was caused by "heavy traffic.")

I was late to work because of heavy traffic on the highway. Correct. "Because of" modifies the previous clause.

Due to X is an ADJECTIVE.
It serves to modify a NOUN.
The cancellation was due to rain.
What KIND of cancellation?
The cancellation DUE TO RAIN.
When due to is used correctly, it can be replaced by caused by.
The cancellation was CAUSED BY rain.

Incorrect: The game was canceled due to rain.
Here, due to cannot be replaced by caused by:
The game was canceled caused by rain.
Doesn't work.

Because of X is an ADVERB.
It serves to modify a VERB.
The game was canceled because of rain.
WHY was the game canceled?
BECAUSE OF RAIN.
