FWIW
People have doubts about things. Doubting requires thinking. It is an expression of disbelief.
A component does not think, so it can not have or express doubt.
A better title would be "question about component" or "what is this component".
Correct uses of doubt.
I doubt that I will live to be 150 years old.
I doubt that man will go to mars in my life time.
She doubted me when I said, I am the king of Texas.
It is doubtful that we will be killed by lighting.
No criticism intended.
