Hello , I am having a problem finding and getting a Bipolar transistor 2n3904bu for my softie 3 build . On the mouser cart it says back ordered 43 weeks . I searched around and only could find them on amazon (at 6.00 to 12.00 each . little pricey ) and on amazon it says 2n3904 without the bu on the it . As I am not educated in electronics , I do not know the difference of the parts I'm looking at . Can someone please advise ?
2n4904 should be fine. I've never had an issue. Last ones I bought came from ebay.
