A5vnb mosfet

need to find something compatible was thinking the NTMTS001N06CTXG

Sorry, we would need more information to be able to give you any opinion on your choice. “A5vnb” does not appear to be a complete part number. Is “A5vnb” the marking on the package? What, specifically, is marked on the package, and in what arrangement (if multiple rows)? Do you have an image you can post to help in identification? What are the dimensions of the part?
