Hi,
there are no golden replacement options, everyone has to choose what they can purchase, the situation with component availability is really bad in these days. With our redesigns we use as MPS as favorite supplier, but they do not have all needed replacement parts, so we may also use parts from other vendors.
TEBF0808 new version schematic will be available too, in some time, so you can see what replacements we use.
as one for all replacement we use MPS3834 where ever it fits in.
