i looked at the BOM files and i noticed that some of the components are not available for sale any more.
How can I replace them?

Hi thank you for replying!
i am a student that want to build that unit , and i am little bit lack of confident to choose substitute myself.
thank you for the help.

Another question - i am not sure what the xx is stand for - since i cannot find this part at Coilcaft website i am asking that question.
T3 xx mH FIS1xx Coilcaft Transformer, Current Sense 0.591 x 0.693 inch
Hi thank you for the answer~!
did you add a link or a serial number for new part or that you suggest that i will use the one that i mention?
" After looking through your list, only the MOSFET may have some effect to the efficiency, you can try that one. "
also there is an alternative for those transformers? i find it difficult to get them.
|T1||1||750343383R01||Wurth Elektronics||TRANSFORMER, 4.5uH, 10%, THRU-8P|
|T2||1||750343382R02||Wurth Elektronics||TRANSFORMER, 45uH, THRU-20P|
|T4||1||38uH||750343341||Wurth Elektronik||Transformer, 50 uH, SMT|
as well as , is that component ok for use?
note that the current is 10A and not 2A as mention in BOM.
as a replacement for :
|Q10||1||600V||AOT10N60||AOS||MOSFET, N-CH, 600 V, 2 A, DPAK|
