Part Number: TIDA-00951

Hello,

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?

Best regards

    Hi, Michael

    After looking through your list, only the MOSFET may have some effect to the efficiency, you can try that one.

    for the FIS1xx, it is an 50:1 current transformer. Please choose FIS105NL from PULSE.

    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?

    https://www.digikey.com/product-detail/en/alpha-omega-semiconductor-inc/AOT10N60/785-1191-5-ND/2353856 

    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

    best regards,

    I think you already listed the substitutes as below

    Obsolete        TK16E60W5,S1VX              Toshiba                          MOSFET, N-CH, 600 V, 915.6A, TO-220

    Substitute       STP28N65M2

    Hi, 

    For those magnetics compoents, you may contact Wurth Elek for samples or datasheet. 

    and for the Q10, you could choose AOT10N60 as the BoM listed.
