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

Michael

  • Hi, Michael

    Could you show me those components not available, and the components your replacement.

    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.

  • In reply to michael coletti:

    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. 

  • In reply to Watermelon Noodles:

    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.          "

  • In reply to Watermelon Noodles:

    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,

    Michael

  • In reply to michael coletti:

    I think you already listed the substitutes as below

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

    Substitute       STP28N65M2

  • In reply to michael coletti:

    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.
