Mam teraz dylemat, schemat którego używam jest od innej płyty, PQ301 oraz PQ303 są oznaczone na nim jako MDU1512RH(PQ301) oraz AON7506(PQ303). Po wylutowaniu z płyty PQ301 to AON6426 a z PQ303 udało mi się odczytać aby numer V1526 co by wskazywało na to że to MDV1526 jeśli dobrze myślę. W takim wypadku należy szukać mosfetów o identycznych parametrach czy mogą być one zbliżone? Udało mi się znaleźć coś takiego jeśli chodzi o ten AON6426
