    To the author: the exchange helped? in the sense - is the new mosfet more vital?

    Replaced by Piotr for now works well for a week, I also put in a better, bigger cooling from an old computer power supply, thanks to which the mosfet does not heat up as much as I went through the check, the original lasted 2 weeks, but as you can see the photos had very poor cooling, so you can easily use this replacement.

    The replacement works very well.

    Using a Google translator. Please forgive me for any mistakes.

    Are you looking for a replacement for 200N03A. Very rare, you can not find a datasheet.
    Used in car modules for children, the "Weelye" brand.

    Will IRF3305 work as a replacement for 200N03A?

    Help me find a replacement or equivalent part number.

    Unfortunately, UTT200N03 is available only in wholesale from China, you can not find it anywhere else.

    I replaced IRFz44N, but the Soft-Start function has disappeared and the circuit does not respond to speed control. The engines always have full power.
    When 200N03A was put down, it worked properly. I do not know why spare part numbers do not respond to gate pulses (PWM / analog).

    Could you tell me which company is producing these mosfets with the "CR" logo on the component? I asked many sellers, but nobody knows. They only know that it's done in China.

    Between 150N03A is available here: https://thienduongcuabe.com/linh-kien-xe-dien-tre-em-tranzitor-150n03a
    But it's a Vietnam seller and they do not send international.

    IRF is not suitable, it has too much value Rdson.

    I wrote to you to try IRL3713 or IRL1404Z.
    You can try IRL3713 or IRL1404Z.

    Logo "CR" - I saw this logo, but unfortunately I do not remember.

    Sure. I will try to update them both. I hope I can find them locally, wait a long time.
    Thank you

    I would like OP to react and update if its Soft-Start function worked after the exchange with IRF3305.

    For me this replacement IRF3305PBF works until now, I note that I gave it better cooling and it works until today

    Thank you for your response. Does the Soft-Start function work correctly after installing IRF3305PBF?

    As far as the Soft-start function is concerned, it works properly, there are no jerks, the car moves smoothly, the only minus is that in the first and second gear if there is a greater load, the car moves under the hill, it throws gears and blocks the car for 5 seconds from the third gear he goes without problems. But the smooth start function works in every gear
