IRF3305PBF - is available for purchase from TME

Bazic · Answer

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

mc-giwer · Answer

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.

Probably a type similar to: UTT200N03 You can try to replace eg: IRL3713 IRL1404Z

sandyx · Answer

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: But it's a Vietnam seller and they do not send international.

IRFZ44N is not suitable, it has too high Rdson value.
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.

mc-giwer · Answer

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

sandyx · Answer

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

mc-giwer · Answer

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
