And you do remember how well they worked, right? What I’m trying to say is that unless you know why the original units failed, just replacing them does not address the reason for the failure, and it may well recur. Unless you can be sure that both transistors are way over-spec’d for this application, you must care about the differences between them. Are you certain that at the current levels this FET will be operating under that you can afford almost 2x the power dissipation?
I suggest finding a better FET, there are literally thousands of them in that package that would do the job at least datzsheet well as the OEM solution, if not better.

It’s generally not a good idea to under-spec a replacement part, dqtasheet if the original failed in the application it was designed for. Thank you for your interest in this question.

Here is the question: Can I replace it without major consequences? Thank you for your answer.

Ricardo 4, 14 37 Mark Jhomel Olimon 11 1 4. It would be polite to link to the datasheets for both parts. That would encourage people to look at them to help you. It would be better practice to show why you think this replacement might work, and ask about any aspects you are unclear on.
That shows effort, that you have tried to find your own answer, instead of laziness. WhatRoughBeast 49k 2 28 Sir I was an IT student but I want to repair my Amplifier on my own, I knew a lot of things about basic electronics, however, I failed many times in troubleshooting an amplifier. Only the positive rail of the SMPS are cooked, but the negative rails are still in good condition.
So why is that sir? Dxtasheet on resistance is not the same. If this was already a way over spec’d part it would be one thing, but this is likely not true in a power supply this answer is incorrect.
MarkJhomelOlimon – Sorry, I’m not psychic. Obviously the upper units cooked because they got hot.

This suggests that the gate drive circuitry and n-type MOSFETs used on the upper rails need special bootstrapped drivers is getting flakey. Or do you know for certain what those values are? Carry on, while I go over here and hide. I had the wrong datasheet. Don’t care about their difference in power.
Brendan Simpson 1, 3 I guess that something’s wrecked the rail.
