Can I use IRF230 instead of 02N60P transistor?

i've been working on a PSU for about a week now, which i have no idea fixing.. im an engineering student and our instructor told us to bring and fix a PSU. he's a new a faculty and i think he's not aware about our subject offerings based on the current curriculum. to make things short, we're still taking basic elctronics along with his subject, the current lesson on the electronics were on diodes. and we have no idea how to fix this thing. i don't really know why nobody told our instructor about that, i guess we're all intimidated and now we've got huge problems.. hehe

but i think that's pretty normal on colleges and universities here, giving you a task which you have no clear idea of accomplishing, you just have to study it yourself.. so i did that, done some research bought a multimeter, soldering station and everything i need based on the data i've researched. i know the basic ohm's law. im aware that handling that PSU could be dangerous if not properly handled. i have an idea on how to test the components, (thanks to the internet also) so basically i think i've learn more or less enough information for me to wing this.

our PSU's problem was it was said that it was plugged into a 220v when it is rated 110v. well actually it's a computer PSU with a 110/220 toggle switch, it was turned on to the 110 part so when it was plugged and turned on, some white fumes, roasted corn like smell filled the room. so then i popped it open, saw two huge capacitors blown, so i unsoldered it, replaced with the same rating, minding the polarity i've managed to replaced it. but when i turned the power on, the fuse blows. so i assumed that the capacitors were a victim, there's something else greatly affected by the power surged that happened and blown the capacitors.. i checked the full wave diodes, it was ok.. next was the transistor, i unsoldered it from the board, and tested each of the 6 transistors, im not really quite sure, but the 3 transistors shows the same reading when tested. but the other 3 shows reading whichever way i connect the probes, i think it's shorted.. i salvaged another electronic device which has a transistor in it and tested it, just to make sure.. sure enough transistor must not show reading which ever you connect it, base, collector, emitter. so i bought some and the broken transistors..The 02N60P is an n-channel power mosfet and won't show the same kind of readings as a bipolar transistor. The transistor is probably one of two switching transistors in the PSU driven by a third.

the problem was i can't find 02N60P at any electronic parts shop. ask some higher students where to buy, been there, i think i've been to 5-6 places? it's either they don't have stocks, or they just don't sell those.

i've asked here and somebody told me to get IRF230 which is the closest. i searched for its datasheet they're not that similar but close plus they're not the same type, i don't know what it's called because im a freakin' dumb noob, but physically they're very different, i guess i just have to think of how i can properly attach it on the heat sink and board minding the proper terminals. if ever.

im really sorry for asking such questions, if i had known i really won't ask.. just also want to learn more and more..
the ratings of IRF230 and 02N60P were also not the same, excuse my english..
