try fairchild or toshiba. also parts-express has a crossreference chart for semiconductors.

i have a big box of parts..Do you have a pic of what they look like ?

Are you sure they aren't IRFZ46N ? Where are they being used in the amp? Power supply fets I assume. What value are the gate resistors connected to them if they are power supply fets.

Not sure if the one in question is in this pic but these are what most look like

They will have the "model" number stamped/written on them.

A lot of the parts in that pic aren't even fets. Some of them are rectifiers and most of them are BJT's (bipolar junction transistor)

If you want take a pic of the parts in question and an overall pic of the amps circuit board and I will try to help you out. Even if originals aren't available there may be a good sub for those parts depending on where and how they are used in the amp. I am guessing though that you may have the number wrong.

Not trying to be mean to him but that dude probably has no idea what your talking about...

I hope he post some pics. I like helping out with this stuff.

What's your background? You obviously have some decent electronics knowledge...I'm a senior in Electrical Engineering so I've got a little knowledge myself

Actually I do know what he is talking about.

The pic was just for reference as this is what a lot look like but not all.

I just could not find a pic of the one he listed.

kudos to you bro, I'd wager that 99% of the members here wouldn't.

Background...... Well I took three years of electronics in highschool and a few basic electronics college courses. Been into car audio since before I could drive and about 5 years ago I started learning how to repair car amps through the help of Perry Babin on diyaudio.com and some self teaching. It helped a lot having a basic electronics knowledge when I started working on amps. After you get some of the basics down it's really easy to troubleshoot the problems in most amplifiers. Takes the right equipment though . You can get by with minimal stuff but the more equipment you have the easier it gets.

Wasn't trying to down you with my post. Just throwing the info out there for those who may not know what they are. Hate to see people get confused
