MosFETs for Rockford 1000x2

[mifflinsharks72]

I have a Rockford 1000x2 that has a blown output mosfet. The part # is Irf6218, this part is discontinued there are some on eBay and Amazon but I’m concerned with getting fakes. Does anyone know of a suitable replacement or a reputable source for the 6218?

Is this your amp or is it for a customer?

What's the PC# on the board?

Rochester shows stock. I never used them as a supplier but I've seen Digikey sell parts through them. That doesn't include this part but I'd trust Rochester over eBay or Amazon.

I attached a photo of the board#. It’s my amp.

 

[Perry Babin]

OK. II don't have a diagram for that amp.

What's the rail voltage in the amp?

Replace all with IPP200N15N3G or IPP320N or FDP42AN15A0

We keep all these parts in stock in addition to thousands of IRF3205

I've used Rochester many times. They have always sold good reliable components.

Thanks for the replies.
Perry, the rail voltage is 57 volts.

Moer, I looked at those the irf6218 is a p-channel those are n-channels does that make a difference?

Sean, I was under the impression that Rochester will not sell to individuals. I would like to use them, did you purchase direct from them ?

I have purchased directly from them numerous times. You have to register for an account, and be sure to fill in all information in the registering process. They will then send you an email with a link to set up a password. Click the link and set your password and your ready to order.

The reason I asked is because, if there was no viable solution, you could reduce the rail voltage to a point where a 100v FET would work. There's no reason to consider this if the 6218 is available from a reputable distributor.
