IRFP064N Question

mike49504 · 23rd December 2010, 06:26 PM

I was told that the HUF75344G3 is a drop in replacement for the IRFP064N's .

Just wanted to double check to see if this is true?

They're approximately equivalent and would likely be interchangeable in most switching power supplies. Why would you want to use them if the originals were 064s?

mike49504 · 23rd December 2010, 06:53 PM

Cause no one has stock on the IRFP064N's Unless you know of a place ?

Digikey - no stock
Mouser-no stock
Allied electronics- no stock
Future electronics- no stock

Arrow Electronics | Electronic Components | - North American Components (NAC)

400+ in stock.

Register with them and the price will be better by ~20%.

Thanks Perry,

Now what about the IRFP360LC's LOL can not find them anywhere .
I know of a couple of places that have the 360's but not the 360lc's .
And im not sure if the 360's will work. Any thoughts?

Ok thanks.

I other part im looking for. KA78T12 Know of any sources for that?

I use AVNET all the time, best place to find ultra fast vishay/telefunken diodes

NOS naturally!

IIRC the KA78T class was just your run of the mill to-220 positive voltage regulator, Just about any 7812 will fit the bill Id bet, unless they were really sourcing 3 amps from that little guy!

Perry Babin · 23rd December 2010, 10:10 PM

I couldn't find anything but there are several manufacturers and they all use different prefixes. Using only 78T12 may help when searching.

I don't generally like to see anyone buy electronic components from eBay but the following seller seems to be OK (from what I've heard from those who have purchased items from them).
78T12 Integrated Circuit x 1 pieces on eBay.ca (item 380293069690 end time 26-Dec-10 07:45:12 EST)
