Irf9640

pnut028 · 14th January 2006, 09:20 AM

Does anyone know where I can pick up a couple of IRF9640 transistors? Or possibly a suitable replacement. They are part of a complementary pair irf640/9640 in a Rockford fosgate 801s. I have already replaced most of one channel, but cannot find a vendor with these in stock. Rockford will only sell the entire rail for more than the amp is worth.

Thanks,
Michael Hutchison

Did you check what the International Rectifier web site says about where to buy IRF9640?

http://ec.irf.com/v6/en/US/adirect/i...uctID=IRF9640:

Select our Country and click on "Check Availability".

In the US, it is available from Digikey IRF9640PBF and Newark 06F8492 in single quanities for ~$2 each.

BTW, Fairchild Semi SFP9640 is a substitute but not recommended for new designs, so may be hard to find.
