Fqa12p20 Fqa19n20c Discontinuation

Nelson Pass · 10th August 2009, 10:22 PM

One of my current favorite Mosfet pairs, the Fairchild FQA12P20 and
FQA19N20C are slated to be discontinued before the end of the year.

These have been the favored parts for the F5, as the P channel parts
have lower distortion, particularly for Common Source usage.

Mouser appears to be out of both.
Looks like Newark has 299 of the P channel right now.

I am sure members of the 2 GB's still have more than enough to spare.

I think a couple other similar devices have also been obsoleted -- sic transit gloria mundi

I happen to have some contacts in the excess inventory business and one says that they can get the FQA12P20 at $2/part with a $200 minimum so obviously 100 pieces. This is from what they call a reliable source that has qty 1000 on hand. I have no need for even 100 pieces but I thought I'd just mention it here to see if Nelson or anyone else is interested. I have no idea how reliable there so called "reliable" source is.

Pete, Who are they?

I probably should not have posted this publicly since another supplier might buy them up and jack up the price. I'll PM you.
