Skibane,
A great step-by-step guide!
I checked with Mouser's web page & emailed them but they now have a minimum order qty of >400 each (Fairchild 512-FDH5500 is obsolete) for 512-FDH5500-F085 as a replacement.
Two questions since you are an expert:1) Have you found the Fairchild MOSFET to be a reliable replacement after having it installed some time?a. I cannot find an alternate source via Google to Mouser not requiring a min. order for the Fairchild component can you think of an alternate source?
2) Alternatively on the Maxima.org site there was a post by someone who suggested an NEC 2sk2500 replacement to be a Fuji Electronics 2sk2690 (their post below). Since I’m not an expert in reading MOSFET specs, in your opinion would the Fuji MOSFET from Allied electronics, be a reliable replacement option for the FDH-5500?
