yoyomac,
Yes, I have had some marginal success in resurrecting a Simasimac-prone SE/30 logic board by replacing the Bourns filter. But the replacement doesn't work for every single board; only a select few that have been recapped by me needed their RP2 replaced. I ended up salvaging replacement filters from off of a dead Mac SE logic board I had laying around. They match the exact same part as the original SE/30 filters.
Good luck trying to get new replacements from a parts vendor like Mouser or Digi-Key. They sell 'em, but you end up having to buy more than 150 quantity at about $2 or $3 each. It will be cheaper to either pull 'em from a dead SE or SE/30 logic board or build one from scratch, like described in the Repair Mac article. Use a chip socket and wire up your own shouldn't be hard, either. Oh, and if you do replace part for exact part, make sure you install a chip socket anyway. It makes replacing that filter much easier than having to desolder it out of a board. I've had my share (too many) of legs broken off during the extraction process.
