The Panthers stormed back after spotting the Devils an early 3-0 lead.
Sean Bergenheim and Jason Garrison netted power-play goals 3 1/2 minutes apart late in the first period, and Mike Weaver collected the equalizer 2:18 into the middle frame.
Less than 4 minutes later, New Jersey's Petr Sykora was whistled for high-sticking and Campbell tallied on the resulting power play.
The Panthers hung on the rest of the way to grab a 2-games-to-1 lead in their best-of-seven Eastern Conference quarterfinal series.
The Devils will try to even the series Thursday in Game 4.
