At best you contact Fairchild and ask for successors. Sometimes the same internal structur from the old models is inside in SMD outline but completly other model number ("PZT" instead "2N" e. g. or completly other). Concerning the IRF130 ask International Rectifier. Semelab still offer successors to the old TO-3 ones as I know - check out the site of
TT electronics Semelab - Discrete Semiconductor Design, Packaging, Testing & Supply
Semelab - Mil/Aerospace Division - FETS, JFETs & IGBTs

Great idea I will do that also. Thanks
