The Complete Guide to Transistor Equivalents & Substitutions

When using an equivalent book, you must ensure the substitute matches the original in several key areas: Polarity and Type all transistor equivalent book

  • Polarity (NPN / PNP / N-channel / P-channel)
  • ( V_CEO ) & ( V_CBO ) (Voltage ratings)
  • ( I_C ) max (Collector/Drain current)
  • ( P_D ) (Power dissipation)
  • ( h_FE ) / ( \beta ) (DC current gain)
  • ( f_T ) (Transition frequency – for RF/switching)
  • Package type (TO-92, TO-220, SOT-23, etc.)
