Replacement Logic

java
// 1N400x: higher voltage can replace lower
"1N4007" can replace "1N4001" through "1N4007"

// MMBT equivalent to 2N
"MMBT2222" == "2N2222"
"MMBT3904" == "2N3904"

// Signal diode equivalents
"1N4148" == "1N914"

// SS series: higher current can replace lower
"SS34" can replace "SS14" (same voltage, higher current)

Learnings & Edge Cases

  • 1N400x voltage order: 1N4001=50V, 1N4002=100V, ..., 1N4007=1000V. The digit maps to voltage rating.
  • 1N540x voltage order: 1N5400=50V, 1N5401=100V, ..., 1N5408=800V. Similar pattern but different mapping.
  • MMBT vs 2N: MMBT is the SMD (SOT-23) equivalent of 2N through-hole transistors. Same electrical specs, different package.
  • PN vs 2N: PN series (PN2222) is plastic-packaged version of 2N series. Generally interchangeable with 2N.
  • 1N4148 vs 1N914: These are electrically equivalent signal diodes. Can be used interchangeably.
  • SS current rating: First digit indicates current (SS14=1A, SS34=3A). Higher current can replace lower.
  • S80xx/S90xx series: Common in Asian markets. S8050/S8550 are general purpose NPN/PNP pairs.
  • BAV70/BAV99: Dual diode packages (SOT-23). BAV70 = common cathode, BAV99 = series pair.
