Application Scenarios & Design Considerations

NPN Epitaxial Silicon Transistor

Alternative Part Number

  • 2N3904 --: General-purpose NPN transistor in TO-92, widely used as a functional substitute for small-signal switching applications similar to the KSR1203.
  • BC547 --: Low-power NPN transistor with comparable current and voltage ratings, commonly used as a drop-in replacement in switching and amplifier circuits.
  • MMBT3904 --: SMD NPN transistor equivalent to the 2N3904, suitable when a surface-mount alternative to the KSR1203 is needed.
