Application Scenarios & Design Considerations

PNP Epitaxial Silicon Transistor

Alternative Part Number

  • 2N4403 --: Industry-standard PNP general-purpose transistor with the same electrical role as the KST4403; widely available and pin-compatible in most TO-92 circuits.
  • MMBT4403 --: SMD PNP transistor equivalent to the 4403 family, suitable when a surface-mount replacement is acceptable and offering similar current and voltage ratings.
  • BC557 --: Common PNP general-purpose transistor with comparable voltage and current ratings, usable as a functional substitute in many low-power switching and amplifier applications.
  • MMBT4403LT1G --: PNP general-purpose transistor with the same 40V/600mA ratings and SOT-23 package, widely available and a direct functional replacement.
  • BC807-40 --: PNP transistor in SOT-23 with 45V/500mA ratings, close enough for most KST4403 applications and easily sourced.
