Alternative Part Number

  • 2SC5118 --: Similar NPN transistor in the same 5118 numbering family with comparable voltage and current ratings, widely available as a drop-in for many SK small-signal applications.
  • BC337 --: General-purpose NPN transistor with similar current gain and switching characteristics, commonly used as a substitute for small-signal SK parts in low-power circuits.
  • 2N3904 --: Very common general-purpose NPN transistor with comparable small-signal switching performance, easy to source and often used where SK small-signal devices are unavailable.
  • 2SC3356 --: Low-noise NPN RF transistor in a similar SOT-23 package, widely used as a general replacement for small-signal RF amplifiers.
  • BFR93A --: NPN RF transistor with comparable gain and frequency performance, commonly cross-referenced for small-signal RF applications.
  • MMBT918 --: General-purpose NPN RF transistor in SOT-23, suitable as a functional substitute where exact SMA5118 specs are not critical.
