Alternative Part Number

  • 2SC457C --: Japanese 2SC-series NPN transistor with similar low-power audio/small-signal characteristics and the same 457 type number, widely available as a direct functional substitute.
  • BC547C --: General-purpose NPN small-signal transistor with comparable current gain and voltage ratings, commonly used as a cross-reference for low-power SK transistor types.
  • 2N3904 --: Very common general-purpose NPN transistor with similar small-signal switching and amplification specs, suitable as a fallback replacement when exact SK types are unavailable.
  • 2SC4572 --: Similar NPN power transistor in the same Sanken family with comparable voltage and current ratings, suitable as a functional substitute.
  • 2SD1047 --: NPN power transistor with similar power dissipation and current capability, commonly used in audio and general switching applications.
  • MJE15032 --: Widely available NPN power transistor with comparable ratings, offering a cross-manufacturer alternative for the original Sanken device.
