Alternative Part Number

  • L4973D5.1 --: Monolithic step-down switching regulator with comparable input voltage range and current capability, suitable as a functional replacement in similar power supply designs.
  • LM2596S-5.0 --: Widely available step-down regulator with similar voltage/current ratings and simple external component requirements, making it a practical drop-in alternative.
  • MC34063A --: Versatile DC-DC converter IC covering similar input/output ranges, commonly used as a general-purpose substitute when exact Sanken part is unavailable.
  • S-8120S --: Same 8120S series low-dropout voltage regulator with identical pinout and function; Seiko is the original source of the SI-8120S marking.
  • S-812C50AMC --: ABLIC (formerly Seiko) S-812C series LDO regulator with comparable output current and voltage options, direct functional replacement.
  • MCP1700-5002E --: Low quiescent current LDO regulator with similar 5V/250mA class ratings, widely available and pin-compatible in SOT-23 packages.
  • L5973D --: Step-down switching regulator with comparable input voltage range and current capability, widely available and pin-compatible in function.
  • LM2596S-ADJ --: Adjustable buck regulator with similar voltage and current ratings, very common and well-documented alternative.
