Alternative Part Number

  • TB62746AFG --: Same-series LED driver from Toshiba with comparable channel count and current capability, often used as a direct functional substitute.
  • STP16CP05 --: Constant-current LED sink driver with similar output channels and current range, suitable for LED display and lighting applications.
  • MBI5026 --: Widely used 16-channel constant-current LED driver with similar functionality and electrical characteristics, commonly cross-referenced for LED panel designs.
  • TB6612FNG --: Dual H-bridge motor driver IC in a similar small package, widely used as a drop-in functional substitute for motor drive applications.
  • DRV8833 --: Dual low-voltage H-bridge motor driver with comparable current and voltage ratings, common cross-brand alternative for similar driver functions.
  • L293D --: Classic quad half-H driver with similar logic-level control interface, widely available and often used when the original driver is unavailable.
  • STP16CP05MTR --: Constant-current LED sink driver with 16 channels and serial interface, functionally similar to the TCA62746AFG and widely available from a different manufacturer.
  • TLC5928IDR --: 16-channel constant-current LED driver with serial control, offering similar drive current and logic interface, suitable as a cross-manufacturer alternative.
  • L298N --: Classic dual full-bridge motor driver with higher voltage/current headroom; usable as a drop-in functional substitute when board space allows.
