Application Scenarios & Design Considerations

Separate Excitation Switching Type

Alternative Part Number

  • STR7102F --: Same STR7 series switching regulator with isolated suffix variant, similar electrical ratings and pinout, direct functional replacement.
  • STR7103 --: Adjacent part in the STR7 series with comparable voltage/current capability, usable as a close substitute with minor parameter differences.
  • STR7102D --: Another STR7 series variant offering similar regulation characteristics, suitable when the exact original is unavailable.
  • STR-A6252 --: Offline PWM switching regulator IC in the STR-A series with similar primary-side regulation function; a common substitute for STR7xxx offline switchers.
  • STR-W6756 --: STR-W series offline switching regulator with comparable power handling and built-in MOSFET, suitable as a functional replacement in SMPS designs.
  • ICE3B0565 --: Integrated offline SMPS current-mode controller with built-in CoolMOS, widely used as a cross-vendor alternative for small offline flyback supplies.
