AI Summary

RY3750 by RYCHIP: 1.2MHz Boost Adjustable 2.5V~30V 600mA SOT-23-5 Voltage Regulators - DC DC Switching Regulators RoHS.

The LT1613 from Analog Devices is a high-confidence, pin-compatible drop-in alternative to the RY3750 in a 5-lead SOT-23 package. It shares the exact same 1.23V feedback reference voltage, pin assignment, and switch voltage capability (up to 30V). Additionally, it offers an expanded input supply range of 1.1V to 10V and a comparable 1.4MHz switching frequency.

  • Pin-compatible drop-in alternative in a 5-pin SOT-23 package.
  • Exact 1.23V feedback reference voltage matches the target specification.
  • Wider input voltage supply range of 1.1V to 10V compared to 2.5V to 5.5V.

The AP3012 from Diodes Incorporated is a pin-compatible boost converter in SOT-23-5. It operates up to 29V output and accepts input voltages up to 16V, though its feedback voltage is 1.25V (versus 1.23V) and switch current limit is slightly lower at 500mA.

  • Pin-compatible drop-in layout in a 5-pin SOT-23 package.
  • Wider maximum input supply voltage rating up to 16V.
  • Feedback reference voltage is 1.25V compared to 1.23V, requiring minor resistor divider adjustment.
  • Slightly lower switch current limit: 500mA versus 600mA.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
