Can it be replaced directly?

No verified pin-compatible replacement is supported by the provided fields.

Best replacement path

Use a boost converter with 2.5-5.5V input, 28V output rating, 1.5A switch limit, and verified pinout.

Main risk

Most candidates are buck or LDO parts, not boost converters.
