Strong parametric match with higher input voltage (65V) and output current (200mA) in the same package.
SSP7985P33PR is a 60V, 150mA low-power LDO in a SOT89-3 package. Its key feature is a very low 2µA quiescent current, making it ideal for battery-powered and always-on systems.
Some alternatives have lower input voltage ratings that must be checked against the application's requirements.
SOT89-3 is a standard package, but pinout configurations can vary between manufacturers. Verification is required.
Direct replacement for SSP7985P33PR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SE8633K2-HF offers superior voltage and current ratings in the same package, making it the most promising alternative.
The primary risk is using a substitute with a lower maximum input voltage, which could damage the part in high-voltage applications.

| Feature / factor | SSP7985P33PR | SE8633K2-HF | TPL820F33-89TR | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT89-3 | SOT89-3 | SOT89-3 | SOT89-3 — Package matches, but pinout requires verification.; TPL820F33-89TR: Package matches, but pinout requires verification. | |
| Voltage | 5V to 60V | 4.3V to 65V | 3.6V to 42V | 4.3V to 65V / 3.6V to 42V — Wider input voltage range covers and exceeds target.; TPL820F33-89TR: Candidate has lower max input voltage. | |
| Current | 150mA | 200mA | 180mA | 200mA / 180mA — Higher output current capability.; TPL820F33-89TR: Higher output current capability. | |
| Quiescent Current | 2µA | 1.8µA | 2µA | 1.8µA / 2µA — Slightly lower quiescent current.; TPL820F33-89TR: Low quiescent current matches target. |
Verified drop-in options for SSP7985P33PR are limited in the current batch. Review candidates marked Strong match or Datasheet verified, and validate package, pinout, and electrical limits before committing a BOM change.
