AO3413 is an active SOT-23 P-MOSFET candidate with derating risk.
IRLML6402 is an active SOT-23 P-channel MOSFET. Alternatives need pinout, current, RDS(on), and thermal checks.
RDS(on) and current may be weaker.
SOT-23 matches, pinout not proven.
Discrete MOSFET; no firmware.
Some candidates are obsolete or NRND.
No pin-compatible replacement is proven from the provided data.
AO3413 is the best active catalog candidate, only for derated loads.
Target pin_count and pinout are missing.

| Feature / factor | IRLML6402 | AO3413 | AO3409 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SOT-23 | SOT-23 | SOT-23 | SOT-23 — same package name; AO3409: same package name | |
| Pinout | pin_count missing | 3 pins | 3 pins | 3 pins — no pin map; AO3409: no pin map | |
| Voltage | -20 V | -20 V | -30 V | -20 V / -30 V — no 1.1x margin; AO3409: higher VDS | |
| Current | -3.7 A | -3 A | -2.6 A | -3 A / -2.6 A — lower ID; AO3409: lower ID | |
| Power | 1.1 W | 1.4 W | - | 1.4 W — higher PD | |
| Lifecycle | Active | - | NRND | NRND — not for new designs |
AO3413 is the best active candidate here, but it is lower current and needs FAE review.
