SEAWARD
A strong alternative in a compatible package with higher max voltage, but requires checking the higher min input voltage.
GM7350TB is a 40V, 200mA low quiescent current LDO in a SOT89-3 package. Alternatives exist with similar performance, but require careful review of input voltage range and package compatibility.
Input voltage range varies significantly across candidates and must be verified.
Several candidates share the SOT89 package, but pinout verification is still needed.
Not applicable for simple LDO regulators.
Direct replacement for GM7350TB should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SE8650K1-HF offers a similar form factor and an upgraded max input voltage, but its higher minimum input voltage (6V) must be checked.
The primary risk is mismatch in the input voltage range. Some alternatives have a lower maximum voltage, while others have a higher minimum voltage.

| Feature / factor | GM7350TB | SE8650K1-HF | SE8650X2-HF | ME6239A50PG | Compatibility / risk |
|---|---|---|---|---|---|
| Output Voltage V | 5.0 V | 5.0 V | 5.0 V | 5.0 V | 5.0 V — Output voltage matches.; SE8650X2-HF: Output voltage matches.; ME6239A50PG: Output voltage matches. |
| Voltage | 4.5 V to 40 V | 6.0 V to 80 V | Up to 80 V | Up to 30 V | 6.0 V to 80 V / Up to 80 V / Up to 30 V — Higher max voltage is an upgrade, but higher min voltage (6.0V vs 4.5V) is a risk.; SE8650X2-HF: Wider input voltage range is an upgrade.; ME6239A50PG: Maximum input voltage is lower (30V vs 40V), a critical downgrade. |
| Current | 0.2 A | 0.2 A | 0.2 A | 0.25 A | 0.2 A / 0.25 A — Output current matches.; SE8650X2-HF: Output current matches.; ME6239A50PG: Higher output current is an upgrade. |
| Package | SOT89-3(B) | SOT89-3 | SOT23-3 | SOT89-3 | SOT89-3 / SOT23-3 — Package is form-fit compatible, but pinout requires verification.; SE8650X2-HF: Different package requires board redesign.; ME6239A50PG: Package is form-fit compatible, but pinout requires verification. |
| Quiescent Current | 5 µA | 1.8 µA | - | - | 1.8 µA — Lower quiescent current is an improvement. |
Verified drop-in options for GM7350TB 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.
