Offers higher current ratings in a larger physical package, suitable as a functional upgrade.
Finding a substitute for the APV ANR3015T330M, a compact 33µH power inductor, involves balancing electrical needs with physical constraints. While several parts offer superior electrical performance, they come in much larger packages.
All candidates are in much larger packages (e.g., 7x7mm vs 3x3mm) and require a new PCB layout.
All candidates offer superior current handling and lower DCR, representing an electrical upgrade.
No, a direct, pin-compatible replacement for ANR3015T330M was not found among the reviewed candidates. All alternatives are physically much larger.
The best path is to select a functional upgrade from the candidates and redesign the PCB layout to accommodate the larger package. This will also improve electrical performance.
The primary risk is the significant package size difference, which makes these parts physically incompatible without a board redesign.

| Feature / factor | ANR3015T330M | FAUL0640-330MT | FXL1050-330-M | FXL1365-330-M | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 3.0x3.0x1.5mm | 6.6x7.0mm | 10x11.5mm | 13.45x12.6mm | 6.6x7.0mm / 10x11.5mm / 13.45x12.6mm / 7.1x6.6mm — Candidate is substantially larger and requires board redesign.; FXL1050-330-M: Candidate is substantially larger and requires board redesign.; FXL1365-330-M: Candidate is substantially larger and requires board redesign.; SMS0650-330MT: Candidate is substantially larger and requires board redesign. |
| Current | 0.44A | 2.2A | 4.2A | 6.5A | 2.2A / 4.2A / 6.5A / 2.8A — Significantly higher current rating (Irms).; FXL1050-330-M: Significantly higher current rating (Irms).; FXL1365-330-M: Significantly higher current rating (Irms).; SMS0650-330MT: Significantly higher current rating (Irms). |
| Saturation Current A | 0.45A | 3.0A | 5.2A | 8.0A | 3.0A / 5.2A / 8.0A / 3.3A — Significantly higher saturation current.; FXL1050-330-M: Significantly higher saturation current.; FXL1365-330-M: Significantly higher saturation current.; SMS0650-330MT: Significantly higher saturation current. |
| Dcr Ohm | 1066mΩ | 240mΩ | 86mΩ | 65mΩ | 240mΩ / 86mΩ / 65mΩ / 150mΩ — Much lower DCR results in less power loss.; FXL1050-330-M: Much lower DCR results in less power loss.; FXL1365-330-M: Much lower DCR results in less power loss.; SMS0650-330MT: Much lower DCR results in less power loss. |
The best alternatives are functional upgrades like the SMS0650-330MT or FAUL0640-330MT. They offer better electrical performance but require a PCB redesign due to their larger size.
