A form-fit compatible alternative with higher current ratings and a slightly higher DCR in a lower profile package.
Finding a substitute for the FXL0650-150-M 15µH power inductor involves matching its 7.0x6.6mm package, 2.6A current rating, and 90mΩ DCR. Several alternatives exist with varying performance and package compatibility.
Several alternatives have different footprints, requiring a PCB redesign.
Some options have lower current ratings or higher DCR, impacting performance and thermals.
No verified direct drop-in replacement is available. FXL0640-150-M is the closest form-fit candidate but has a slightly higher DCR and different height that requires review.
FXL0640-150-M offers a similar footprint with upgraded current ratings, making it a strong candidate. Functional alternatives exist but require board redesign.
The main risks are package incompatibility for functional alternates and reduced current handling (Irms) for some form-fit options.

| Feature / factor | FXL0650-150-M | FXL0640-150-M | FXC1040-150M | FXL0840-150-M | Compatibility / risk |
|---|---|---|---|---|---|
| Package | SMD, 7.0x6.6mm | SMD, 7.0mm x 6.6mm | 11.5mm x 10.3mm x 4.0mm | SMD, 8.8mm x 8.2mm | SMD, 7.0mm x 6.6mm / 11.5mm x 10.3mm x 4.0mm / SMD, 8.8mm x 8.2mm / SMD, 13.45mm x 12.6mm — Footprint matches, but height is 4.0mm vs 5.0mm.; FXC1040-150M: Larger footprint requires board redesign.; FXL0840-150-M: Larger footprint requires board redesign.; FXL1360-150-M: Much larger footprint requires board redesign. |
| Current | 2.6 A | 3.7 A | 6.25 A | 4.8 A | 3.7 A / 6.25 A / 4.8 A / 4.9 A — Higher rated current provides more margin.; FXC1040-150M: Significantly higher current rating.; FXL0840-150-M: Significantly higher current rating.; FXL1360-150-M: Significantly higher current rating. |
| Saturation Current A | 3.2 A | 4.5 A | - | - | 4.5 A — Higher saturation current is an upgrade. |
| Dcr Ohm | 90 mΩ | 95 mΩ | 45 mΩ | 71 mΩ | 95 mΩ / 45 mΩ / 71 mΩ / 29 mΩ — Slightly higher DCR may be acceptable.; FXC1040-150M: Much lower DCR improves efficiency.; FXL0840-150-M: Lower DCR improves efficiency.; FXL1360-150-M: Much lower DCR improves efficiency. |
FXL0640-150-M is a strong candidate, offering a compatible footprint with higher current ratings. However, its slightly higher DCR and different height should be verified for your application.
