MAGNETSYC
Offers higher current handling and lower DCR but requires a board redesign due to its larger package.
Finding a substitute for the TDK VLS3012HBX-2R2M 2.2µH inductor involves balancing its compact 3030 package with electrical performance. While no direct drop-in replacements were found, several functional alternatives offer superior current handling in different packages, requiring a board redesign.
Most alternatives are in larger packages, requiring a board redesign.
One form-fit candidate is a significant electrical downgrade. Others have different tolerances.
No direct, drop-in replacement was identified. The closest form-factor candidate is an electrical downgrade and requires careful validation.
Board redesign using a functional alternate with superior electricals (e.g., NR6045-2R2MTSX01).
Package incompatibility is the primary barrier to a drop-in replacement, requiring a PCB revision.

| Feature / factor | VLS3012HBX-2R2M | NR6045-2R2MTSX01 | SWPA5040S2R2NT | SFE3015A-2R2M-F-HF | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 3030 (3.0x3.0mm) | 6045 (6.0x6.0mm) | 5040 (5.0x5.0mm) | 3.0x3.0x1.5mm | 6045 (6.0x6.0mm) / 5040 (5.0x5.0mm) / 3.0x3.0x1.5mm — Not a drop-in replacement.; SWPA5040S2R2NT: Not a drop-in replacement.; SFE3015A-2R2M-F-HF: Slightly taller than target's 1.2mm max height. |
| Saturation Current | 3.35A | 7.92A | 5.5A | 2.0A | 7.92A / 5.5A / 2.0A — Significant upgrade.; SWPA5040S2R2NT: Upgrade.; SFE3015A-2R2M-F-HF: Significant downgrade, risk of saturation. |
| Current | 2.84A | 5.5A | 4.3A | 2.0A | 5.5A / 4.3A / 2.0A — Significant upgrade.; SWPA5040S2R2NT: Upgrade.; SFE3015A-2R2M-F-HF: Lower RMS current rating than target's 2.84A. |
| Dcr | 0.106Ω | 0.024Ω | - | 0.078Ω | 0.024Ω / 0.078Ω — Much lower DCR improves efficiency.; SFE3015A-2R2M-F-HF: Lower DCR improves efficiency. |
| Tolerance | ±20% | - | ±30% | - | ±30% — Wider tolerance may affect circuit performance. |
For new designs, parts like NR6045-2R2MTSX01 offer higher current ratings in a larger package. For existing layouts, SFE3015A-2R2M-F-HF has a similar footprint but lower current ratings, requiring careful electrical validation.
