Vishay
Pin-compatible alternative from the same manufacturer with lower current handling and higher resistance.
Finding a replacement for the Vishay IHLP2020CZER2R2M11 2.2µH inductor involves balancing package size, current ratings, and DCR. Alternatives exist but require careful verification of thermal performance and footprint compatibility.
Most alternatives have weaker current or DCR specs.
Several candidates have similar or identical footprints.
Multiple vendors offer parts in this category.
No direct drop-in replacement with identical or better performance was found. The closest is IHLP2020BZER2R2M11, but it's a downgrade in current handling.
The IHLP2020BZER2R2M11 is pin-compatible but has a lower current rating. For a potential upgrade, SMMS0530-2R2M offers higher saturation current but needs footprint and thermal checks.
The primary risk is thermal. Many alternatives have lower heat rating current (Irms) or higher DCR, which can lead to overheating and reduced efficiency.

| Feature / factor | IHLP2020CZER2R2M11 | IHLP2020BZER2R2M11 | SMMS0530-2R2M | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 2020 (5.18 mm x 5.49 mm) | 2020 | 0530 (5.7x5.2mm) | 2020 / 0530 (5.7x5.2mm) — Package matches, likely pin-compatible.; SMMS0530-2R2M: Very similar size, footprint likely compatible but needs verification. | |
| Inductance | 2.2 µH | 2.2 µH | - | 2.2 µH — matched | |
| Current | 5.5 A | 5.5 A | 6.5 A | 5.5 A / 6.5 A — Saturation current matches.; SMMS0530-2R2M: Heat rating current is slightly lower. | |
| Dcr | 22.5 mΩ | 34.9 mΩ | 31 mΩ | 34.9 mΩ / 31 mΩ — Higher DCR will increase power loss.; SMMS0530-2R2M: Higher DCR will increase power loss. |
There is no single 'best' alternative. IHLP2020BZER2R2M11 is pin-compatible but a downgrade. SMMS0530-2R2M is a potential upgrade but requires footprint and thermal validation. The choice depends on your design's tolerance for changes in performance and layout.
