FHD4020S-1R5MT is same family and size but uses 1.5uH.
FHD4020S-2R2MT alternatives need FAE review. Current, inductance and 4020 pinout must be checked before substitution.
Isat, Irms or L differ.
4020 matches, pinout unchecked.
Passive part.
PDF check pending.
Direct replacement for FHD4020S-2R2MT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use YNR4020-2R2N only for derated current, or FHD4020S-1R5MT if 1.5uH is acceptable.
Inductance and current ratings are not fully aligned.

| Feature / factor | FHD4020S-2R2MT | YNR4020-2R2N | FHD4020S-1R5MT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Application | 2.2uH | 2.2uH | 1.5uH | 2.2uH / 1.5uH — same L; FHD4020S-1R5MT: lower L | |
| Tolerance | ±20% | ±30% | ±20% | ±30% / ±20% — wider spread; FHD4020S-1R5MT: same tol | |
| Current | 7.5A/4.8A | 3.4A/1.85A | 9.6A/6A | 3.4A/1.85A / 9.6A/6A — large derate; FHD4020S-1R5MT: higher ratings | |
| Resistance | 46/56mΩ | 40/52mΩ | 32mΩ typ | 40/52mΩ / 32mΩ typ — lower DCR; FHD4020S-1R5MT: lower DCR | |
| Package | 4020 4x4 | 4020 4x4 | 4020 4x4x2 | 4020 4x4 / 4020 4x4x2 — height 2mm; FHD4020S-1R5MT: same size | |
| Pinout | 2 pins | 2 pins | 2 pins | 2 pins — pinout unchecked; FHD4020S-1R5MT: pinout unchecked |
Verified drop-in options for FHD4020S-2R2MT 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.
