SHOU HAN
A functional alternative with higher current ratings and lower DCR, but in a different, larger package.
MDA1050-4R7M is a 4.7µH shielded power inductor in a 1050 package, rated for 16A Isat. Finding a direct drop-in replacement requires matching both the package and key electrical ratings.
All viable alternatives require a PCB layout change due to different package footprints.
Electrical parameters can be matched or improved, but one candidate has a lower current rating.
No direct pin-to-pin replacement was found. All candidates with matching inductance have different package sizes, requiring a board layout change.
Consider CYA1265-4.7UH for an electrical upgrade if a board redesign to accommodate a larger package is feasible.
The primary risk is the package mismatch. No candidates share the 1050 package with the required 4.7µH inductance.

| Feature / factor | MDA1050-4R7M | CYA1265-4.7UH | SMMS1360-4R7M | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Inductance | 4.7µH | 4.7µH | 4.7µH | 4.7µH — Inductance value matches.; SMMS1360-4R7M: Inductance value matches. | |
| Package | 1050 | 1265 | 1360 | 1265 / 1360 — Different, larger package requires board redesign.; SMMS1360-4R7M: Different package requires board redesign. | |
| Saturation Current A | 16A | 36A | 18A | 36A / 18A — Significantly higher saturation current.; SMMS1360-4R7M: Higher saturation current provides more margin. | |
| Current A | 15A | 18A | 13A | 18A / 13A — Higher temp. rise current is an upgrade.; SMMS1360-4R7M: Lower temp. rise current is a downgrade risk. | |
| Dcr Ohm | 9.3mΩ | 7.5mΩ | 6.8mΩ | 7.5mΩ / 6.8mΩ — Lower DCR improves efficiency.; SMMS1360-4R7M: Lower DCR improves efficiency. |
The best alternative is CYA1265-4.7UH, which offers superior current ratings and lower DCR. However, it is in a larger package and requires a board redesign.
