Same package and family, but lower current rating, higher DCR, and different inductance. Engineering review is essential.
Finding a substitute for the CYH125-68UH 68µH power inductor involves balancing inductance, current rating, and package size. While no direct drop-in replacements were found, several alternatives exist with varying trade-offs requiring review.
Candidates have different inductance and/or lower current ratings.
Candidates have identical or very similar footprints.
No direct, drop-in replacement for the CYH125-68UH was identified. All candidates require engineering validation due to differences in key electrical parameters like inductance or current rating.
Review MS127-330MT for its matching current/DCR, or CYH125-100UH for its matching package from the same family.
The primary risk is functional failure or damage due to mismatched inductance or a lower current rating in the replacement part.

| Feature / factor | CYH125-68UH | CYH125-100UH | MS127-330MT | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Inductance | 68 µH | 100 µH | 33 µH | 100 µH / 33 µH — Higher inductance, affects circuit function.; MS127-330MT: Significantly lower, affects circuit function. | |
| Current | 3.0 A | 2.5 A | 3.0 A | 2.5 A / 3.0 A — Lower current rating is a downgrade risk.; MS127-330MT: Rated current matches target. | |
| Resistance | 0.0648 Ω | 0.1 Ω | 0.0648 Ω | 0.1 Ω / 0.0648 Ω — Higher DCR will increase losses.; MS127-330MT: DC Resistance (DCR) matches target. | |
| Package | 12.5mm x 12.5mm SMD | 12.5mm x 12.5mm SMD | 12.2x12.2mm SMD | 12.5mm x 12.5mm SMD / 12.2x12.2mm SMD — Package size matches target.; MS127-330MT: Similar size, likely compatible footprint. |
The best alternative depends on your circuit's tolerance. MS127-330MT offers the same current and DCR in a similar package but with lower inductance (33µH). CYH125-100UH from the same family has a matching package but a lower current rating. Both require engineering review.
