A form-fit match with higher current ratings, but a narrower operating temperature range.
Finding a substitute for the SFE3015A-100M-F-HF 10µH inductor requires careful review of electrical parameters. While several parts share the 3030 package, key differences in current ratings, resistance, and temperature range exist.
Several candidates match the 3x3mm footprint.
Candidates have weaker temperature range, higher DCR, or lower saturation current.
No direct drop-in replacement has been identified. All form-fit candidates have significant electrical trade-offs requiring engineering review.
TDK's VLS3012CX-100M-1 is a strong candidate if the application's maximum operating temperature is below 105°C.
Electrical parameter mismatch, particularly saturation current, DC resistance, and operating temperature range.

| Feature / factor | SFE3015A-100M-F-HF | VLS3012CX-100M-1 | LVS303012H-100M-N | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 3030 (Metric 3030) | 3030 (1212 Metric) | 3030 | 3030 (1212 Metric) — Package size 3.0x3.0x1.2mm matches target footprint.; LVS303012H-100M-N: Package size 3.0x3.0mm matches target footprint. | |
| Saturation Current A | 0.92A | 1.0A | 0.72A | 1.0A / 0.72A — Higher saturation current provides more margin.; LVS303012H-100M-N: Lower saturation current poses a critical risk of failure. | |
| Current A | 0.8A | 1.0A | 1.0A | 1.0A — Higher RMS current rating.; LVS303012H-100M-N: Higher RMS current rating. | |
| Dcr Ohm | 0.27Ω | 0.324Ω | 0.27Ω | 0.324Ω / 0.27Ω — Slightly higher DCR may reduce efficiency.; LVS303012H-100M-N: Matches typical DCR for similar efficiency. | |
| Temperature | -40 to +125°C | -40 to +105°C | -40°C to 125°C | -40 to +105°C / -40°C to 125°C — Narrower temperature range is a key limitation.; LVS303012H-100M-N: Matches operating temperature range. |
TDK's VLS3012CX-100M-1 is a strong candidate with a matching package and higher current ratings, but its lower maximum temperature of 105°C must be acceptable for your application.
