Likely footprint compatible with better current ratings, but has a narrower operating temperature range.
Finding a substitute for the Sunltech SLO0520H1R0MTT 1.0µH power inductor involves balancing physical fit and electrical specifications. While several functional alternatives exist, key trade-offs include package size and operating temperature range.
Most alternatives have different footprints, requiring PCB redesign. Only one candidate is closely matched.
Many alternatives have a lower max operating temperature. Higher DCR in some parts can reduce efficiency.
No direct drop-in replacement has been identified that matches all key parameters. MWSA0518S-1R0MT is footprint-compatible but has a lower temperature rating, requiring engineering review.
For form-fit, MWSA0518S-1R0MT is the closest but requires checking the lower +125°C temp limit. For an electrical upgrade where space is not a constraint, SLO0630H1R0MTT offers superior performance.
The primary risks when replacing SLO0520H1R0MTT are package size mismatches and finding an alternative that matches its wide -55°C to +150°C operating temperature range.

| Feature / factor | SLO0520H1R0MTT | MWSA0518S-1R0MT | SLO0630H1R0MTT | MWSA0603S-1R0MT | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 5.7x5.2x2.0mm | 5.4x5.2x1.8mm | 7.1x6.6x3.0mm | 6.6x7.0x3.0mm | 5.4x5.2x1.8mm / 7.1x6.6x3.0mm / 6.6x7.0x3.0mm — Footprint is highly compatible with target's 5.7x5.2x2.0mm.; SLO0630H1R0MTT: Physically larger, requires layout change.; MWSA0603S-1R0MT: Physically larger, requires layout change. |
| Temperature | -55°C to +150°C | -40°C to +125°C | -55°C to +150°C | -40°C to +125°C | -40°C to +125°C / -55°C to +150°C — Candidate has a narrower operating temperature range.; SLO0630H1R0MTT: Operating temperature range matches.; MWSA0603S-1R0MT: Candidate has a narrower operating temperature range. |
| Current | 8.0 A | 9.0 A | 22.0 A | 15.0 A | 9.0 A / 22.0 A / 15.0 A — Saturation current (Isat) is higher.; SLO0630H1R0MTT: Saturation current (Isat) is significantly higher.; MWSA0603S-1R0MT: Saturation current (Isat) is higher. |
| Resistance | 15 mΩ | 17 mΩ | 6.8 mΩ | 7.4 mΩ | 17 mΩ / 6.8 mΩ / 7.4 mΩ — DC Resistance is slightly higher, may increase losses.; SLO0630H1R0MTT: DC Resistance is much lower, reducing losses.; MWSA0603S-1R0MT: DC Resistance is lower. |
The best alternative depends on your priority. For physical compatibility, MWSA0518S-1R0MT is the closest match but has a lower temperature rating. For the best electrical performance, SLO0630H1R0MTT is a strong upgrade but is physically larger.
