Sunlord
Same package and manufacturer, but with a slightly lower inductance of 3.0nH that requires engineering review.
Finding a replacement for the Sunlord SDCL0603Q3N3BT02B03 3.3nH inductor involves trade-offs. While some options match the 0201 package, they may have different inductance values. Others offer better electrical performance but require a board redesign due to a larger package.
Several candidates have different inductance values. Saturation current is unknown for all parts.
Many alternatives are in larger 0402 or 0603 packages and are not drop-in compatible.
Alternatives are available from the same and other major manufacturers.
No direct drop-in replacement has been verified. The closest candidate, SDCL0603Q3N0BT02B03, has a different inductance value and requires engineering review.
SDCL0603Q3N0BT02B03 is the closest option due to its matching 0201 package and ratings, but its slightly lower 3.0nH inductance must be evaluated.
The primary risks are package mismatch requiring a board redesign, or inductance deviation affecting circuit tuning and performance.

|---|---|---|---|---|---|
| Package | 0201 (0603 Metric) | 0201 (0603 Metric) | 0201 (0603 Metric) | 0603 (1608 Metric) | 0201 (0603 Metric) / 0603 (1608 Metric) / 0402 — Same package and pin count.; SDCL0603Q2N7BT02B03: Same package and pin count.; SDCL1608C3N3STDF: Much larger package requires board layout change.; VHF100505HQ3N3ST: Larger package requires board layout change. |
| Inductance | 3.3 nH | 3.0 nH | 2.7 nH | 3.3 nH | 3.0 nH / 2.7 nH / 3.3 nH — Slightly lower inductance.; SDCL0603Q2N7BT02B03: Inductance is outside typical tolerance.; SDCL1608C3N3STDF: Inductance matches.; VHF100505HQ3N3ST: Inductance matches. |
| Current | 450 mA | 450 mA | 500 mA | 500 mA | 450 mA / 500 mA / 800 mA — Rated current matches.; SDCL0603Q2N7BT02B03: Higher rated current.; SDCL1608C3N3STDF: Higher current rating.; VHF100505HQ3N3ST: Significantly higher current rating. |
| Dcr | 0.25 Ω | 0.25 Ω | 0.20 Ω | 0.15 Ω | 0.25 Ω / 0.20 Ω / 0.15 Ω / 0.13 Ω — DC resistance matches.; SDCL0603Q2N7BT02B03: Lower DC resistance is beneficial.; SDCL1608C3N3STDF: Lower DCR.; VHF100505HQ3N3ST: Significantly lower DCR. |
The best alternative is likely SDCL0603Q3N0BT02B03. It shares the same 0201 package, manufacturer, and key ratings, but has a slightly lower inductance of 3.0nH (vs 3.3nH) which must be verified for your application.
