Murata Electronics
A functional alternative with matching inductance and better electricals, but in a smaller 0402 package.
Finding a substitute for the Murata LQG18HN33NJ00D 33nH inductor involves checking package size and key electrical parameters. Alternatives exist but may require design adjustments for package or inductance differences.
Some alternatives are in a different package (0402 vs 0603), requiring a PCB redesign.
Some same-package alternatives have different inductance, which can impact RF circuit performance.
No direct drop-in replacement was identified. All viable candidates have critical differences in either package size or inductance value.
A functional alternative with board redesign (e.g., LQW15AN33NG80D) or a parametric alternative with circuit re-evaluation (e.g., LQW18AN39NG80D).
The primary risks are physical incompatibility due to different package sizes and functional changes from mismatched inductance values.

| Feature / factor | LQG18HN33NJ00D | LQW15AN33NG80D | LQW18AN39NG80D | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0603 (1608 metric) | 0402 (1005 metric) | 0603 (1608 metric) | 0402 (1005 metric) / 0603 (1608 metric) — Smaller package requires PCB layout change.; LQW18AN39NG80D: Package size matches. | |
| Inductance | 33 nH | 33 nH | 39 nH | 33 nH / 39 nH — Inductance value matches.; LQW18AN39NG80D: Inductance is higher, may affect circuit tuning. | |
| Current | 0.45 A | 0.62 A | 1.0 A | 0.62 A / 1.0 A — Higher current rating provides more margin.; LQW18AN39NG80D: Higher current rating provides more margin. | |
| Dcr | 0.6 Ω | 0.336 Ω | 0.16 Ω | 0.336 Ω / 0.16 Ω — Lower DCR improves efficiency.; LQW18AN39NG80D: Lower DCR improves efficiency. | |
| Q Factor | 12 min | - | 40 min | 40 min — Higher Q factor indicates lower loss. |
LQW15AN33NG80D offers matching inductance and better electricals but in a smaller 0402 package, requiring a board change. For the same 0603 package, options have different inductance values and must be carefully evaluated.
