Murata Electronics
Same series part with slightly lower inductance (3.6nH) but matching current and DCR ratings.
Murata's LQG15HS3N9B02D is a 3.9nH high-frequency chip inductor in a 0402 package, ideal for RF circuits. While no direct drop-in replacements exist, several parametric alternatives with different inductance values are available for consideration.
Inductance deviation in all candidates requires circuit re-evaluation or testing.
All suggested alternatives use the same 0402 package, ensuring physical compatibility.
Alternatives are available from the original manufacturer (Murata) and other vendors.
No direct drop-in replacement was found. All candidates have different inductance values, which is a critical parameter for RF circuits.
Use LQG15HS3N6B02D, which has the closest inductance (3.6nH) from the same Murata series.
The primary risk is inductance mismatch, which can detune RF filters, matching networks, or oscillators, affecting circuit performance.

| Inductance | 3.9 nH | 3.6 nH | 3.3 nH | 4.3 nH | 3.6 nH / 3.3 nH / 4.3 nH — Slightly lower than target. Verify circuit tolerance.; LQG15HH3N3B02D: Significantly lower inductance. Requires circuit validation.; LQG15HS4N3B02D: Higher inductance. Verify circuit tolerance.; VHF100505HQ3N3ST: Significantly lower inductance. Requires circuit validation. |
| Current | 750 mA | 750 mA | 800 mA | 750 mA | 750 mA / 800 mA — Rated current matches.; LQG15HH3N3B02D: Higher current rating is a safe upgrade.; LQG15HS4N3B02D: Rated current matches.; VHF100505HQ3N3ST: Higher current rating is a safe upgrade. |
| Dcr | 0.14 Ω | 0.14 Ω | - | 0.16 Ω | 0.14 Ω / 0.16 Ω / 0.13 Ω — DC resistance matches.; LQG15HS4N3B02D: Slightly higher DCR.; VHF100505HQ3N3ST: Lower DCR is an improvement. |
| Application | Commercial | - | AEC-Q200 | - | AEC-Q200 — Automotive grade offers higher reliability. |
The best alternative is likely LQG15HS3N6B02D. It is from the same Murata series and has the closest inductance value (3.6nH vs 3.9nH), but you must verify if this change is acceptable for your application.
