Needs validationlow risk
A clear upgrade from the same manufacturer with identical inductance, 3x current rating, and lower DCR.
Best Alternatives to VHF100505H2N2ST
VHF100505H2N2ST is a 2.2nH, 300mA high-frequency inductor in a 0402 package. Several alternatives exist, including direct upgrades with higher current handling, but careful review of electrical parameters for your specific application is required.
AI replacement insight
Electrical riskmedium
Inductance values vary, and unknown saturation current requires validation.
Package risklow
All recommended alternatives are in the same 0402 package.
Sourcing risklow
Alternatives are available from major manufacturers like TDK and Sunlord.
Can it be replaced directly?
No guaranteed drop-in replacement exists without circuit validation. However, VHF100505HQ2N2ST is a very strong candidate that offers significant performance improvements and is likely to work.
Best replacement path
VHF100505HQ2N2ST from the same manufacturer is the most direct upgrade path, offering superior current and DCR with identical inductance.
Main risk
The primary risk is the unknown saturation current (Isat) for all candidates, which could affect inductor performance under DC bias or high current peaks.
