AI replacement insight
Package riskhigh
All candidates are in smaller packages, requiring a board redesign.
Electrical riskmedium
Candidates have wider tolerance (±20% vs ±10%) and target's saturation current is unknown.
Sourcing risklow
Candidates are active parts from a major manufacturer.
Can it be replaced directly?
No direct, drop-in replacement has been identified. All reviewed candidates have a different package footprint.
Best replacement path
Modernization to a smaller, higher-performance inductor like the Sunlord WPN series, which requires a PCB redesign.
Main risk
Package incompatibility is the primary risk, mandating a PCB layout modification.
