An electrical upgrade with superior current ratings and lower DCR, but in a much larger package.
Best Alternatives to ANR6045T470M
ANR6045T470M is a 47µH power inductor in a 6.0x6.0mm package. While no direct pin-compatible replacements are available, several functional alternatives exist with superior electrical characteristics, but all require PCB redesign due to different package sizes.
AI replacement insight
Package riskhigh
All candidates have different footprints, requiring mandatory PCB redesign.
Electrical risklow
Most candidates offer superior current ratings. Some have higher DCR, which needs efficiency analysis.
Can it be replaced directly?
No direct, pin-compatible replacement for ANR6045T470M has been identified. All potential alternatives require a PCB layout change due to different package sizes.
Best replacement path
For an electrical upgrade where board space is available, parts like SDRI127-470MT offer significantly better current handling and efficiency. For applications needing automotive qualification, FAUL0630-470MT is a candidate.
Main risk
The primary risk is mechanical incompatibility. The package footprint of all candidates differs from the target's 6.0x6.0mm size, making them not drop-in compatible.
