Functional alternative with matching inductance but in a larger package, offering higher current ratings.
Best Alternatives to FXL0518-4R7-M
The FXL0518-4R7-M is a 4.7µH SMD power inductor in a 5.4x5.2mm package, rated for 3.0A. While no direct drop-in replacements have been identified, several functional alternatives with higher current ratings are available in larger packages.
AI replacement insight
Package riskhigh
All functional alternatives are in larger packages and require a board redesign.
Electrical risklow
Alternatives offer superior current handling and lower DCR.
Can it be replaced directly?
No, a direct, drop-in replacement for the FXL0518-4R7-M was not found. All candidates with matching inductance have different physical packages.
Best replacement path
For new designs, consider the FXL series in larger packages (e.g., FXL0650-4R7-M) for improved current handling. For existing boards, a replacement with the same 5.4x5.2mm footprint is required.
Main risk
Package mismatch is the main risk; no identified alternatives will fit the existing PCB layout.
