FEXL0420A-1R5M is a 1.5µH, 7.6A power inductor in a 4.1x4.1mm SMD package. While no direct pin-compatible replacements are identified, several functional alternatives with different package sizes are available.

AI replacement insight

Package riskhigh

No candidates match the target's 4.1x4.1mm package, requiring a mandatory PCB redesign.

Electrical risklow

Several candidates offer equivalent or superior current ratings and DCR, but must be evaluated for the specific circuit.

Sourcing riskmedium

All candidates are from the same manufacturer, which may not improve supply chain diversity. Check distributor stock.

Can it be replaced directly?

No direct, pin-compatible replacement for FEXL0420A-1R5M is available. All alternatives require a board redesign due to different package sizes.

Best replacement path

Redesigning the PCB for a larger but electrically superior part like FEXL0630A-1R5M or FXL1040-1R5-M.

Main risk

Physical incompatibility. The primary challenge is finding a part that fits the existing 4.1x4.1mm PCB footprint.
