Is there a pin-compatible replacement for EEEFK1C221P?

Yes, EEEFTE221XAP is a pin-compatible replacement for EEEFK1C221P. It shares the same 'D8' package (6.3mm x 7.7mm) and pin configuration, allowing for a direct drop-in replacement on the PCB.

What risks should I check before replacing EEEFK1C221P?

Before replacing EEEFK1C221P, verify the substitute's package dimensions, voltage rating (must be ≥16V), ripple current rating (≥280mA), and ESR (≤0.34Ω). For non-pin-compatible parts, you must confirm the PCB layout can be adapted.
