Is there a pin-compatible replacement for FZ100UF35V90RV0145?

Yes, several candidates are potentially pin-compatible. VZT101M1HTR-0607 is a strong pin-compatible upgrade. RX100UF50V90RV0105 is also a likely pin-compatible upgrade, but you must verify its ESR and ripple current from the datasheet before use.

What risks should I check before replacing FZ100UF35V90RV0145?

Before replacing FZ100UF35V90RV0145, you must verify the substitute's ripple current rating and ESR (or impedance). A part with lower ripple current or higher ESR can overheat and fail. Also, confirm the package dimensions, especially height, are compatible with your PCB layout.
