These parts maintain identical electrical specifications (330 µF, 10 V, ±20% tolerance, 2000 Hrs @ 105°C) and mechanical dimensions (8.00 mm diameter, 10.50 mm height, 8.30 mm x 8.30 mm land size). All four variants carry AEC-Q200 automotive qualification ratings and are designated as halogen-free where specified. These parts are suitable for applications requiring automotive-grade reliability and high-temperature reflow capability.

Parametric Equivalent (Nichicon UUX Series): The part UUX1A331MNL6GS is a parametric equivalent manufactured by Nichicon. It matches all core electrical parameters (330 µF, 10 V, ±20% tolerance, 2000 Hrs @ 105°C) and mechanical dimensions identical to the main part. This part is classified as general purpose and does not carry automotive ratings.

Substitution eligibility is determined by:
