UHD1V151MPD Equivalent & Substitute Parts

Part Overview

The UHD1V151MPD is a 150 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as Not For New Designs, indicating it has reached end-of-life status. The UHD series offers a 3000-hour lifetime rating at 105°C with general-purpose applications.
