UCS2C820MHD Equivalent & Substitute Parts

Part Overview

The UCS2C820MHD is an 82 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is rated for general purpose applications with a 10,000 hour lifetime at 105°C and operates across the temperature range of -40°C to 105°C. The part is currently active in production status with ROHS3 compliance.

Substitute parts are identified when equivalent capacitance and tolerance values are maintained while voltage ratings and operational characteristics remain within acceptable parameters for the application circuit.

Substitute Part Grouping Explanation

Substitution for the UCS2C820MHD is determined by the following criteria:

Capacitance value must remain 82 µF
Tolerance must be ±20%
Voltage rating must be equal to or greater than 160 V
Physical dimensions (diameter, height, lead spacing) must match for PCB compatibility
Mounting type must be Through Hole, Radial configuration
Operating temperature range must encompass -40°C to 105°C

Two substitute parts meet these criteria with voltage ratings upgraded to 200 V, providing enhanced voltage margin while maintaining identical physical form factor and electrical specifications for capacitance and tolerance.
