ALC70D472CB063 Equivalent & Substitute Parts

Part Overview

The ALC70D472CB063 is a 4700 µF, 63 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by KEMET. This component is classified as Active product status and is designed for general-purpose applications requiring high capacitance energy storage in through-hole mounting configurations. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 13000 hours at 85°C.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications.
