ECO-S2DA471DA Equivalent & Substitute Parts

Part Overview

The ECO-S2DA471DA is a 470 µF, 200 V aluminum electrolytic capacitor in radial, can snap-in package manufactured by Panasonic Electronic Components. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. The part operates across a temperature range of -40°C to 105°C with a 3000-hour lifetime rating at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical compatibility:

Direct Equivalents (Same Voltage Rating - 200V): Direct substitutes maintain the original 200 V voltage specification and are mechanically and electrically interchangeable with the ECO-S2DA471DA. These parts share identical capacitance (470 µF), tolerance (±20%), lead spacing (10.00 mm), case diameter (30.00 mm), and mounting configuration (through-hole, snap-in). Variations in ESR and ripple current ratings remain within acceptable operational parameters for general-purpose applications.

Upgrade Options (Higher Voltage Rating - 250V): Upgrade substitutes provide 250 V voltage rating while maintaining all other critical parameters: 470 µF capacitance, ±20% tolerance, 10.00 mm lead spacing, 30.00 mm case diameter, and through-hole snap-in mounting. These parts are suitable for applications where higher voltage margin is beneficial, though they are not required for 200 V circuit operation.
