KNSCHA
A potential pin-to-pin replacement from the same manufacturer with identical key specs and improved ripple current.
Find pin-compatible and functional alternatives for the KNSCHA RSL220UF25V021, a 220uF 25V aluminum electrolytic capacitor. This guide provides verified substitutes, including upgrades and cross-vendor options.
The 6.3x7.7mm SMD package is standard, and multiple candidates match the form factor.
ESR and ripple current are critical. A low-ESR part used in a general-purpose circuit can cause issues.
This is a common capacitor value with many available cross-vendor options.
Direct replacement for RSL220UF25V021 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The safest path is using KNSCHA VT220UF25V167RV160, which has identical primary specs and is from the same manufacturer.
The main risk when substituting is a mismatch in Equivalent Series Resistance (ESR), which can impact circuit stability.
