KNSCHA
Pin-compatible form factor and key electricals, but has a shorter operational lifetime.
Find substitutes for the AISHI ERZ1VM221F12OT, a 220µF 35V radial aluminum electrolytic capacitor. Alternatives include a pin-compatible option with a different lifetime and functional alternates requiring board changes.
Most alternatives are SMD and not physically compatible with the through-hole target.
The only pin-compatible option has a lower lifetime rating, which could impact reliability.
Direct replacement for ERZ1VM221F12OT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
For a drop-in replacement, KNSCHA 01EC1085 matches the package and key specs but has a shorter lifetime. For new designs, consider SMD functional alternates.
The primary risk is package mismatch. Most alternatives are Surface Mount (SMD) and require a board redesign. The pin-compatible option has a shorter lifetime.
