A potential pin-compatible alternative with matching capacitance, voltage, and package size.
Find alternatives for the EWH1AM221D11OT, a 220µF 10V radial aluminum electrolytic capacitor. This page lists potential pin-compatible replacements and functional alternatives with different packages for design flexibility.
Multiple candidates are SMD and not physically compatible with the through-hole target.
For pin-compatible options, secondary parameters like ESR, ripple current, and lifetime must be verified to ensure circuit stability and reliability.
Multiple manufacturers offer parts with similar specifications, providing sourcing flexibility.
Direct replacement for EWH1AM221D11OT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement path depends on your manufacturing capabilities. For a direct, drop-in replacement, consider KM227M010D11RR0VH2FP0 or GR227M010D11RR0VH4FP0 after verifying their datasheets. If a PCB redesign is feasible, SMD alternatives offer higher voltage ratings.
The main risk is package incompatibility. Several functional alternatives are Surface Mount (SMD) and cannot replace the through-hole Radial target without a board redesign.
