Lelon
A functional alternate with upgraded voltage and ESR in a larger surface-mount (SMD) package.
Finding a replacement for the NJCON 2210350812R00, a 220µF 35V polymer aluminum capacitor, involves choosing between form-fit parts with lower performance or electrically similar parts that require a board redesign.
Using a standard electrolytic substitute will drastically increase ESR and lower ripple current handling.
Using an electrically comparable part requires changing from a through-hole to a surface-mount layout.
Many alternatives exist across different performance tiers and package types.
No direct drop-in replacement has been identified that matches both the through-hole package and the high-performance electrical characteristics (low ESR, high ripple current) of the original polymer capacitor.
Redesign for an SMD polymer capacitor like the Lelon VZH series for performance, or accept a performance downgrade with a radial electrolytic like the AISHI ERJ series.
A mismatch in either package (form/fit) or key performance parameters (ESR, ripple current) is unavoidable with currently identified alternatives.

The best alternative depends on your priority. For similar electrical performance (low ESR, high ripple), Lelon's VZH221M1VTR-0810L is a strong functional alternate but requires changing from through-hole to a surface-mount design. If maintaining the radial package is critical, AISHI's ERJ1VM221F12OT is a form-fit match but has significantly lower performance.
