Strong upgrade path with higher voltage (63V), longer life (10000h), and a very similar package size.
Find and compare replacements for the KM337M050G17RR0VH2FP0, a 330µF 50V radial aluminum electrolytic capacitor. This guide analyzes several alternatives, highlighting upgrades and potential form-fit-function substitutes.
Candidates have different heights. SMD parts were rejected. Verify board space.
Key specs match or are upgrades, but ESR and ripple current must be checked.
Multiple vendors offer parts with similar specifications, indicating good availability.
No verified direct drop-in replacement has been identified. However, several functional alternatives with similar or better parameters are available for review.
YMIN LKME1601J331MF is the best upgrade path, offering higher voltage (63V) and longer life in a nearly identical package.
The primary risks are physical package differences (size) and variations in secondary electrical parameters like ESR and ripple current.
