A potential alternative with lower capacitance (1000µF) but higher voltage (100V). Requires engineering review.
Reviewing alternatives for the Ymin LKMI2501J152MF, a 1500µF 63V aluminum electrolytic capacitor. No direct replacements were found; available substitutes have lower capacitance, requiring careful engineering review.
Lower capacitance may increase ripple or affect stability.
All are radial cans, but dimensions vary and must be checked.
No, a direct 1-to-1 replacement for the LKMI2501J152MF was not found. All potential alternatives have a lower capacitance value of 1000µF instead of 1500µF.
Use a 1000µF capacitor with equal or higher voltage, but only after validating the impact on circuit performance, such as ripple voltage and hold-up time.
The primary risk is the 33% reduction in capacitance, which can negatively affect power supply filtering, stability, and transient response.
