A 100µF 25V capacitor from the same manufacturer in an identical package, representing a direct upgrade path.
The Panasonic EEEFK1C101P is a 100µF 16V surface-mount aluminum electrolytic capacitor in a 6.3x5.8mm package, valued for its low impedance. Replacing it requires matching capacitance and tolerance, ensuring the voltage is equal or higher, and verifying physical and secondary electrical compatibility.
Some candidates are taller and may not fit.
ESR and ripple current must be verified.
This is a common capacitor value and size.
Yes, several parts like EEEFK1E101SP and EFVR035ADA101M0658 are available in the same package, but require review of secondary parameters like ESR.
Upgrade to Panasonic's EEEFK1E101SP for a higher voltage rating in an identical package from the same manufacturer family.
The main risk is physical incompatibility from candidates with different package heights, and electrical mismatch in ESR or ripple current.
