AISHI
A 330µF 100V capacitor with longer life, but requires PCB redesign due to a larger diameter and different lead spacing.
Finding a substitute for the AISHI ERE1KM331W25OT, a 330µF 100V radial capacitor, requires careful matching of its 12.5mm x 25mm package and 5.0mm lead spacing. While functional alternatives exist, physical compatibility is the primary challenge.
Candidates have different diameters and lead spacing, preventing a drop-in fit.
Key electrical parameters like capacitance and voltage are matched by some candidates.
No direct drop-in replacement has been identified. All reviewed candidates have physical package differences that prevent direct substitution.
Search for a 330µF, 100V, 105°C radial capacitor specifically with a 12.5mm diameter and 5.0mm lead spacing.
The primary risk is physical incompatibility. Many functional alternatives use different case sizes or lead spacing, requiring PCB redesign.
