AISHI
A strong alternative with matching key electricals, package, and a longer lifetime rating.
Finding a substitute for the KNSCHA SHG330UF100V146EC0462 330µF 100V capacitor requires matching electrical specs and the 16x20mm radial package. Several alternatives exist with varying degrees of compatibility.
Many alternatives have different dimensions or mounting types (e.g., snap-in).
Key parameters (330µF, 100V) are common, but secondary specs like ESR and lifetime can vary.
Yes, the AISHI ERF1KM331L20OT is a potential pin-to-pin replacement, but secondary parameters like ESR should be verified from the datasheet.
The AISHI ERF1KM331L20OT is the best candidate, offering identical key parameters and package size, plus an improved lifetime.
The main risk when substituting this capacitor is package incompatibility. Many alternatives have different can sizes or mounting styles that will not fit the original PCB layout.
