AISHI
Potential pin-compatible alternative with identical package and key electricals; series difference requires review.
Find substitutes for the AISHI ERJ1EM101D12OT, a 100µF 25V radial aluminum electrolytic capacitor. This guide reviews potentially pin-compatible options and functional alternatives requiring design changes.
Many alternatives are SMD and require a board redesign.
Most alternatives have a significantly lower lifetime rating than the target's 8000 hours.
Direct replacement for ERJ1EM101D12OT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with Datasheet verified or Strong match candidates for ERJ1EM101D12OT, then review parametric alternatives for package and electrical fit.
The main risks are physical incompatibility (package size or type) and reduced operational lifetime with most alternatives.
