A potential pin-compatible alternative from the same manufacturer with matching core specifications; review datasheet for full equivalency.
SPE1EM102G12OL is a 1000µF 25V solid aluminum electrolytic capacitor in a 10x12mm radial package. When searching for a substitute, prioritize matching the package size, capacitance, voltage, and temperature range.
Many candidates have different dimensions or mounting types.
Several candidates match or exceed key electrical ratings.
Not applicable for a passive component.
Direct replacement for SPE1EM102G12OL should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most promising path is SPT1EM102G12OR, which matches on all primary parameters. If unavailable, KNE51000UF25V149EC0026 is viable if 1mm extra height is acceptable.
The main risk is physical incompatibility. Several candidates have different package sizes or are surface-mount, which will not fit a through-hole design.
