Likely pin-compatible replacement from the same manufacturer with identical key electrical and physical parameters.
Reviewing substitutes for the Yunxing SPT1EM102G12OR, a 1000µF 25V solid aluminum capacitor. Key factors for replacement are matching the radial 10x12mm package, solid polymer technology for low ESR, and the -55°C to +105°C temperature range.
Many alternatives have different dimensions or mounting types, requiring board layout changes.
Ensure substitutes match solid polymer technology for low ESR, or verify performance if using standard electrolytic.
Multiple manufacturers produce capacitors with similar specifications.
Direct replacement for SPT1EM102G12OR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most direct path is SPE1EM102G12OL from the same manufacturer, which matches all critical parameters.
The primary risk when considering other alternatives is physical incompatibility due to different package sizes or mounting types (SMD vs. through-hole).
