SPZ1HM331G15O00RAXXX
AISHI
Needs validationmedium risk
Radial mount alternative with much higher voltage, but is significantly larger and requires physical fit verification.
Best Alternatives to SPT1CM331E09OR
Finding a substitute for the Yunxing SPT1CM331E09OR, a 330µF 16V radial capacitor, requires careful attention to physical dimensions. While several parts match electrically, they differ in package size or mounting style, necessitating engineering review before replacement.
AI replacement insight
Package riskhigh
All candidates have a different package size or mounting style (SMD vs. Radial).
Electrical risklow
All candidates match key electricals (capacitance, tolerance) and offer a safer, higher voltage rating.
Can it be replaced directly?
No direct drop-in replacement has been identified. All candidates have significant physical differences from the original part, requiring engineering review.
Best replacement path
Check board clearance for radial parts like SPZ1VM331G12O00RAXXX. If space is unavailable, a board redesign for an SMD equivalent is necessary.
Main risk
The primary risk is mechanical incompatibility. The target is a compact radial capacitor, and alternatives are either a different mounting type (SMD) or a much larger radial package.
