Is there a pin-compatible replacement for SPZ1KM100E10O00RAXXX?

No pin-compatible replacement has been verified. While some candidates have a similar package, they are a different capacitor technology (standard vs. polymer) with critically different electrical characteristics like ESR and ripple current.

What risks should I check before replacing SPZ1KM100E10O00RAXXX?

Key risks include: 1) Electrical: Ensure the replacement can handle the application's ripple current and that its higher ESR won't affect circuit stability. 2) Package: Verify the physical dimensions (diameter, height, lead spacing) fit the PCB layout. 3) Thermal: A higher ESR will generate more heat.

AI replacement insight

Electrical riskhigh

Massive mismatch in ESR and ripple current due to technology difference (Polymer vs. Standard).

Package riskmedium

Candidates have different physical dimensions (height, diameter) requiring layout verification.

Sourcing risklow

Both polymer and standard capacitors are widely available from multiple vendors.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates are standard electrolytic types with significantly lower performance.

Best replacement path

Search for another 10µF 100V Polymer Aluminum capacitor in a similar radial package (6.3mm diameter).

Main risk

The primary risk is substituting a high-performance polymer capacitor with a standard electrolytic, leading to much higher ESR and lower ripple current handling, which can cause circuit failure or overheating.

Recommended alternatives

Higher voltage alternative with longer life, but is a standard type with lower performance and taller package.

Questions & answers

The best alternative would be another 10µF, 100V polymer aluminum capacitor with similar low ESR (≈50mΩ), high ripple current (≈1.5A), and a 6.3mm diameter radial package. Standard electrolytic capacitors are not suitable for high-performance applications.
