Is there a pin-compatible replacement for RST100UF10V002?

No pin-compatible, drop-in replacement has been confirmed. VZT101M1CTR-0506 is the closest, with a matching footprint but a minor height difference. Other functional alternatives require a different PCB layout.

What risks should I check before replacing RST100UF10V002?

The main risk is the package size. Before replacing, you must verify the physical dimensions. For VZT101M1CTR-0506, check the height clearance. For other options like the KNSCHA XT series, a PCB redesign is necessary.

RST100UF10V002 Alternatives, Datasheet & Cross Reference | KNSCHA

Finding a substitute for the KNSCHA RST100UF10V002, a 100uF 10V capacitor, requires careful attention to its compact 5x5.4mm SMD package. While several electrical upgrades exist, matching the physical form factor is the primary challenge.

AI replacement insight

Package riskmedium

No exact package match found. Alternatives are either slightly taller or require a full redesign.

Electrical risklow

All recommended alternatives meet or exceed the target's key electrical ratings like voltage and capacitance.

Can it be replaced directly?

No exact drop-in replacement has been identified. The closest alternative is VZT101M1CTR-0506, which matches the 5mm diameter but is slightly taller. All other candidates require a PCB layout change.

Best replacement path

VZT101M1CTR-0506 is the strongest candidate, offering a voltage upgrade in a nearly identical package. The main verification step is to confirm the 0.4mm height increase is acceptable.

Main risk

The primary risk is physical incompatibility. Most alternatives are in larger packages, and even the closest match has a slight height difference that requires verification.

Recommended alternatives

A strong functional alternative with a higher voltage rating and very similar package; verify height.
