Is there a pin-compatible replacement for N06B1B331KN0B0S0N0?

While several parts share the same 2-pin 'Disc' package, none are electrically identical. The key difference is the capacitance value. Therefore, no pin-to-pin functional equivalent was identified.

What risks should I check before replacing N06B1B331KN0B0S0N0?

The main risk is the change in capacitance. A lower or higher value can affect filter corner frequencies, timing circuits, or circuit stability. You must verify if your application can tolerate a -18% or +42% change in capacitance.

N06B1B331KN0B0S0N0 Alternatives, Datasheet & Cross Reference | STE

N06B1B331KN0B0S0N0 is a 330pF, 1kV high-voltage ceramic disc capacitor from STE. Finding a direct replacement is challenging, as available alternatives have different capacitance values that require careful engineering review.

AI replacement insight

Electrical riskhigh

Capacitance values differ by -18% to +42%, which is likely to impact circuit function.

Package risklow

All candidates share the same 'Disc' package and pin count, but physical dimensions should be verified from datasheets.

Can it be replaced directly?

No direct, drop-in replacement was found. All alternatives have different capacitance values and require engineering review.

Best replacement path

Test candidates in-circuit. If the circuit is for bulk decoupling, a higher capacitance like 470pF may be acceptable. If used in a timing or filter circuit, a closer value is needed.

Main risk

The primary risk is the capacitance mismatch, which can alter circuit behavior such as filter characteristics or oscillator frequency.

Recommended alternatives

A form-fit alternate with lower capacitance (270pF vs 330pF) but a higher voltage rating (2kV vs 1kV).
