Is there a pin-compatible replacement for R08B1B102KN0B0S0N0?

No pin-compatible replacement has been confirmed. The target part's lead pitch is not specified, so any alternative requires physical verification to ensure it fits the PCB layout.

What risks should I check before replacing R08B1B102KN0B0S0N0?

Key risks include: 1) Voltage rating must be ≥2kV. 2) Tolerance should be ±10% or tighter. 3) Temperature characteristic (dielectric) should be Y5P or better. 4) Physical dimensions like lead pitch must match your board.

R08B1B102KN0B0S0N0 Alternatives, Datasheet & Cross Reference | STE

Finding a substitute for the STE R08B1B102KN0B0S0N0, a 1nF 2kV Y5P ceramic capacitor, requires careful matching of electrical and physical parameters. Alternatives often involve trade-offs in tolerance or temperature stability.

AI replacement insight

Electrical riskhigh

Using a part with a less stable dielectric (Y5U/Y5V) or wider tolerance can impact circuit timing or filtering performance.

Package riskmedium

Lead pitch and disc diameter must be verified to ensure fit on the PCB, as this data is missing for the target.

Can it be replaced directly?

No direct drop-in replacement was found. U12E1D102MN0B0S0N0 is a potential functional alternative but requires engineering review due to its wider tolerance and less stable temperature characteristic.

Best replacement path

Find a capacitor with 1nF capacitance, ≥2kV voltage, ≤±10% tolerance, a Y5P or better tempco (e.g., C0G/NP0), and matching physical dimensions.

Main risk

The main risks are circuit malfunction from a part with wider tolerance or a less stable temperature characteristic (Y5U/Y5V vs Y5P).

Recommended alternatives

A 1nF capacitor with higher voltage but wider tolerance and a less stable temperature characteristic.
