No direct pin-compatible replacement is proven among these candidates.
Use the exact 120pF part; consider 150pF only if the circuit allows +25% capacitance.
Capacitance mismatch can change filter, timing, or RF behavior.

| Feature / factor | CC0603JRNPO9BN121 | CC0603JRNPO9BN151 | CC0603JRNPO9BN820 | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0603 | 0603 | - | 0603 — same case | |
| Pinout | 2 term | 2 term | - | 2 term — nonpolar MLCC | |
| Voltage | 50V | 50V | - | 50V — no voltage gain | |
| Tolerance | ±5% | ±5% | - | ±5% — same tol | |
