Upgrade with higher 25V rating and tighter ±10% tolerance from the same manufacturer.
TCC0603X5R225M160CT is a 2.2µF, 16V, ±20% X5R ceramic capacitor in a 0603 package. Numerous pin-compatible and upgrade alternatives are available from multiple manufacturers, often with improved voltage and tolerance ratings.
All candidates meet or exceed voltage and tolerance specs. DC bias effect is the main point to verify.
All candidates use the standard 0603 package, ensuring physical compatibility.
Multiple active alternatives are available from various manufacturers, ensuring a stable supply chain.
Yes, several direct and upgrade replacements are available. C1608X5R1C225KT000N from TDK is a strong pin-compatible option with tighter tolerance.
Use an upgrade path candidate like TCC0603X5R225K250CT, which offers a higher voltage rating (25V) and tighter tolerance (±10%) from the same manufacturer.
The primary risk when substituting MLCCs is a potential difference in capacitance change under DC bias voltage, which varies by manufacturer and part series.

Upgrade with higher 25V rating and tighter ±10% tolerance from the same manufacturer.
