A pin-compatible MLCC with identical ratings and a tighter 5% tolerance.
Find suitable replacements for the AVX 0603YC105KAT2A, a 1uF 16V 10% X7R MLCC in an 0603 package. This guide reviews pin-compatible upgrades to help you manage your bill of materials.
Upgrades to tighter tolerance or higher voltage are generally safe.
Alternatives exist in different packages (1206, 1210) which are not drop-in replacements.
This is a very common capacitor value and size with multiple sources.
Yes, 0603YC105JAT2A is a direct replacement with a better tolerance (5% vs 10%), and 06033C105KAT2A is a direct replacement with a higher voltage rating (25V vs 16V).
Upgrade to a pin-compatible MLCC with tighter tolerance (0603YC105JAT2A) or higher voltage (06033C105KAT2A).
The main risk is selecting a part with a different package size or capacitor technology (e.g., Tantalum instead of Ceramic), which would require a board redesign.

| Feature / factor | 0603YC105KAT2A | 06033C105KAT2A | 0603YC105JAT2A | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0603 (1608 metric) | 0603 (1608 metric) | 0603 (1608 metric) | 0603 (1608 metric) — Identical package and pin count.; 0603YC105JAT2A: Identical package and pin count. | |
| Capacitance | 1uF | 1uF | 1uF | 1uF — Capacitance matches.; 0603YC105JAT2A: Capacitance matches. | |
| Voltage | 16V | 25V | 16V | 25V / 16V — Higher voltage rating provides more margin.; 0603YC105JAT2A: Voltage rating matches. | |
| Tolerance | 10% | 10% | 5% | 10% / 5% — Tolerance matches.; 0603YC105JAT2A: Tighter tolerance is a safe upgrade. | |
| Dielectric | X7R | X7R | X7R | X7R — Dielectric material matches.; 0603YC105JAT2A: Dielectric material matches. |
The best alternative is 0603YC105JAT2A, which offers a tighter 5% tolerance. Another strong option is 06033C105KAT2A with a higher 25V rating. Both are pin-compatible upgrades.
