Is there a pin-compatible replacement for TAJA335K016RNJ?

TAJA225K025RNJ shares the same 1206 package and pinout, but its lower capacitance (2.2µF vs 3.3µF) makes it a parametric, not a direct, replacement. Circuit testing is essential.

What risks should I check before replacing TAJA335K016RNJ?

Key risks include package mismatch, which requires a new PCB layout, and capacitance differences, which can affect circuit timing or stability. Also verify voltage rating and ESR are sufficient.
