Is there a pin-compatible replacement for TAJA334K035RNJ?

Yes, parts like TAJA224K035RNJ and TAJA474K035RNJ are pin-compatible as they share the same 1206 package and 2-pin layout. However, their electrical parameters like capacitance differ, so they are not drop-in replacements without engineering review.

What risks should I check before replacing TAJA334K035RNJ?

The main risk is the change in capacitance, which can affect filter corner frequencies, timing circuits, or loop stability in power supplies. Also, check for differences in Equivalent Series Resistance (ESR), as this impacts ripple and efficiency.
