Is there a pin-compatible replacement for FRC0603J515 TS?

Yes, many 0603 chip resistors are physically pin-compatible. However, no electrically identical drop-in replacement has been found. The suggested alternatives, like FRC0603J475 TS, match the package but have different resistance values that require engineering review.

What risks should I check before replacing FRC0603J515 TS?

The primary risk is the change in resistance. The target is 5.1MΩ, while alternatives are 4.7MΩ or 5.6MΩ. This deviation can affect the performance of analog circuits, such as changing filter cutoff frequencies, amplifier gain, or voltage divider ratios. It is crucial to analyze or test the impact on your specific application.
