Is there a pin-compatible replacement for SN74LVC1G86DCKR?

Yes, SN74AHC1G86DCKR shares the same SC-70-5 package and pinout. While mechanically compatible, its electrical characteristics like minimum voltage and output current differ, so it is not a direct drop-in replacement for all circuits.

What risks should I check before replacing SN74LVC1G86DCKR?

When considering a replacement, verify the minimum supply voltage (VCC), required output drive current, and maximum propagation delay. The SN74AHC1G86DCKR, for example, requires a higher minimum voltage (2V vs 1.65V) and has a weaker output.
