Is there a pin-compatible replacement for R06B1B271KN0B0S0N0?

No, a direct pin-compatible replacement with identical specifications was not found. R06B1B221KN0B0S0N0 is pin-compatible in form factor but has a lower capacitance of 220pF versus the original 270pF.

What risks should I check before replacing R06B1B271KN0B0S0N0?

The primary risks are package mismatch (through-hole vs. surface-mount), which requires a board redesign, and changes in capacitance or dielectric type (e.g., Y5P vs. X7R), which can affect filtering, timing, and stability.
