Is there a pin-compatible replacement for AC0603FR-077K5L?

Several 0603 package resistors are pin-compatible in form factor, such as Yageo's RC series. However, they are not functional drop-ins as they are general-purpose parts, not automotive-grade, and may have different resistance values.

What risks should I check before replacing AC0603FR-077K5L?

The main risk is substituting a general-purpose resistor for an automotive-grade (AEC-Q200) part, which can affect reliability in harsh environments. Also, verify that any resistance difference is acceptable for your circuit's performance.
