Is there a pin-compatible replacement for RK73H1ETTP1003F?

Yes, several 0402 package resistors are pin-compatible. CRCW0402100KFKEDHP is a strong candidate. Others may fit but lack the AEC-Q200 rating, requiring careful review.

What risks should I check before replacing RK73H1ETTP1003F?

The main risk is using a non-AEC-Q200 part in an automotive or high-reliability circuit. Also, verify power rating and temperature range are suitable for your design.
