Is there a pin-compatible replacement for RS-05K302JT?

Yes, several 0805 package resistors are pin-compatible. RS-05K3001FT is a strong match. Other options like Yageo's RC0805JR-073KL are also pin-compatible but have parametric differences that require review.

What risks should I check before replacing RS-05K302JT?

When substituting, verify the tolerance and Temperature Coefficient (TCR). A tighter tolerance (e.g., 1%) is usually a safe upgrade, but a weaker TCR (e.g., ±200ppm/°C) can impact circuit stability over temperature.
