Is there a pin-compatible replacement for RT0402BRD07499RL?

Yes, AT0402BRD07499RL from the same manufacturer, Yageo, shares the same 0402 package, 499Ω resistance, 0.1% tolerance, and 25ppm/°C TCR, making it a likely pin-compatible option.

What risks should I check before replacing RT0402BRD07499RL?

When replacing a precision resistor, verify tolerance (±0.1%), TCR (25ppm/°C), and technology (Thin Film). Alternatives with wider tolerance, higher TCR, or Thick Film technology may impact circuit performance and stability.
