Is there a pin-compatible replacement for RTT0275R0FTH?

Yes, several 0402 package resistors are pin-compatible. However, you must verify electrical parameters. For example, RT0402BRD0775RL is pin-compatible but uses a different (thin film) technology which may affect performance.

What risks should I check before replacing RTT0275R0FTH?

Key risks include tolerance, technology, and resistance value. A wider tolerance (e.g., ±5%) may affect circuit accuracy. A different technology (thin film vs. thick film) can alter pulse handling and noise characteristics. Always verify substitute parameters meet your design requirements.
