Near-identical 90.9Ω resistor from the same manufacturer; requires review of power dissipation margin.
FRC0402F91R0TS is a general-purpose 91Ω 1/16W 0402 resistor. Alternatives exist with identical ratings or with upgraded power handling, but may require verifying resistance tolerance or power dissipation margins.
Resistance or power rating differences require verification.
All suggested alternatives are in the same 0402 package.
No drop-in replacement meeting all engineering guidelines (notably the 1.5x power rule) was found. FRC0402F90R9TS is the closest functional match but shares the same power rating.
For precision, FRC0402F90R9TS is nearly identical but requires checking power margin. For robust designs, consider power-upgraded parts like ERJPA2F1000X (100Ω) after verifying resistance impact.
The primary risk is either using a part with a different resistance value (e.g., 100Ω or 82Ω) or one that lacks an upgraded power rating, which may reduce long-term reliability.
