UNI-ROYAL
Functional alternate from UNI-ROYAL with higher power in a larger 0603 package; not a drop-in replacement.
FRC0402F1100TS is a general-purpose 110Ω 1% 0402 chip resistor. While direct drop-in replacements are limited by strict power rules, functional alternatives in larger packages are available.
Alternatives are in a larger 0603 package, requiring a new PCB layout.
Electrical parameters of functional alternates are matched or improved.
No direct pin-for-pin replacements were found that meet the strict 1.5x power rating engineering rule. Parts with the same power rating exist but are not recommended without relaxing this safety margin.
Use a functional alternate in a larger 0603 package like FRC0603F1100TS, which offers a higher power rating but requires a new PCB layout.
Package mismatch is the primary risk, requiring board redesign. No drop-in replacements meet the specified engineering safety margins.
