AI replacement insight
Electrical riskmedium
Resistance and TCR may vary from target.
Package risklow
All candidates share the same 0603 package.
Sourcing risklow
Multiple vendors offer similar alternatives.
Can it be replaced directly?
No verified direct drop-in replacement is available without engineering review. 0603WAF110KT5E is the closest match but lacks a specified TCR value.
Best replacement path
For a near drop-in, use 0603WAF110KT5E after verifying TCR. For applications tolerant of a ~9% resistance change, several 1.0Ω or 1.2Ω options are available.
Main risk
The primary risk is substituting a resistor with a different resistance value (e.g., 1.0Ω or 1.2Ω instead of 1.1Ω), which could alter circuit behavior.
