Needs validationhigh risk
A general-purpose 100Ω 0402 thick-film resistor. Differs significantly from the target's precision specs.
Best Alternatives to AR02BTC1000
AR02BTC1000 is a high-precision 100Ω thin-film resistor. Finding a substitute requires careful evaluation of tolerance and technology, as no direct drop-in replacements with identical precision were found.
AI replacement insight
Electrical riskhigh
Tolerance and technology mismatches can cause circuit failure in precision applications.
Package risklow
All viable candidates use the same 0402 package.
Can it be replaced directly?
No direct, pin-to-pin replacement with identical precision (±0.1% tolerance) was found. All candidates have wider tolerances and may use different resistor technology.
Best replacement path
Find a thin-film 0402 100Ω resistor with ≤±0.1% tolerance. If unavailable, TC02G1000FT is the closest option but requires tolerance analysis.
Main risk
The primary risk is substituting a lower-precision (±1%) or thick-film resistor, which can degrade circuit performance, stability, and accuracy.
