Parametric alternative from a major manufacturer with a close standard resistance value (1kΩ vs 1.02kΩ).
Best Alternatives to 0603WAF1021T5E
0603WAF1021T5E is a 1.02kΩ, 1%, 0.1W thick film resistor in a 0603 package. While direct replacements may be limited, numerous parametric alternatives with nearby standard resistance values like 1kΩ and 1.05kΩ are widely available.
AI replacement insight
Electrical risklow
Resistance value differs slightly. Power, voltage, and tolerance match.
Package risklow
All suggested alternatives use the same 0603 package.
Sourcing risklow
Alternatives are common values from multiple major manufacturers, improving availability.
Can it be replaced directly?
No exact direct replacement was found. However, several parametric alternatives with very close resistance values (1kΩ, 1.05kΩ) are available and should be suitable for most applications after review.
Best replacement path
Use a common 1kΩ or 1.05kΩ 1% 0603 resistor like CRCW06031K00FKEAC or WR06X1001FTL.
Main risk
The primary risk is the small deviation in resistance value (typically <3%), which could affect the performance of precision analog circuits. Verification is recommended.
