AI replacement insight
Electrical riskmedium
Resistance value differs by ~9% and technology may differ.
Package risklow
All candidates share the same 0805 package.
Can it be replaced directly?
No direct, drop-in replacement was found. All candidates have a different resistance value and/or technology.
Best replacement path
RTT051001FTP is the most similar, only differing in resistance. For higher precision, Yageo's RT series are upgrades but also require validating the resistance and technology change.
Main risk
Resistance value mismatch (~9%) is the main risk across all candidates.
