AI replacement insight
Electrical riskhigh
Degradation in tolerance and TCR will affect circuit precision and stability.
Package risklow
All candidates share the same 2512 package, ensuring physical compatibility.
Can it be replaced directly?
No direct, pin-to-pin replacement with matching ±0.1% tolerance and ±15ppm/°C TCR was found. All candidates require careful review of precision requirements.
Best replacement path
For applications tolerant of wider specifications, VMS-R010-1.0-U offers higher power and similar TCR but with 1% resistance tolerance.
Main risk
The primary risk is the significant relaxation in resistance tolerance (from ±0.1% to ±1%) and TCR, which can impact measurement accuracy.
