AI replacement insight
Electrical riskmedium
Ensure TCR and tolerance match application needs. Many alternatives have weaker specs.
Package risklow
Most alternatives are axial, but body dimensions and lead spacing should be checked.
Can it be replaced directly?
CCO's MF2WS-1MΩ±1% T is a strong candidate for replacement, offering a higher power rating while matching resistance, tolerance, and TCR. A review of its physical dimensions is necessary.
Best replacement path
Upgrade power rating with a part like CCO MF2WS-1MΩ±1% T, which meets or exceeds all key specifications while requiring physical dimension verification.
Main risk
Substituting with a part that has a lower power rating, wider tolerance, or higher TCR, which can affect circuit performance and reliability.
