AI replacement insight
Electrical riskmedium
Most candidates have different resistance values (49.9Ω or 51Ω) or weaker tolerance/TCR.
Package risklow
All candidates are in the same 0402 package, ensuring physical compatibility.
Sourcing risklow
The target and candidates are common resistor values from multiple vendors.
Can it be replaced directly?
No exact drop-in replacement was found in this batch. All candidates require review for parametric differences like resistance value, tolerance, or temperature coefficient (TCR).
Best replacement path
Consider upgrade path candidates like RT0402BRD0749R9L for better performance, but verify the 49.9Ω resistance is acceptable in your circuit.
Main risk
The primary risk is substituting with a part that has a different resistance value or a wider tolerance, which can affect circuit performance.
