AI replacement insight
Electrical risklow
For pin-compatible parts. Medium for parts with different tech/tolerance.
Package risklow
All candidates are in the standard 0402 package.
Sourcing risklow
This is a very common resistor value and package.
Can it be replaced directly?
Yes, several pin-compatible 100Ω, 1%, 0.0625W, 0402 resistors exist, such as CRCW0402100RFKEDC from Vishay.
Best replacement path
Use a pin-compatible part like Vishay's CRCW0402100RFKEDC for a direct, reliable replacement from a major manufacturer.
Main risk
The main risk is substituting a part with incorrect tolerance (e.g., 5%) or technology (Thin Film vs. Thick Film) without design review.
