AC0805FR-7W330RL
Yageo
Needs validationmedium risk
A higher power (0.25W) AEC-Q200 alternative, but with a weaker TCR of ±100ppm/°C.
Best Alternatives to ARG05FTC3300
Find substitutes for the Viking Tech ARG05FTC3300, a 330Ω 1% 0.125W 0805 resistor. Key considerations for replacement include matching its high-precision TCR of ±25ppm/°C and power rating.
AI replacement insight
Electrical riskhigh
TCR mismatch is significant (±25ppm/°C vs ±100ppm/°C). Performance over temperature will 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 weaker Temperature Coefficient of Resistance (TCR), which is a critical parameter for this precision part.
Best replacement path
For higher power handling, Yageo AC0805FR-7W330RL (0.25W) is a potential upgrade. If TCR is critical, a new search for thin-film resistors with ±25ppm/°C is required.
Main risk
The primary risk is the TCR mismatch. The target is a precision ±25ppm/°C resistor, while all candidates are ±100ppm/°C, which may affect circuit stability over temperature.
