FOJAN
A form-fit compatible 1.8kΩ resistor with wider tolerance and higher TCR; requires engineering review.
The Panasonic ERA6AEB182V is a high-precision, AEC-Q200 qualified thin film resistor. Finding a direct replacement requires matching its tight tolerance (±0.1%) and low temperature coefficient (±25 ppm/°C).
Mismatched tolerance, TCR, and technology will degrade circuit precision and stability.
All candidates use the same standard 0805 package.
High-precision components can have more limited availability than general-purpose ones.
No direct, verified drop-in replacements are presented. All candidates are parametrically relaxed and require engineering validation.
Search for thin film, 0805, 1.8kΩ resistors with tolerance ≤0.1% and TCR ≤25 ppm/°C, preferably with AEC-Q200 qualification.
The primary risk is substituting a high-precision thin film resistor with a general-purpose thick film part, leading to loss of accuracy and temperature stability.
