RT0402BRD073K3L is a precision 3.3kΩ thin-film resistor in a 0402 package, featuring a tight ±0.1% tolerance and a stable 25 ppm/°C TCR. It is ideal for applications requiring high accuracy and thermal stability.

AI replacement insight

Electrical riskhigh

Precision parameters like TCR and tolerance are critical and hard to match.

Package risklow

The 0402 package is standardized, making physical replacement straightforward.

Can it be replaced directly?

No exact drop-in replacement is identified. The closest options have different TCRs or resistance values, requiring engineering review.

Best replacement path

Find a thin-film 0402 resistor with 3.3kΩ, ≤0.1% tolerance, and ≤25 ppm/°C TCR.

Main risk

The main risk is compromising circuit precision by using a substitute with a higher TCR or wider tolerance.
