1. AD5247BKSZ10-2RL7 Substitution Conclusion The AD5247BKSZ10-2RL7 can serve as a replacement for the original part in certain applications, but key differences must be noted: It is configured as a rheostat, whereas the original device is a potentiometer, making it more suitable for variable-resistance applications rather than voltage-divider circuits, which may affect signal-processing design; its operating voltage range is 2.7 V to 5.5 V, with a minimum supply voltage higher than the original’s 1.8 V, thus it is not suitable for low-voltage systems (e.g., 1.8 V–2.7 V); its temperature coefficient is 45 ppm/°C, better than the original’s 150 ppm/°C, offering improved temperature stability and accuracy; its typical wiper resistance is 75 Ω, lower than the original’s 155 Ω, which reduces additional impedance in the circuit and enhances linearity. In summary, if the application permits a rheostat configuration, the supply voltage is at least 2.7 V, and temperature stability is a priority, this device can be substituted; otherwise, circuit compatibility should be re-evaluated.
