1. AD5247BKSZ10-RL7 Substitution Conclusion A direct replacement is not viable. The key differences are as follows: The nominal resistance is only 10 kΩ (versus 50 kΩ for the original). This will result in entirely different circuit currents, voltage division ratios, or gains, unless the application is insensitive to absolute resistance value. The minimum operating voltage is 2.7 V (original: 1.8 V), rendering it incompatible with low-voltage systems operating between 1.8 V and 2.7 V. Furthermore, its internal configuration is that of a rheostat (a two-terminal device), whereas the original part is a potentiometer (a three-terminal voltage divider). This fundamental architectural difference prevents it from performing three-terminal voltage division without circuit modifications. Although its wiper resistance (75 Ω) and temperature coefficient (45 ppm/°C) are superior to the original, the critical discrepancies outlined above disqualify it as a suitable direct replacement.
