1. TL072CDT Substitution Conclusion The TL072CDT is generally compatible with the OP282GSZ-REEL7 in terms of package and supply voltage range, but significant differences in key parameters make direct substitution inadvisable. The TL072’s input bias current (20 pA) is an order of magnitude higher than that of the OP282 (3 pA), and its input offset voltage (3 mV) is substantially greater than the OP282’s 200 µV. In applications sensitive to input errors—such as precision amplification or high-impedance sensor signal conditioning—the TL072 may introduce considerable accuracy degradation. Its advantages include a higher slew rate (16 V/µs) and stronger output current capability (40 mA), making it suitable for driving capacitive loads or general-purpose audio and medium-speed circuits requiring fast transient response. Additionally, it carries automotive-grade qualification (AEC-Q100), which suits harsh operating environments. If the original design does not demand high precision but emphasizes cost or reliability certification, substitution could be considered, though a thorough reassessment of error budgets and power consumption (quiescent current 1.4 mA vs. OP282’s 420 µA per dual channel) is necessary.
