1. TL082ACD Substitution Conclusion
Direct substitution is not recommended. The primary limitation is its supply voltage range (±5V to ±15V), which is significantly narrower than the original part's (±18V). In designs utilizing higher supply voltages (e.g., above ±15V), the TL082ACD will fail to operate or may be damaged. While it offers slight improvements in input characteristics (bias current, offset voltage), this comes at the cost of reduced bandwidth (3 MHz vs. 4 MHz) and weaker output drive capability (10 mA vs. 17 mA). Substitution should only be considered if the original system's supply voltage is confirmed to be within the TL082ACD's specified range and there are no stringent requirements for bandwidth and drive current. Otherwise, the risk is significant.
2. TLE2082ACD Substitution Conclusion
This device is an excellent candidate for direct substitution from an electrical performance standpoint and represents a performance upgrade. Its key advantages include: a wider supply voltage range (±2.25V to ±19V) that fully covers and exceeds the original part, ensuring compatibility; and substantially improved key performance parameters, such as higher bandwidth (10 MHz vs. 4 MHz), faster slew rate (40V/µs vs. 13V/µs), lower input offset voltage (700µV vs. 5mV), and stronger output drive capability (48 mA vs. 17 mA). The only notable difference is a slightly higher quiescent current. For the vast majority of applications, its superior performance and voltage compatibility make it an ideal replacement.
