Original Part
Alternative Part
1. TLE2072IDR Substitution Conclusion
The TLE2072IDR can functionally substitute the LM358ADR2G, but critical differences must be considered: it employs J-FET input technology, offering significantly superior performance compared to the original part (input bias current of 1 pA vs. 45 nA, offset voltage of 300 µV vs. 2 mV, bandwidth of 10 MHz vs. 1 MHz, and slew rate of 45 V/µs vs. unspecified low speed). It provides clear advantages in high-impedance signal, high-precision, and high-speed applications. However, this comes at the cost of a higher minimum supply voltage (4.5 V vs. 3 V) and higher quiescent current (3.1 mA/ch vs. 0.8 mA/ch), which may preclude its use in ultra-low-voltage or extremely low-power scenarios.
2. BA3404F-E2 Substitution Conclusion
The BA3404F-E2 can serve as an approximate substitute for the LM358ADR2G, with similar basic parameters (bandwidth of 1.2 MHz vs. 1 MHz, offset voltage of 2 mV for both). Its push-pull output stage may improve output drive capability. Key differences include a slightly narrower supply range (4–36 V vs. 3–32 V), lower output current (30 mA vs. 40 mA), and a slightly larger package width (4.40 mm vs. 3.90 mm). Compatibility should be verified in applications with lower supply voltages or stringent maximum output current requirements, and PCB layout must account for the package size difference.
