1. LM358ST Substitution Conclusion It may only serve as an emergency substitute in non‑critical DC or low‑frequency circuits (well below 100kHz) where performance requirements are extremely relaxed, though with a significant risk of performance degradation. The key differences compared to the MC33078DGKT lie in bandwidth/speed (gain‑bandwidth product: 800kHz vs. 16MHz) and slew rate (0.6V/µs vs. 7V/µs), which differ by more than an order of magnitude. The LM358ST is entirely incapable of handling the mid‑to‑high‑frequency signals or fast transients required by the original design, leading to severe signal distortion. Moreover, its input offset voltage (2mV vs. 150µV) is over ten times worse, introducing non‑negligible errors in DC amplification or precision measurement applications. Although it offers lower quiescent current and is automotive‑qualified, these advantages cannot compensate for the lack of critical performance. Therefore, substitution is not recommended in the vast majority of cases.
