1. LM358PW Substitution Conclusion
The LM358PW can generally serve as a replacement for the original part, but key performance deratings must be considered. The primary differences are its slew rate (0.3 V/µs) and gain-bandwidth product (700 kHz), both approximately half those of the original part (0.6 V/µs, 1.1 MHz). This significantly reduces signal processing speed and frequency response, making it unsuitable for applications requiring high dynamic performance. Additionally, its input offset voltage (3 mV) is slightly higher than the original (2 mV), which may affect DC accuracy. Furthermore, the LM358PW lacks AEC-Q100 automotive qualification and is therefore non-compliant for automotive or other high-reliability applications. Since both parts share the same supply voltage range (3–30 V) and package compatibility, substitution is acceptable only in general industrial or consumer low-speed, non-automotive applications.
2. LM2904PWRG3 Substitution Conclusion
The LM2904PWRG3 differs significantly from the original part, and substitution requires careful evaluation of application conditions. Its lower slew rate (0.3 V/µs) and gain-bandwidth product (700 kHz) limit high-speed signal processing capability, and its input offset voltage (3 mV) is also worse than the original (2 mV). Most critically, its maximum supply voltage is 26 V, compared to 30 V for the original part. Systems operating near 30 V may experience reliability issues. Moreover, this variant is not specified with AEC-Q100 qualification and cannot meet automotive requirements. Although it shares the same package and offers lower quiescent current, it is recommended only for substitution in non-automotive applications with supply voltages ≤26 V and where bandwidth and slew rate are not critical.
