1. LM358PT Substitution Conclusion
Based on key parameters and package, the LM358PT slightly outperforms the original part in bandwidth (800 kHz vs. 700 kHz) and slew rate (0.6V/µs vs. 0.3V/µs), while maintaining the same automotive-grade qualification. However, its supply voltage range (3V to 30V) is narrower than the original's (2V to 36V), and its output drive capability (30mA vs. 40mA) is slightly weaker. The LM358PT can serve as a direct replacement, but only in applications where the supply voltage is above 3V and does not exceed 30V, and where the output load current requirement is not demanding. For designs requiring a lower startup voltage (such as a 2V single-supply system) or higher output voltage swing, this substitution carries risk.
2. LM258WYPT Substitution Conclusion
The LM258WYPT offers significant performance advantages over the original part in core specifications, featuring a higher gain bandwidth product (1.1 MHz), a faster slew rate (0.6V/µs), and stronger output drive current (60mA), while sharing the same package and automotive-grade certification. Similarly, its supply voltage range (3V to 30V) is narrower than the original's (2V to 36V). For applications operating within a 3V to 30V supply range, the LM258WYPT is a high-performance upgrade alternative, providing improved AC response and load drive capability. It cannot cover the wider voltage range supported by the original part and is not a direct replacement in scenarios requiring 2V low-voltage startup or operation near 36V high voltage.
