1. LM358PW Substitution Conclusion
The LM358PW can generally serve as a replacement for the original part, with two key differences requiring attention. First, its maximum supply voltage is 30V (compared to 36V for the original). Therefore, it is not a suitable substitute if the application circuit operates near or above 30V. Second, the input offset voltage is 3mV (original: 2mV), which may introduce slightly greater error in applications demanding high-precision DC amplification. All other critical parameters—including gain bandwidth product (700kHz), slew rate (0.3V/µs), and output current (40mA)—match the original specifications. Its quiescent current (500µA) is lower, which helps reduce power consumption. The device comes in an 8-TSSOP package (4.40mm width). Note that its pinout differs from the original 8-MSOP package (3.00mm width), so PCB compatibility must be verified.
2. BA2904SFV-E2 Substitution Conclusion
The BA2904SFV-E2 represents a noticeable performance downgrade as a substitute and should be evaluated carefully. Its gain bandwidth product (500kHz) and slew rate (0.2V/µs) are both lower than the original specifications (700kHz and 0.3V/µs, respectively), resulting in reduced high-frequency signal response and bandwidth capability. This makes it unsuitable for circuits with stringent frequency-response requirements. The output current is 30mA (original: 40mA), indicating weaker drive capability. The quiescent current is specified as 500µA, though it is not stated whether this is per channel or total. If this is the total for both channels, it would be an improvement over the original's 700µA per channel. The package is an 8-LSSOP (4.40mm wide), which differs in size from the original. Consider this substitute only in low-frequency, low-power applications where bandwidth, slew rate, and output current requirements are relaxed.
