1. LM2904YST Substitution Conclusion
The LM2904YST can generally serve as a substitute for the original part. Key differences include: a slightly lower gain-bandwidth product (700 kHz vs. 1 MHz), which may affect high-frequency small-signal accuracy; a somewhat weaker output current (30 mA vs. 40 mA), limiting drive capability; superior input bias current (20 nA vs. 45 nA), beneficial for high-impedance signal applications; and a marginally lower supply voltage ceiling (30 V vs. 32 V) with minimal practical impact. Its advantages include AEC-Q100 automotive qualification and a clearly specified slew rate (0.6 V/µs), making it suitable for automotive or high-reliability applications. Substitution is acceptable if the application does not demand stringent bandwidth or drive current.
2. AS358MMTR-G1 Substitution Conclusion
The AS358MMTR-G1 is a viable substitute for the original part. The main differences are the unspecified gain-bandwidth product and slew rate, introducing some risk in high-frequency performance clarity. However, it offers better input bias current (20 nA vs. 45 nA) and a wider supply voltage upper limit (36 V vs. 32 V), providing greater adaptability. Other parameters, such as output current (40 mA) and basic architecture, remain well-matched. This substitution is recommended if high-frequency precision amplification is not critical, and wide supply voltage range or low input bias current is prioritized.
