1. LM2904ATH-13 Substitution Conclusion
From a general substitution perspective, the LM2904ATH-13 can replace the LM358PWRG3. This is due to its superior input offset voltage (1mV vs. 3mV) and wider supply voltage range (36V vs. 30V). In applications requiring slightly higher DC precision, such as sensor signal conditioning, it provides lower initial error and better tolerance to supply voltage variations. The trade-off is its higher quiescent current (700µA vs. 500µA). In power-sensitive applications like battery-powered systems, this substitution would increase the overall standby power consumption by approximately 40%, which must be evaluated.
2. LM2904TH-13 Substitution Conclusion
The LM2904TH-13 is largely a viable substitute for the LM358PWRG3. Key parameters such as bandwidth and slew rate are identical, and the packages are compatible. The differences similarly lie in the input offset voltage (2mV vs. 3mV, offering a slight improvement) and the quiescent current (700µA vs. 500µA, a significant increase). In most general-purpose amplification and comparator circuits, the substitution is functionally compatible and can yield a minor improvement in precision. However, it similarly introduces the issue of increased static power dissipation. Its overall characteristics position it between the original part and the LM2904ATH-13, making it a compromise alternative.
