1. LM358DR Substitution Conclusion
The LM358DR can directly replace the LM358ADR, as both share identical core architecture, package, and most key parameters (including supply range, bandwidth, slew rate, and output current). The primary differences are that the LM358DR exhibits slightly higher input bias current (20 nA vs. 15 nA) and input offset voltage (3 mV vs. 2 mV) compared to the original part. In applications requiring very high precision or microvolt‑level signal conditioning, this substitution may introduce marginally greater input error and DC offset. However, for the vast majority of use cases—such as general‑purpose amplification, comparator circuits, and filters—these performance variations are typically negligible, and the substitution remains fully viable.
2. LM2904DR Substitution Conclusion
The LM2904DR can serve as a replacement for the LM358ADR, but with an important limitation: its maximum supply voltage is 26V, which is lower than the original part’s 30V rating. If the original design operates close to or above 26V (for example, in 24V industrial systems where headroom is required), there is a risk of overvoltage damage. Additionally, its input bias current and offset voltage are the same as those of the LM358DR and are slightly inferior to the original specification. Substitutability is highly dependent on the application voltage—the LM2904DR can be used directly in circuits with a supply voltage ≤26V where input precision is not critical. Otherwise, voltage compatibility or derating must be reevaluated.
