1. LM358S-13 Substitution Conclusion
Substitution is feasible, but significant technical differences exist and must be carefully evaluated based on the application. The key distinctions are as follows: The LM358S-13 is a standard BJT-input amplifier. Its input bias current (45 nA) is three orders of magnitude higher than that of the original JFET-input TL062ID (30 pA). In circuits such as high-impedance signal sources, integrators, or precision current sensing, this will introduce greater input error and drift. Its slew rate is unspecified but is typically lower than the TL062ID's 3.5 V/µs, limiting large-signal high-frequency response. However, the LM358S-13 offers a wider supply voltage range (3 V to 32 V), lower input offset voltage (2 mV), and stronger output drive capability (40 mA). If the application is not sensitive to input bias current and operates at lower voltages or requires greater load drive, it can serve as a cost-effective alternative.
2. AS358MTR-E1 Substitution Conclusion
Substitution is also possible, but similarly involves critical technical differences that must be decided based on key application parameters. Compared to the original part, the AS358MTR-E1 also employs a standard BJT-input architecture. Its input bias current (20 nA) is significantly higher than the JFET input of the TL062ID (30 pA), making it likewise unsuitable for precision or high-impedance circuits extremely sensitive to input current. Furthermore, its unspecified slew rate typically implies that its large-signal bandwidth performance is likely inferior to the original part. Its advantages include a wider supply voltage range (3 V to 36 V), lower input offset voltage (2 mV), and higher output current capability (40 mA). If the original design does not strictly require extremely low input bias current and high slew rate, but instead prioritizes wide supply adaptability and drive strength, then this part can be considered a viable alternative.
