Alternative Part
1. LM2904AQS-13 Substitution Conclusion
The LM2904AQS-13 is compatible with the original part in package, channel count, and automotive-grade qualification. However, its slew rate (0.3 V/µs) and gain-bandwidth product (700 kHz) are notably lower than those of the LM258YDT (0.6 V/µs and 1.1 MHz), which may fail to meet performance requirements in high-frequency or fast-transient applications. On the other hand, its lower input offset voltage (2 mV) benefits DC accuracy, and its wider supply range (2–36 V) provides greater flexibility. Therefore, it can serve as a substitute in non-high-speed, wide-supply, or less precision-critical scenarios, provided that the bandwidth and slew rate limitations are considered, as they may lead to signal distortion or response delay.
2. BA4558RFJ-GE2 Substitution Conclusion
The BA4558RFJ-GE2 offers superior slew rate (1 V/µs) and gain-bandwidth product (2 MHz) compared to the original part, making it suitable for higher-frequency or fast-signal processing. However, its higher input bias current (60 nA) may introduce additional DC error, and its quiescent current (3 mA) is significantly greater than that of the LM258YDT (700 µA), resulting in substantially higher power consumption. Additionally, its supply voltage range (8–30 V) has a higher minimum, limiting its use in low-voltage applications. Automotive-grade qualification is not mentioned. While its performance can cover the original requirements, trade-offs in power consumption, voltage adaptability, and certification must be evaluated, particularly making it less suitable for low-power or stringent automotive environments.
