2. BA3472F-E2 Substitution Conclusion The BA3472F-E2 is electrically feasible as a substitute in basic terms, but the application context requires careful evaluation. Its advantages include a wider supply voltage range (3–36V), which fully covers and exceeds that of the original part, along with significantly improved bandwidth (4MHz) and slew rate (10V/µs). Key differences are: its output drive capability (30mA) is lower than the original part’s (40mA), which could become a bottleneck when driving heavy loads; its quiescent current (4mA) remains nearly six times higher than the original’s, making it unacceptable in power-sensitive applications; and its input offset voltage (1.5mV) is slightly worse than the original (1mV), potentially requiring recalibration in circuits demanding high DC precision. Like the original part, it also lacks stated automotive-grade certification, and therefore cannot be used in applications requiring AEC-Q100 compliance.
