1. TL972QPWRQ1 Substitution Conclusion The TL972QPWRQ1 is fully aligned with the TS972IPT in key parameters—bandwidth, input bias current, offset voltage, minimum supply voltage, and package—and both comply with the AEC-Q100 automotive-grade standard, establishing a foundation for direct substitution. The primary differences are as follows: the TL972QPWRQ1 offers a slightly higher slew rate (5V/µs vs. 4V/µs), providing marginally better large-signal dynamic response; however, its output current is lower (80mA vs. 100mA), resulting in slightly weaker heavy-load drive capability. Additionally, the TL972QPWRQ1 supports a higher maximum supply voltage (12V vs. 10V), offering broader adaptability. In summary, if the application does not require the full 100mA output current and is not strictly limited to a supply voltage of 10V or below, the TL972QPWRQ1 can be considered a qualified substitute with comparable performance. It is particularly suitable for direct replacement in automotive electronic systems.
