1. ZXRE252BSA-7 Substitution Conclusion
The ZXRE252BSA-7 is a highly viable direct replacement for the TL432AQDBZR. Key differences include a higher initial accuracy (±0.5% vs. ±1%) and a slightly lower cathode operating current (65µA vs. 80µA), which in most applications can provide more precise reference voltage and a marginal reduction in system power consumption. Both devices are fully compatible in terms of package, adjustable voltage range (2.5V/2.495V to 36V), and output current capability (100mA), enabling a pin-to-socket direct replacement.
2. AS431ANTR-E1 Substitution Conclusion
The AS431ANTR-E1 offers advantages over the original part in voltage accuracy (±0.5%) and a clearly specified temperature coefficient (20ppm/°C typical). However, substitution requires careful consideration due to its significantly higher cathode operating current (1mA vs. 80µA). Under the same bias conditions, this device will exhibit substantially higher self-power consumption, potentially impacting system efficiency, increasing thermal dissipation, and necessitating recalculation of the current-limiting resistor value. Therefore, it is suitable only for specific circuits where power consumption is not critical and temperature stability is prioritized, rather than as an unconditional drop-in replacement.
