1. ADM487EWARZ-REEL7 Substitution Conclusion
The ADM487EWARZ-REEL7 can serve as a viable replacement for the ISL32492EIBZ. However, note that its receiver hysteresis (70 mV) is significantly higher than that of the original part (25 mV). This provides enhanced noise immunity in harsh environments, though it may slightly reduce sensitivity to signal edges. Additionally, its supply voltage range (4.75 V to 5.25 V) is narrower than the original’s (4.5 V to 5.5 V), requiring tighter power supply stability. It also carries Automotive-grade qualification, making it suitable for more demanding applications.
2. SP483EEN-L/TR Substitution Conclusion
The SP483EEN-L/TR is functionally compatible with the ISL32492EIBZ for basic operation. The key difference lies in its receiver hysteresis of 20 mV, which is slightly lower than the original’s 25 mV, resulting in somewhat weaker noise immunity under similar conditions. Its supply voltage range (4.75 V to 5.25 V) is also narrower than the original’s, necessitating careful attention to power supply accuracy. Other parameters such as data rate and package are fully compatible, making it suitable for general industrial applications.
