1. ADM3072EYRZ-REEL7 Substitution Conclusion
Not a direct substitute. While its supply voltage, interface protocol, and package are fully compatible with the SP3494CN-L, the core discrepancy lies in its significantly lower data rate (250kbps vs. 2.5Mbps), which is only one-tenth that of the original part. In the original system requiring high-speed communication, using this device would result in communication failure or severe performance degradation. Furthermore, its receiver hysteresis is higher (100mV vs. 20mV). Although this can enhance noise immunity in harsh environments, it cannot compensate for the critical flaw in data rate.
2. ADM3075EYRZ-REEL7 Substitution Conclusion
Substitution is possible under specific conditions, but system compatibility must be evaluated. The differences between this device and the original model are similarly a significantly lower data rate (500kbps vs. 2.5Mbps) and higher receiver hysteresis (100mV vs. 20mV). The data rate, reduced to one-fifth, is only suitable for applications where the original design has substantial bandwidth headroom or where the communication speed can be reconfigured down to 500kbps or below. The higher hysteresis is a favorable difference, improving signal reception robustness. If the system can accept operation at the reduced speed, substitution is viable; otherwise, it is not recommended.
