1. ISL83072EIBZA Substitution Conclusion
Direct substitution is not recommended. The primary discrepancies lie in the supply voltage (3.3V vs. 5V) and the data rate (250 kbps vs. 20 Mbps). Voltage incompatibility is critical: if the original circuit operates on a 5V system, directly replacing with the ISL83072EIBZA would likely cause malfunction or permanent damage. Furthermore, the two-order-of-magnitude difference in data rate indicates that this device is only suitable for low-speed communication applications, making it incapable of meeting the 20 Mbps high-speed transmission requirement of the original part. Therefore, substitution feasibility is low.
2. SP3088EEN-L/TR Substitution Conclusion
High direct substitution feasibility is confirmed. Key parameters, including supply voltage range (4.5V–5.5V) and data rate (20 Mbps), are fully aligned with the original component, ensuring both electrical compatibility and matched communication performance. The difference lies in receiver hysteresis (100 mV vs. 30 mV), which grants the SP3088EEN-L/TR stronger noise immunity. This enables more reliable data detection in electrically harsh environments with significant signal interference or distortion. Such a deviation is generally regarded as a performance enhancement rather than a limitation. Combined with pin-to-pin compatibility, this device serves as a suitable and improved alternative.
