1. ADM3072EYRZ-REEL7 Substitution Conclusion
The ADM3072EYRZ-REEL7 can serve as a direct, pin-compatible drop-in replacement, but only as a downgrade; it is unsuitable for high-performance applications. The most critical deviations from the original part are its data rate (250 kbps vs. 20 Mbps) and receiver hysteresis (100 mV vs. 25 mV). This device is only viable for low-speed communication scenarios and cannot support the 20 Mbps high-speed data transmission potentially required by the original design. While the increased receiver hysteresis improves noise immunity, this comes at the cost of reduced signal sensitivity. This characteristic is inherent to its low-speed architecture and should not be considered a performance advantage.
2. ADM3075EYRZ-REEL7 Substitution Conclusion
Similarly, the ADM3075EYRZ-REEL7 is only suitable as a direct, pin-compatible downgrade replacement for low-speed applications. Its core differences from the original part also lie in data rate (500 kbps vs. 20 Mbps) and receiver hysteresis (100 mV vs. 25 mV). Although its data rate is double that of the ADM3072, it still falls short by nearly a factor of 40 compared to the original 20 Mbps specification, placing it in an entirely different performance class. Consequently, it is applicable only to low-to-medium speed buses. The higher receiver hysteresis likewise indicates its design intent for harsh but low-speed industrial environments, rendering it incapable of meeting requirements for high speed and precise signal resolution.
