1. ADM487EWARZ Substitution Conclusion
This device can be considered a functional substitute within the same category, but critical differences exist. Its data rate (250 kbps) is significantly lower than the original part (15 Mbps), limiting it to low-speed communication scenarios and making it unsuitable for high-speed data transmission requirements. The receiver hysteresis (70 mV) is higher than the original (25 mV). While this offers an advantage in noise immunity, it may compromise sensitivity to low-amplitude signals. The supply voltage range (4.75 V to 5.25 V) is narrower than the original's (4.5 V to 5.5 V), imposing stricter requirements on power supply stability. Furthermore, its Automotive-grade qualification is suitable for automotive applications but may be redundant if the original design targeted general industrial use. Direct substitution is only recommended for low-speed, high-noise environments or automotive projects, and only after confirming power supply compatibility. Otherwise, it is not advised.
2. ADM487EWARZ-REEL7 Substitution Conclusion
This model is electrically identical to the ADM487EWARZ in all key parameters (data rate: 250 kbps, hysteresis: 70 mV, supply range: 4.75 V to 5.25 V). The only difference is the packaging format (REEL7 tape-and-reel), which is intended for automated surface-mount assembly. The substitution feasibility follows the same conclusion as above: it is only suitable for low-speed, high-immunity, or automotive electronics applications, and the power supply accuracy must be evaluated to ensure compliance. It cannot be used as a replacement if the original design relies on high-speed communication.
