1. Core Sensing and Output Architecture Differences: Model 20312000101 is explicitly defined as employing a "closed-loop Hall effect" principle with a "ratiometric voltage output." In contrast, 20312000201 is described as "WITH CLAMP," which, based on industry convention, typically indicates an open-loop Hall effect or Rogowski coil type non-contact clamp sensor. There are fundamental differences in their measurement principles, accuracy stability, temperature drift characteristics, and output signal nature. The closed-loop solution generally offers higher accuracy and linearity but imposes specific requirements on power supply and load. The ratiometric voltage output is tied to the supply voltage, necessitating corresponding backend circuit design. 2. Completeness and Verification of Key Performance Parameters: Model 20312000101 provides comprehensive key parameters, including static accuracy (±0.3%), linearity (±0.1%), and dynamic response (1µs). Model 20312000201 lacks this data. Its actual performance—particularly long-term stability, temperature drift, and bandwidth—may be uncertain, or its suitability for the application scenario may be unconfirmed. When considering substitution, it is necessary to verify whether the original application of 20312000201 relies on specific performance characteristics not documented in its specifications. 3. Implicit Requirements for Interface and System Compatibility: Model 20312000101 specifies a 15-24V power supply and ratiometric voltage output, requiring the system's power source and signal acquisition circuitry to be compatible. If the original system (based on 20312000201) operates on a different supply range (e.g., a single 5V rail) or processes different signal types such as current output, hardware circuit modifications and software recalibration would be necessary for substitution. The components are not plug-and-play compatible.
