HAT 500-S Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HAT 500-S is an active Hall Effect open-loop current sensor manufactured by LEM USA Inc., designed for bidirectional AC/DC current measurement up to 500A. This single-channel module delivers ratiometric voltage output with ±1% linearity and accuracy across a frequency range of DC to 25kHz. The part maintains Active product status and is RoHS Compliant, making it suitable for industrial power conversion, motor control, and energy management applications. Substitute parts within the HAT series provide alternative current-sensing ranges while maintaining identical electrical and mechanical specifications, enabling system designers to select appropriate sensing capacity for specific application requirements.

Substitute Part Grouping Explanation

Substitute parts within the HAT series are classified as parametric equivalents based on identical electrical and mechanical specifications with the exception of current-sensing range. The HAT 500-S substitutes are HAT 200-S and HAT 400-S, both manufactured by LEM USA Inc. within the same HAT series.

Substitution logic is determined by the following invariant parameters:

• Sensor Type: Hall Effect, Open Loop
• Number of Channels: 1
• For Measuring: AC/DC
• Output Type: Ratiometric, Voltage
• Frequency Range: DC ~ 25kHz
• Linearity: ±1%
• Accuracy: ±1%
• Voltage - Supply: ±15V
• Response Time: 5µs
• Current - Supply (Max): 15mA
• Operating Temperature Range: -40°C ~ 105°C
• Polarization: Bidirectional
• Mounting Type: Chassis Mount
• Package / Case: Module
• Packaging: Tray
• RoHS Status: RoHS Compliant
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS Code: 9030.33.3800

The variable parameter is Current - Sensing Range, which differs across the three parts: 200A, 400A, and 500A. Selection of substitute parts depends on the maximum current measurement requirement of the target application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—HAT 500-S, HAT 400-S, and HAT 200-S—maintain Active product status and are RoHS Compliant with REACH Unaffected classification, ensuring regulatory compliance for industrial and commercial applications. Selection between these parts is determined solely by the maximum current measurement requirement:

• HAT 500-S: Select for applications requiring current measurement up to 500A
• HAT 400-S: Select for applications requiring current measurement up to 400A
• HAT 200-S: Select for applications requiring current measurement up to 200A

All substitute parts share identical electrical performance characteristics, including ±1% linearity and accuracy, 5µs response time, and DC to 25kHz frequency capability. Mechanical compatibility is maintained across all three parts through identical mounting type (Chassis Mount), package configuration (Module), and supply voltage requirements (±15V). Parts are supplied in Tray packaging and are suitable for direct substitution within the same circuit topology when current-sensing range requirements are met.

Frequently Asked Questions (FAQ)

Q: Can HAT 200-S be used as a substitute for HAT 500-S?

A: HAT 200-S is a parametric equivalent with identical electrical and mechanical specifications except for current-sensing range. It can be substituted only if the application maximum current does not exceed 200A. If the application requires measurement of currents above 200A, HAT 200-S is not suitable.

Q: Can HAT 500-S be used as a substitute for HAT 200-S?

A: HAT 500-S can be used in applications designed for HAT 200-S. The 500A sensing range accommodates all currents within the 200A specification. However, this substitution may result in reduced measurement resolution at lower current levels due to the wider sensing range.

Q: Are all three parts mechanically interchangeable?

A: Yes. HAT 500-S, HAT 400-S, and HAT 200-S share identical mounting type (Chassis Mount), package configuration (Module), and tray packaging. Direct mechanical substitution is possible without modification to mounting hardware or circuit board layout.

Q: What is the difference in electrical performance between these parts?

A: All three parts deliver identical electrical performance: ±1% linearity, ±1% accuracy, 5µs response time, DC to 25kHz frequency range, and ±15V supply voltage. The only difference is the maximum current-sensing range.

Q: Are these parts suitable for both AC and DC current measurement?

A: Yes. All three parts are rated for AC/DC current measurement with bidirectional polarization, enabling measurement of both positive and negative current flow.

Q: What is the supply voltage requirement for these sensors?

A: All three parts require ±15V supply voltage with maximum supply current of 15mA.

Q: Do these parts require special handling or storage conditions?

A: Moisture Sensitivity Level is Not Applicable for all three parts, indicating standard handling and storage conditions are acceptable.
