HX 50-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HX 50-P is a 50A AC/DC Hall Effect current sensor manufactured by LEM USA Inc., configured as a single-channel open-loop bidirectional module with ratiometric voltage output. This component is classified as "Not For New Designs," indicating it has reached end-of-life status in the manufacturer's product portfolio. Applications requiring current sensing functionality with the HX 50-P specification must evaluate equivalent substitute parts from the HX series to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts within the HX series maintain electrical and mechanical compatibility with the HX 50-P based on the following criteria:

Common Parameters Across All Substitutes:

• Sensor Technology: Hall Effect, Open Loop
• Measurement Capability: AC/DC bidirectional
• Output Configuration: Ratiometric voltage output
• Single Channel Architecture
• Frequency Response: 50kHz
• Linearity: ±1%
• Accuracy: ±1%
• Supply Voltage: ±15V
• Response Time: 3µs
• Maximum Supply Current: 15mA
• Operating Temperature Range: -25°C to 85°C
• Mounting: Through Hole Module
• Compliance: RoHS Compliant, REACH Unaffected

Variable Parameter:

• Current Sensing Range: Differs by model (3A, 5A, 10A, 15A, 20A, 50A)

The HX series substitutes are functionally equivalent when the application current requirement does not exceed the rated sensing range of the substitute part. Selection is determined solely by the maximum current to be measured in the circuit.

Parameter Comparison

Engineering Selection Recommendations

All parts in the HX series share identical electrical characteristics, compliance certifications, and mechanical form factors. Selection of a substitute part is determined exclusively by the maximum current measurement requirement of the application circuit.

Selection Criteria:

• HX 03-P: Applications measuring currents up to 3A
• HX 05-P: Applications measuring currents up to 5A
• HX 10-P: Applications measuring currents up to 10A
• HX 15-P: Applications measuring currents up to 15A
• HX 20-P: Applications measuring currents up to 20A
• HX 50-P: Applications measuring currents up to 50A

All substitute parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory alignment with the original HX 50-P specification. The "Not For New Designs" status applies uniformly across the HX series, indicating that all models have reached end-of-life classification. For new design initiatives, consultation with LEM USA Inc. regarding current-generation Hall Effect sensor alternatives is required.

Frequently Asked Questions (FAQ)

Q: Can HX 03-P, HX 05-P, HX 10-P, HX 15-P, or HX 20-P be used as direct replacements for HX 50-P in existing circuits?

A: Direct substitution is possible only if the maximum current in the circuit does not exceed the rated sensing range of the substitute part. All HX series sensors share identical electrical output characteristics, supply requirements, response time, and mounting configuration. If circuit current exceeds the substitute part's rating, the sensor will saturate and produce inaccurate measurements.

Q: What is the primary difference between HX 50-P and the lower-rated HX series models?

A: The sole difference is the current sensing range. All other electrical parameters, including frequency response, accuracy, linearity, supply voltage, response time, and output type, are identical across the HX series.

Q: Are the HX series sensors pin-compatible?

A: Yes. All HX series sensors are configured as single-channel through-hole modules with identical mechanical form factors and mounting requirements.

Q: What does "Not For New Designs" status mean for the HX 50-P and substitute parts?

A: This designation indicates that LEM USA Inc. has discontinued active development and marketing of these models. Existing inventory remains available, but these parts should not be specified in new product designs. Alternative current sensor solutions should be evaluated for new applications.

Q: Are all HX series parts RoHS compliant?

A: Yes. All HX series sensors, including HX 50-P and all listed substitutes, are RoHS compliant and REACH unaffected.

Q: Can a lower-rated HX sensor be used in an application designed for HX 50-P if the actual current is lower?

A: Yes, provided the actual circuit current does not exceed the substitute part's rated sensing range. The substitute will deliver identical measurement accuracy and response characteristics within its rated range.
