HAL 300-S Current Sensor Equivalent & Substitute Parts

Part Overview

The HAL 300-S is an active Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications requiring 300A sensing capacity. This single-channel, open-loop bidirectional module delivers voltage output with ±1% accuracy and operates across industrial temperature ranges. The product maintains Active status with full RoHS compliance and REACH unaffected designation, ensuring regulatory compatibility for industrial deployment.

Substitute parts become necessary when application requirements specify lower current measurement ranges, inventory constraints limit primary part availability, or system design modifications reduce current sensing demands below 300A specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HAL 300-S is determined by strict parameter matching across the HAL series. All substitute parts must maintain identical specifications in the following critical categories:

Mandatory Matching Parameters:

• Sensor Type: Hall Effect, Open Loop
• Output Type: Voltage
• Measurement Capability: AC/DC
• Number of Channels: 1
• Frequency Response: DC ~ 50kHz
• Accuracy: ±1%
• Linearity: ±0.5%
• Supply Voltage: ±15V
• Response Time: 3µs
• Operating Temperature: -25°C ~ 85°C
• Polarization: Bidirectional
• Mounting Type: Chassis Mount
• Package Type: Module
• RoHS Status: RoHS Compliant
• Product Status: Active

Variable Parameter (Substitution Basis):

• Current Sensing Range: 50A, 200A (lower ranges only)

The HAL 300-S accepts substitution only with lower current-sensing models from the same HAL series. Substitution occurs when application requirements specify reduced current measurement capacity. The HAL 50-S and HAL 200-S maintain complete electrical and mechanical compatibility with the HAL 300-S across all other parameters.

Engineering Selection Recommendations

HAL 300-S Primary Selection Criteria: Select the HAL 300-S when application requirements specify 300A current measurement capacity with single-channel Hall Effect sensing. This part maintains Active product status with full RoHS compliance and REACH unaffected designation, ensuring regulatory compatibility across industrial markets.

HAL 200-S Substitution Criteria: The HAL 200-S substitutes for the HAL 300-S when application current measurement demands reduce to 200A maximum. All electrical characteristics, frequency response, accuracy specifications, and compliance certifications remain identical. This substitution applies to system redesigns or applications with lower current requirements.

HAL 50-S Substitution Criteria: The HAL 50-S substitutes for the HAL 300-S when application current measurement demands reduce to 50A maximum. All electrical characteristics, frequency response, accuracy specifications, and compliance certifications remain identical. This substitution applies to low-current measurement applications or system modifications requiring reduced sensing capacity.

Compliance Assurance: All three parts maintain identical RoHS compliance status and REACH unaffected designation. Selection between HAL 300-S, HAL 200-S, and HAL 50-S does not introduce regulatory compliance variations. All parts support industrial temperature operation from -25°C to 85°C with identical response characteristics.

Frequently Asked Questions (FAQ)

Q: Can HAL 200-S or HAL 50-S replace HAL 300-S in existing designs?

A: Substitution is valid only when application current measurement requirements do not exceed the substitute part's rated capacity. HAL 200-S substitutes for applications requiring maximum 200A sensing. HAL 50-S substitutes for applications requiring maximum 50A sensing. Electrical interface, mounting, and compliance characteristics remain identical across all three parts.

Q: What is the primary difference between HAL 300-S, HAL 200-S, and HAL 50-S?

A: The sole difference is current sensing range. HAL 300-S measures 300A maximum, HAL 200-S measures 200A maximum, and HAL 50-S measures 50A maximum. All other parameters including sensor type, output voltage, frequency response, accuracy, supply voltage, response time, operating temperature, polarization, mounting type, and compliance status remain identical.

Q: Are all three parts pin-compatible and mechanically interchangeable?

A: Yes. HAL 300-S, HAL 200-S, and HAL 50-S share identical mounting type (Chassis Mount), package type (Module), and electrical interface specifications. Mechanical and electrical interchangeability is confirmed across all three parts.

Q: Do substitutions affect frequency response or measurement accuracy?

A: No. All three parts maintain identical frequency response (DC ~ 50kHz), accuracy (±1%), and linearity (±0.5%). Substitution does not alter measurement performance characteristics.

Q: What compliance certifications apply to substitute parts?

A: HAL 200-S and HAL 50-S maintain identical RoHS compliance status and REACH unaffected designation as the HAL 300-S. No compliance variations exist between the three parts.

Q: Can HAL 300-S substitute for HAL 200-S or HAL 50-S?

A: No. Substitution direction is unidirectional. HAL 300-S cannot substitute for lower-rated parts. Only lower current-sensing models (HAL 200-S, HAL 50-S) substitute for HAL 300-S when application requirements permit reduced sensing capacity.
