Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HAL 400-S are identified through parametric equivalence analysis. The critical substitution parameters are:

Identical Parameters (Required for Substitution):

• Sensor Technology: Hall Effect, Open Loop
• Measurement Type: AC/DC bidirectional
• Output Configuration: Voltage output
• Frequency Response: DC ~ 50kHz
• Linearity: ±0.5%
• Accuracy: ±1%
• Supply Voltage: ±15V
• Response Time: 3µs
• Operating Temperature Range: -25°C ~ 85°C
• Polarization: Bidirectional
• Mounting: Panel Mount
• Package: Module
• Compliance: RoHS Compliant, REACH Unaffected

Variable Parameter (Defines Substitution Scope):

• Current Sensing Capacity: 400A (main part) vs. 100A (substitute)

The HAL 100-S qualifies as a parametric equivalent substitute when application current requirements do not exceed 100A. All electrical characteristics, response behavior, and environmental specifications remain identical. The reduced current sensing range represents the only functional difference.

Engineering Selection Recommendations

HAL 400-S Selection Criteria: Select the HAL 400-S when application requirements specify current measurement up to 400A. This part maintains Active product status with full regulatory compliance (RoHS Compliant, REACH Unaffected, EAR99 classification). The module integrates directly into panel-mount installations with ±15V dual supply architecture.

HAL 100-S Substitution Criteria: The HAL 100-S functions as a direct substitute when measured current does not exceed 100A. All electrical performance metrics, response characteristics, and environmental operating parameters remain identical to the HAL 400-S. Both parts share identical supply voltage requirements, response time specifications, and accuracy ratings. Substitution is valid for applications where current sensing capacity of 100A satisfies design specifications. Both parts maintain Active status and identical compliance certifications.

Compliance & Regulatory Basis: Both parts carry RoHS Compliant designation and REACH Unaffected status, enabling use in regulated industrial and commercial applications. EAR99 export classification applies to both variants. Moisture Sensitivity Level 1 (Unlimited) indicates no moisture-related handling restrictions for either part.

Frequently Asked Questions (FAQ)

Q: Can HAL 100-S replace HAL 400-S in all applications?

A: The HAL 100-S functions as a direct substitute only when application current requirements do not exceed 100A. All electrical specifications, response times, accuracy ratings, and environmental operating ranges are identical. If the circuit measures currents above 100A, the HAL 100-S will not provide accurate readings and substitution is not valid.

Q: Are the supply voltage requirements identical between HAL 400-S and HAL 100-S?

A: Yes. Both parts require ±15V dual supply voltage with maximum supply current of 25mA. Power supply connections and voltage specifications are identical, enabling direct circuit compatibility.

Q: Do both parts have identical response time and frequency response?

A: Yes. Both HAL 400-S and HAL 100-S deliver 3µs response time and DC ~ 50kHz frequency response. Dynamic performance characteristics are identical across both variants.

Q: What is the accuracy specification for both parts?

A: Both parts maintain ±1% accuracy with ±0.5% linearity. Measurement precision and signal linearity are identical between HAL 400-S and HAL 100-S.

Q: Are there any differences in operating temperature ranges?

A: No. Both parts operate across -25°C ~ 85°C temperature range. Environmental operating specifications are identical.

Q: Can these parts be used interchangeably in panel-mount installations?

A: Yes, from a mechanical perspective. Both parts feature Panel Mount configuration with Module package type. Physical mounting compatibility is identical. However, current sensing capacity differences must be verified against application requirements.

Q: What is the difference between these two parts?

A: The HAL 100-S and HAL 400-S differ only in current sensing capacity. The HAL 100-S measures up to 100A, while the HAL 400-S measures up to 400A. All other electrical, mechanical, and environmental specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both HAL 400-S and HAL 100-S carry RoHS Compliant designation and REACH Unaffected status, meeting regulatory requirements for controlled substance content.
