HAIS 150-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HAIS 150-P is a Hall Effect open loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications up to 150A. This component is classified as "Not For New Designs," indicating it has reached end-of-life status in the manufacturer's product portfolio. For ongoing production requirements or new design implementations, equivalent substitute parts within the HAIS series provide functional alternatives with reduced current-sensing ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the HAIS series is determined by the following critical parameters that remain constant across all equivalent parts:

Fixed Parameters (Identical Across All Variants):

• Sensor Type: Hall Effect, Open Loop
• Output Type: Ratiometric, Voltage
• Frequency Range: DC ~ 50kHz
• Linearity: ±0.5%
• Accuracy: ±1%
• Supply Voltage: 5V
• Response Time: 5µs
• Maximum Supply Current: 19mA
• Operating Temperature Range: -40°C ~ 85°C
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package Type: Module
• Packaging Format: Tray
• Compliance: RoHS Compliant, REACH Unaffected

Variable Parameter (Determines Substitution Eligibility):

• Current - Sensing Rating: 150A (main part), 100A (HAIS 100-P, HAIS 100-TP), 50A (HAIS 50-P, HAIS 50-TP)

Substitute parts are valid only when the application's maximum current requirement does not exceed the substitute part's current-sensing rating. The HAIS 150-P can be substituted by HAIS 100-P, HAIS 100-TP, HAIS 50-P, or HAIS 50-TP only in applications requiring 100A or 50A maximum current measurement, respectively.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: All parts in this substitution group, including the HAIS 150-P, carry "Not For New Designs" status. This designation indicates the manufacturer has discontinued active development and support for this product line. For new design implementations, alternative current sensor solutions outside the HAIS series should be evaluated.

Compliance and Certification: All substitute parts maintain identical RoHS Compliance and REACH Unaffected status, ensuring regulatory equivalence for applications subject to these standards. No compliance barriers exist between the main part and substitute options.

Current Rating Selection: Selection among HAIS 100-P, HAIS 100-TP, HAIS 50-P, and HAIS 50-TP must be based strictly on the maximum continuous current the application requires. A substitute part with a current-sensing rating lower than the application's peak current will operate outside its specified accuracy and linearity parameters.

Packaging Equivalence: HAIS 100-P and HAIS 100-TP are functionally equivalent except for packaging designation. Similarly, HAIS 50-P and HAIS 50-TP differ only in packaging format. Both variants within each current rating are suitable for through-hole mounting applications with tray packaging.

Frequently Asked Questions (FAQ)

Q: Can HAIS 100-P substitute for HAIS 150-P in all applications?

A: No. HAIS 100-P is suitable only for applications where the maximum current measurement requirement does not exceed 100A. Applications requiring measurement of currents above 100A must use HAIS 150-P or a higher-rated alternative.

Q: What is the difference between HAIS 100-P and HAIS 100-TP?

A: Both parts have identical electrical specifications and current-sensing ratings of 100A. The designation difference (P vs. TP) relates to packaging format, but both are supplied in tray packaging. They are interchangeable for circuit design purposes.

Q: Are HAIS 50-P and HAIS 50-TP interchangeable?

A: Yes. Both parts are functionally equivalent with 50A current-sensing ratings and identical electrical characteristics. The packaging designation does not affect circuit performance or compatibility.

Q: If my application uses 75A maximum current, which substitute should I select?

A: HAIS 100-P or HAIS 100-TP must be used, as they have a 100A rating that accommodates the 75A requirement. HAIS 50-P and HAIS 50-TP are not suitable because their 50A rating is below the application's maximum current.

Q: Do all HAIS series parts have the same response time and frequency range?

A: Yes. All parts in this substitution group maintain 5µs response time and DC ~ 50kHz frequency range. These parameters are constant across all current ratings.

Q: What is the significance of "Not For New Designs" status?

A: This status indicates the manufacturer has discontinued active support and development for this product line. While existing inventory remains available, new design implementations should evaluate alternative current sensor solutions from active product lines.

Q: Are there any temperature or supply voltage differences between substitute parts?

A: No. All substitute parts operate identically across -40°C to 85°C temperature range and require 5V supply voltage. Operating conditions are uniform across all current ratings.

Q: Can I use HAIS 50-P in place of HAIS 150-P?

A: Only if your application's maximum current requirement does not exceed 50A. Using HAIS 50-P in an application requiring higher current measurement will result in sensor saturation and loss of measurement accuracy.
