HAIS 100-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HAIS 100-P is a Hall Effect open-loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications up to 100A. This module provides ratiometric voltage output with ±1% accuracy and operates across a temperature range of -40°C to 85°C.

The HAIS 100-P carries a "Not For New Designs" product status designation. This status necessitates identification of equivalent and substitute parts for applications requiring active component sourcing, design continuity, or long-term availability assurance.

Substitute Part Grouping Explanation

Substitution eligibility for the HAIS 100-P is determined by strict parameter matching across the following critical specifications:

Primary Substitution Criteria (Must Match Exactly):

• Sensor Type: Hall Effect, Open Loop
• For Measuring: AC/DC
• Number of Channels: 1
• Output Type: Ratiometric, Voltage
• Voltage - Supply: 5V
• Frequency Range: DC ~ 50kHz
• Linearity: ±0.5%
• Accuracy: ±1%
• Response Time: 5µs
• Current - Supply (Max): 19mA
• Operating Temperature: -40°C ~ 85°C
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package / Case: Module
• RoHS Status: RoHS Compliant
• REACH Status: REACH Unaffected

Secondary Substitution Criteria (Current Rating Dependent):

• Current - Sensing: 100A (primary specification) or 50A (reduced capacity variant)

The HAIS 100-P has two direct parametric equivalents at the 100A rating and two variants at the 50A rating. All four parts share identical electrical and mechanical specifications except for current-sensing capacity.

Parameter Comparison

Engineering Selection Recommendations

100A Current Rating Substitutes:

HAIS 100-TP is a direct parametric equivalent to HAIS 100-P. Both parts maintain identical electrical and mechanical specifications. Selection between these two 100A variants depends on application-specific requirements and inventory availability. Current inventory shows 1388 units of HAIS 100-P and 1039 units of HAIS 100-TP in stock.

50A Current Rating Variants:

HAIS 50-P and HAIS 50-TP are parametric equivalents to each other at the 50A current-sensing rating. These parts are suitable for applications where the maximum current measurement requirement does not exceed 50A. All other electrical and mechanical parameters remain identical to the 100A variants. Current inventory shows 1393 units of HAIS 50-P and 745 units of HAIS 50-TP in stock.

Compliance and Regulatory Status:

All four substitute parts carry identical RoHS Compliant and REACH Unaffected designations. All parts are classified under ECCN EAR99 and HTSUS 9030.33.3800. All parts maintain "Not For New Designs" product status, indicating that none of these components are recommended for new design implementations.

Frequently Asked Questions (FAQ)

Q: Can HAIS 100-P be directly replaced with HAIS 100-TP?

A: Yes. HAIS 100-TP is a direct parametric equivalent with identical electrical and mechanical specifications. Both parts are 100A Hall Effect open-loop current sensors with 5V supply, ±1% accuracy, and through-hole mounting. Selection depends on availability and application requirements.

Q: Can HAIS 100-P be substituted with HAIS 50-P or HAIS 50-TP?

A: Substitution is possible only if the application's maximum current measurement requirement does not exceed 50A. The HAIS 50-P and HAIS 50-TP maintain all electrical and mechanical specifications identical to the 100A variants except for current-sensing capacity. Using a 50A sensor in a 100A application will result in signal saturation and measurement error.

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

A: Both parts are parametric equivalents with identical specifications. The designation difference (P versus TP) reflects packaging or internal configuration variations not specified in the provided parameters. Both are supplied in tray packaging and maintain identical electrical performance.

Q: Are all substitute parts RoHS compliant?

A: Yes. HAIS 100-P, HAIS 100-TP, HAIS 50-P, and HAIS 50-TP are all RoHS Compliant and REACH Unaffected.

Q: What is the operating temperature range for all substitute parts?

A: All four parts operate across -40°C to 85°C. This specification is identical across HAIS 100-P, HAIS 100-TP, HAIS 50-P, and HAIS 50-TP.

Q: Can these sensors measure both AC and DC current?

A: Yes. All four parts are rated for AC/DC current measurement with frequency response from DC to 50kHz. Bidirectional polarization enables measurement of current flow in both directions.

Q: What is the response time for these sensors?

A: All four parts have a response time of 5µs, enabling measurement of rapidly changing current signals within the DC to 50kHz frequency range.

Q: Are there inventory considerations when selecting a substitute?

A: Current inventory levels are: HAIS 100-P (1388 units), HAIS 100-TP (1039 units), HAIS 50-P (1393 units), and HAIS 50-TP (745 units). Availability may influence selection for high-volume applications.
