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

Part Overview

The HAIS 50-P is a Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 50A sensing range. This component operates as an open-loop, bidirectional module with ratiometric voltage output, suitable for industrial and power management applications requiring galvanic isolation and fast response characteristics.

The HAIS 50-P carries a "Not For New Designs" product status designation. This classification indicates the part remains available for existing applications and maintenance requirements, but new circuit designs should evaluate current-generation alternatives. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and long-term project viability.

Substitute Part Grouping Explanation

Substitution eligibility for the HAIS 50-P is determined by strict parametric equivalence across all critical electrical and mechanical specifications. The following parameters establish the substitution criteria:

Critical Matching Parameters:

• Sensor Type: Hall Effect, Open Loop
• Current Sensing Range: 50A
• Number of Channels: 1
• Measurement Capability: AC/DC
• Output Configuration: Ratiometric, Voltage
• Frequency Response: 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
• Regulatory Compliance: RoHS Compliant, REACH Unaffected

Only parts matching all specified parameters across electrical performance, environmental ratings, and mechanical form factor qualify as direct substitutes. Packaging format (Tray) and series designation (HAIS) further define the substitution group.

Parameter Comparison

Engineering Selection Recommendations

The HAIS 50-TP qualifies as a parametric equivalent substitute for the HAIS 50-P based on complete electrical and mechanical specification alignment. Both components are manufactured by LEM USA Inc. within the HAIS series and maintain identical performance characteristics across all measured parameters.

Compliance and Regulatory Considerations: Both the HAIS 50-P and HAIS 50-TP carry RoHS Compliant certification and REACH Unaffected status, satisfying environmental and regulatory requirements for industrial applications in regulated markets.

Product Status Context: Both parts carry "Not For New Designs" designation. This status applies uniformly across the substitution group and does not differentiate between the two variants. For new circuit development, evaluation of current-generation Hall Effect current sensor offerings from LEM USA Inc. or alternative manufacturers is appropriate.

Supply Chain and Inventory: The HAIS 50-P maintains 1393 units in stock, while the HAIS 50-TP maintains 745 units in stock. Availability differences may influence component selection for immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: What is the functional difference between HAIS 50-P and HAIS 50-TP?

A: No functional difference exists between these parts. Both are Hall Effect current sensors with identical electrical specifications, frequency response, accuracy, and operating characteristics. The designation suffix (-P versus -TP) reflects packaging or internal configuration variants that do not affect electrical performance or substitutability.

Q: Can HAIS 50-TP replace HAIS 50-P in existing circuit designs?

A: Yes. The HAIS 50-TP is a direct parametric equivalent. All electrical parameters, output characteristics, supply requirements, and environmental ratings are identical. Through-hole mounting compatibility is maintained.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts share identical pinout requirements, voltage supply specifications (5V), output type (ratiometric voltage), and mechanical mounting configuration (through-hole module). PCB layout and circuit integration remain unchanged.

Q: Why do both parts carry "Not For New Designs" status?

A: This designation indicates both the HAIS 50-P and HAIS 50-TP are mature products in their lifecycle phase. LEM USA Inc. maintains these parts for existing applications and field replacements. New circuit designs should evaluate current-generation sensor alternatives from the manufacturer's active product portfolio.

Q: What is the significance of the packaging designation "Tray"?

A: Tray packaging indicates the components are supplied in bulk format suitable for automated assembly processes. This packaging type does not affect electrical performance or substitutability between HAIS 50-P and HAIS 50-TP variants.

Q: How do the 50A current sensing specifications apply to AC and DC measurements?

A: The HAIS 50-P and HAIS 50-TP support bidirectional measurement of both AC and DC currents up to 50A. The open-loop Hall Effect topology provides galvanic isolation and operates across the DC to 50kHz frequency range, accommodating both steady-state DC measurements and AC waveforms within this bandwidth.

Q: What response time performance should be expected in practical applications?

A: Both parts specify 5µs response time, enabling detection of rapid current transients and dynamic load changes. This performance level supports applications requiring fast feedback control and protection circuit triggering.
