HO 250-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HO 250-P is an active Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications requiring bidirectional sensing capability. This single-channel, open-loop module operates across a 250A sensing range with ratiometric voltage output and is housed in a through-hole mountable module package. The product maintains Active status with full RoHS compliance and REACH unaffected classification. Substitute parts are identified within the HO-P series to address application requirements where alternative current-sensing ranges are specified or inventory constraints necessitate component alternatives.

Substitute Part Grouping Explanation

Substitute parts within the HO-P series are identified based on strict parametric equivalence across all electrical and mechanical characteristics except for the current-sensing range specification. The HO 250-P accepts substitution with HO 180-P and HO 120-P under the following conditions:

Substitution Criteria (All Must Match):

• Sensor Type: Hall Effect, Open Loop
• Measurement Capability: AC/DC Bidirectional
• Number of Channels: 1
• Output Configuration: Ratiometric, Voltage (Selectable)
• Frequency Response: DC ~ 100kHz
• Linearity: ±0.5%
• Accuracy: ±1%
• Supply Voltage: 5V
• Response Time: 3.5µs
• Maximum Supply Current: 25mA
• Operating Temperature Range: -40°C ~ 105°C
• Mounting Type: Through Hole
• Package Type: Module, Single Pass Through
• Packaging Format: Tray
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99
• HTSUS: 9030.33.3800

Variable Parameter:

• Current Sensing Range: 250A (HO 250-P), 180A (HO 180-P), 120A (HO 120-P)

Substitution is valid only when the application's maximum current requirement does not exceed the substitute part's rated sensing range.

Parameter Comparison

Engineering Selection Recommendations

Component selection from the HO-P series substitutes is determined by application current requirements and regulatory compliance status. All three parts—HO 250-P, HO 180-P, and HO 120-P—maintain Active product status with identical RoHS compliance and REACH unaffected classification, ensuring regulatory equivalence across the series.

Selection Logic:

1. HO 250-P is the primary selection for applications requiring measurement of currents up to 250A.

2. HO 180-P is a valid substitute when application maximum current does not exceed 180A. This part provides equivalent electrical performance and identical compliance certifications.

3. HO 120-P is a valid substitute when application maximum current does not exceed 120A. This part provides equivalent electrical performance and identical compliance certifications.

All parts share identical electrical characteristics: 5V supply voltage, 3.5µs response time, ±0.5% linearity, ±1% accuracy, and DC to 100kHz frequency response. Through-hole mounting, single-channel configuration, and ratiometric voltage output remain constant across all three variants. Substitution is valid only when the substitute part's current-sensing range meets or exceeds the application's maximum current requirement.

Frequently Asked Questions (FAQ)

Q: Can HO 120-P replace HO 250-P in all applications?

A: No. HO 120-P is a valid substitute only when the application's maximum current requirement does not exceed 120A. If the application requires measurement of currents between 120A and 250A, HO 120-P is not suitable.

Q: Are there electrical performance differences between HO 250-P, HO 180-P, and HO 120-P?

A: No. All three parts share identical electrical specifications: 5V supply voltage, 3.5µs response time, ±0.5% linearity, ±1% accuracy, DC to 100kHz frequency response, and 25mA maximum supply current. The only difference is the current-sensing range.

Q: Do all three parts have the same mounting and packaging specifications?

A: Yes. HO 250-P, HO 180-P, and HO 120-P are all through-hole mounted, single-channel modules in tray packaging with identical physical package type (Module, Single Pass Through).

Q: Are all three parts RoHS compliant?

A: Yes. HO 250-P, HO 180-P, and HO 120-P are all RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: What is the frequency response capability of these sensors?

A: All three parts operate across DC to 100kHz frequency range, enabling measurement of both DC and AC currents within this bandwidth.

Q: Can these sensors measure bidirectional current?

A: Yes. All three parts are configured for bidirectional AC/DC measurement, allowing detection of current flow in both directions.

Q: What supply voltage is required for operation?

A: All three parts require a 5V supply voltage with maximum supply current of 25mA.

Q: What is the operating temperature range for these sensors?

A: All three parts operate across -40°C to 105°C temperature range.
