HX 15-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HX 15-P is a Hall Effect open loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 15A sensing range. This component features ratiometric voltage output, 1-channel configuration, and through-hole mounting in module form factor.

The HX 15-P carries a "Not For New Designs" product status designation. This status indicates the part is in mature or end-of-life phase. Identifying equivalent and substitute parts ensures design flexibility, supply chain continuity, and long-term project viability when the primary part becomes unavailable or when alternative current ratings are required for system optimization.

Substitute Part Grouping Explanation

Substitute parts for the HX 15-P are selected from the LEM USA Inc. HX series based on strict parametric equivalence. All substitute parts maintain identical electrical and mechanical characteristics with the exception of current sensing range, which is the primary differentiating parameter within this product family.

Substitution Criteria (Invariant Parameters):

• Sensor Type: Hall Effect, Open Loop
• Number of Channels: 1
• Output Type: Ratiometric, Voltage
• Measurement Type: AC/DC
• Frequency Response: 50kHz
• Linearity: ±1%
• Accuracy: ±1%
• Supply Voltage: ±15V
• Response Time: 3µs
• Maximum Supply Current: 15mA
• Operating Temperature Range: -25°C to 85°C
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package Type: Module
• RoHS Compliance: RoHS Compliant
• REACH Status: REACH Unaffected

Variable Parameter (Substitution Basis):

• Current Sensing Range: 3A, 5A, 10A, or 15A

Substitute parts are applicable when system requirements permit operation with lower current sensing ranges than the primary HX 15-P specification.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed—HX 03-P, HX 05-P, and HX 10-P—maintain full parametric equivalence to the HX 15-P across all electrical performance metrics, mechanical form factor, and regulatory compliance attributes. Selection among these parts is determined exclusively by application current measurement requirements.

Selection Logic:

• HX 03-P (3A): Select when system maximum current does not exceed 3A. Provides optimal measurement resolution for low-current applications.

• HX 05-P (5A): Select when system maximum current does not exceed 5A. Suitable for mid-range current measurement applications.

• HX 10-P (10A): Select when system maximum current does not exceed 10A. Bridges the gap between lower and higher current sensing requirements.

• HX 15-P (15A): Primary specification for systems requiring full 15A measurement capability.

All parts carry identical RoHS Compliant and REACH Unaffected certifications, ensuring regulatory compliance across all substitution scenarios. All parts maintain "Not For New Designs" status, indicating mature product lifecycle phase across the entire HX series family.

Frequently Asked Questions (FAQ)

Q: Can HX 03-P, HX 05-P, or HX 10-P be used as direct replacements for HX 15-P in existing designs?

A: Direct replacement is possible only if the application's maximum current requirement does not exceed the substitute part's sensing range. The substitute part must be capable of measuring the full current range present in the circuit. If circuit current can reach 15A, only HX 15-P provides adequate measurement capability.

Q: What is the primary difference between HX 15-P and its substitute parts?

A: The sole differentiating parameter is current sensing range. HX 15-P measures up to 15A, while HX 03-P, HX 05-P, and HX 10-P measure up to 3A, 5A, and 10A respectively. All other electrical characteristics, output type, frequency response, accuracy, and mechanical specifications are identical.

Q: Are all substitute parts available in the same packaging format?

A: Yes. HX 03-P, HX 05-P, HX 10-P, and HX 15-P are all supplied in Tray packaging format with identical through-hole module mounting configuration.

Q: Do substitute parts require circuit design modifications?

A: No circuit design modifications are required. All substitute parts feature identical supply voltage (±15V), output type (ratiometric voltage), response time (3µs), and pin configuration within the module package. Substitution is a direct component swap provided current range requirements are satisfied.

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

A: This designation indicates all parts in the HX series are in mature lifecycle phase. While fully functional and available, these parts are not recommended for new design implementations. Existing designs using these parts may continue to source replacements from available inventory.

Q: Can lower-rated substitute parts be used in applications where HX 15-P was originally specified?

A: Substitution with lower-rated parts is only valid if the actual circuit current never exceeds the substitute part's maximum sensing range. Exceeding the rated current range results in measurement saturation and loss of signal accuracy. System current analysis must confirm maximum operating current remains below the substitute part specification.

Q: Are there any performance differences in frequency response or accuracy between HX 15-P and substitute parts?

A: No. All parts maintain identical 50kHz frequency response, ±1% linearity, and ±1% accuracy specifications. Performance differences are limited to current sensing range only.
