LPSR 50-NP KIT Current Sensor Hall Effect Equivalent & Substitute Parts

Part Overview

The LPSR 50-NP KIT is a 3-piece kit containing Hall Effect current sensors manufactured by LEM USA Inc. This closed-loop bidirectional current sensor is designed for AC/DC current measurement applications with a 50A sensing range. The product is classified as Obsolete, making identification of equivalent and substitute parts essential for system maintenance, redesign, and procurement continuity. The kit packaging format distinguishes it from individual sensor units, requiring careful consideration when selecting replacements for production or field service applications.

Substitute Part Grouping Explanation

Substitution of the LPSR 50-NP KIT is determined by electrical and mechanical parameter equivalence within the LPSR series. The primary substitute identified is the LPSR 50-NP, which maintains identical electrical specifications across all critical parameters: 50A current sensing, 12.5mV/A sensitivity, ±0.1% linearity, ±1.25% accuracy, 300kHz frequency response, 400ns response time, and bidirectional Hall Effect closed-loop operation.

The key differentiator between the main part and its substitute is packaging format and product status. The LPSR 50-NP KIT is supplied as a 3-piece kit in an Obsolete status, while the LPSR 50-NP is an individual sensor unit supplied in Tray packaging with Active product status. Both components share identical electrical performance parameters, supply voltage requirements (4.75V ~ 5.25V), operating temperature range (-40°C ~ 105°C), and compliance certifications (RoHS Compliant, REACH Unaffected).

Substitution eligibility is based on the following criteria:

• Sensor Type: Hall Effect, Closed Loop
• Current Sensing Capacity: 50A
• Output Configuration: Ratiometric Voltage
• Sensitivity: 12.5mV/A
• Frequency Response: 300kHz
• Linearity Tolerance: ±0.1%
• Accuracy: ±1.25%
• Supply Voltage: 4.75V ~ 5.25V
• Response Time: 400ns
• Mounting: Through Hole
• Polarization: Bidirectional
• Compliance: RoHS Compliant, REACH Unaffected

Engineering Selection Recommendations

The LPSR 50-NP serves as the direct electrical and mechanical equivalent to the obsolete LPSR 50-NP KIT. Selection of the LPSR 50-NP is supported by the following engineering factors:

Product Status Transition: The LPSR 50-NP KIT is classified as Obsolete, while the LPSR 50-NP maintains Active status with LEM USA Inc. This status difference ensures continued availability, technical support, and supply chain reliability for new designs and field replacements.

Electrical Equivalence: All electrical parameters are identical between the two components, including current sensing capacity (50A), sensitivity (12.5mV/A), frequency response (300kHz), linearity (±0.1%), accuracy (±1.25%), and response time (400ns). This equivalence ensures direct functional compatibility in existing circuit designs without modification to signal conditioning or measurement algorithms.

Compliance and Certification: Both components maintain identical RoHS Compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications across all geographic markets.

Packaging Consideration: The primary difference is packaging format. The LPSR 50-NP KIT provides three sensor units in kit configuration, while the LPSR 50-NP is supplied as an individual unit in Tray packaging. For applications requiring multiple sensors, procurement of multiple LPSR 50-NP units achieves equivalent functionality to the kit format.

Thermal and Environmental Performance: Operating temperature range (-40°C ~ 105°C), supply voltage tolerance (4.75V ~ 5.25V), and moisture sensitivity level (MSL 1) are identical, confirming compatibility across all specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the LPSR 50-NP directly replace the LPSR 50-NP KIT in existing applications?

A: Yes. The LPSR 50-NP provides identical electrical performance across all specified parameters. The primary consideration is packaging: the kit contains three sensors, while the LPSR 50-NP is a single unit. For applications using one sensor from the kit, a single LPSR 50-NP unit is the direct replacement. For applications using multiple kit sensors, multiple LPSR 50-NP units must be procured.

Q: What are the critical parameters that define substitution eligibility for the LPSR 50-NP KIT?

A: Substitution is determined by equivalence in the following parameters: 50A current sensing capacity, Hall Effect closed-loop sensor type, 12.5mV/A sensitivity, ±0.1% linearity, ±1.25% accuracy, 300kHz frequency response, 400ns response time, 4.75V ~ 5.25V supply voltage, bidirectional polarization, through-hole mounting, and module package type. All these parameters must match for functional equivalence.

Q: Why is the LPSR 50-NP KIT classified as Obsolete while the LPSR 50-NP is Active?

A: Product status reflects manufacturer lifecycle decisions. The kit packaging format may have been discontinued in favor of individual unit distribution. The LPSR 50-NP maintains Active status, ensuring ongoing availability and support. For new designs and field service, the LPSR 50-NP is the recommended selection.

Q: Are there any differences in RoHS or REACH compliance between the two parts?

A: No. Both the LPSR 50-NP KIT and LPSR 50-NP maintain identical RoHS Compliant status and REACH Unaffected status, satisfying all regulatory requirements for industrial applications.

Q: What is the moisture sensitivity level for these sensors?

A: Both components have a Moisture Sensitivity Level (MSL) of 1, indicating Unlimited moisture sensitivity. This classification means the components do not require special moisture control during storage or handling.

Q: Can the LPSR 50-NP be used in temperature-critical applications?

A: Yes. The LPSR 50-NP operates across the temperature range of -40°C ~ 105°C (TA), supporting both industrial and extended temperature applications. This range is identical to the LPSR 50-NP KIT.

Q: What is the supply current requirement for the LPSR 50-NP?

A: The maximum supply current is 51.3mA at the specified supply voltage range of 4.75V ~ 5.25V. This parameter is identical for both the kit and individual unit.

Q: Is the LPSR 50-NP suitable for AC and DC current measurement?

A: Yes. Both the LPSR 50-NP KIT and LPSR 50-NP are specified for AC/DC current measurement with bidirectional polarization, enabling measurement of current flow in both directions.
