LPSR 6-NP KIT Current Sensor Hall Effect Equivalent & Substitute Parts

Part Overview

The LPSR 6-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 6A sensing range and ratiometric voltage output. The main part is classified as obsolete, making identification of active equivalent parts essential for procurement and design continuity. The LPSR 6-NP represents the active production equivalent, offering identical electrical and mechanical specifications with improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPSR 6-NP KIT is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute relationship is based on the following criteria:

Electrical Parameter Equivalence:

• Current sensing range of 6A
• Hall Effect closed-loop sensor technology
• Single channel configuration
• Ratiometric voltage output with 104.2 mV/A sensitivity
• ±1.25% accuracy and ±0.1% linearity
• 4.75V to 5.25V supply voltage range
• 300 kHz frequency response and 400 ns response time

Mechanical Parameter Equivalence:

• Through-hole mounting type
• Module package configuration
• Bidirectional polarization capability

Compliance Equivalence:

• RoHS compliant status
• REACH unaffected classification
• EAR99 ECCN designation

The LPSR 6-NP (active production part) is the direct equivalent to the LPSR 6-NP KIT (obsolete kit version). Both parts share identical electrical specifications and mechanical characteristics. The primary difference is packaging: the kit contains three sensor units, while the LPSR 6-NP is supplied individually in tray packaging.

Engineering Selection Recommendations

Primary Recommendation: LPSR 6-NP

The LPSR 6-NP is the direct active production equivalent for the obsolete LPSR 6-NP KIT. Selection of this part is based on the following engineering criteria:

1. Product Status Alignment: The LPSR 6-NP maintains active production status, ensuring long-term availability and supply chain continuity. The kit version is obsolete and subject to discontinuation.

2. Electrical Specification Equivalence: All critical electrical parameters are identical, including current sensing range, output characteristics, accuracy, linearity, frequency response, and temperature operating range. No circuit redesign or recalibration is required.

3. Mechanical Compatibility: Through-hole mounting type and module package configuration are preserved, allowing direct PCB layout compatibility without modification.

4. Regulatory Compliance: Both parts maintain identical RoHS compliance, REACH unaffected status, and EAR99 ECCN classification, satisfying all regulatory requirements without additional documentation.

5. Packaging Consideration: The LPSR 6-NP is supplied individually in tray packaging. For applications requiring multiple units, order quantity should reflect the number of sensors needed. The kit packaging of the obsolete part is not a functional differentiator.

Procurement Strategy:

For designs currently using LPSR 6-NP KIT, transition to LPSR 6-NP by ordering individual units according to application requirements. No design changes, firmware updates, or testing protocols require modification. The parts are functionally and electrically interchangeable.

Frequently Asked Questions (FAQ)

Q1: Can LPSR 6-NP directly replace LPSR 6-NP KIT in existing designs?

A: Yes. The LPSR 6-NP is the active production equivalent with identical electrical and mechanical specifications. No circuit modifications, recalibration, or design changes are required. The only difference is packaging format: the kit contains three units, while LPSR 6-NP is supplied individually.

Q2: What is the difference between the kit and individual part packaging?

A: LPSR 6-NP KIT is an obsolete 3-piece kit configuration. LPSR 6-NP is the active equivalent supplied in tray packaging as individual units. Functionally and electrically, they are identical. Order the quantity of individual LPSR 6-NP parts needed for your application.

Q3: Are there any electrical parameter differences between the two parts?

A: No. Both parts share identical electrical specifications: 6A current sensing, 104.2 mV/A sensitivity, ±1.25% accuracy, ±0.1% linearity, 4.75V to 5.25V supply voltage, 300 kHz frequency response, and 400 ns response time.

Q4: Will LPSR 6-NP work with existing PCB layouts designed for LPSR 6-NP KIT?

A: Yes. Both parts use through-hole mounting in module package configuration. PCB layouts, footprints, and pin assignments are compatible without modification.

Q5: What compliance certifications apply to LPSR 6-NP?

A: LPSR 6-NP maintains RoHS compliance, REACH unaffected status, and EAR99 ECCN classification, identical to the obsolete kit version. All regulatory requirements are satisfied.

Q6: Is LPSR 6-NP available in the same quantity as the kit?

A: LPSR 6-NP is supplied individually in tray packaging. To obtain three units equivalent to the kit, order three LPSR 6-NP parts. Current inventory shows 1173 pieces in stock.

Q7: What is the operating temperature range for LPSR 6-NP?

A: The operating temperature range is -40°C to 105°C (TA), identical to the obsolete kit version. This range supports industrial and automotive applications.

Q8: Can LPSR 6-NP measure both AC and DC current?

A: Yes. LPSR 6-NP is rated for AC/DC current measurement with bidirectional polarization, allowing measurement of current flow in both directions.

Q9: What is the supply current requirement for LPSR 6-NP?

A: Maximum supply current is 23 mA at the specified 4.75V to 5.25V supply voltage range.

Q10: Is there a response time specification for LPSR 6-NP?

A: Yes. Response time is 400 ns, enabling fast transient current measurement and control loop applications requiring rapid signal acquisition.
