LKSR 6-NP Hall Effect Current Sensor - Equivalent & Substitute Parts

Part Overview

The LKSR 6-NP is a Hall Effect closed-loop current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications requiring 6A sensing capability. This sensor delivers ratiometric voltage output with bidirectional polarization and is housed in a through-hole module package. The product maintains active status with 777 units in current inventory stock.

Identification of equivalent and substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or specific application requirements while maintaining identical electrical and mechanical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LKSR 6-NP is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Current sensing capacity: 6A
• Sensor technology: Hall Effect, Closed Loop
• Output configuration: Ratiometric, Voltage
• Sensitivity: 104.2 mV/A
• Frequency response: 300 kHz
• Linearity tolerance: ±0.1%
• Accuracy specification: ±1.25%
• Supply voltage range: 4.75V ~ 5.25V
• Response time: 400 ns
• Maximum supply current: 23 mA
• Operating temperature range: -40°C ~ 105°C

Mechanical & Environmental Criteria:

• Mounting configuration: Through Hole
• Package classification: Module
• Polarization type: Bidirectional
• Number of channels: 1
• Measurement capability: AC/DC

Engineering Selection Recommendations

LXSR 6-NPS Substitution Validity:

The LXSR 6-NPS qualifies as a direct parametric equivalent to the LKSR 6-NP. All electrical performance specifications, mechanical characteristics, environmental ratings, and compliance certifications are identical across both part numbers.

Inventory Considerations:

Current stock availability shows 1657 units of LXSR 6-NPS compared to 777 units of LKSR 6-NP. Both parts maintain active product status with LEM USA Inc.

Compliance Status:

Both parts carry identical regulatory certifications: RoHS Compliant, REACH Unaffected, and EAR99 ECCN classification. Moisture sensitivity level 1 (Unlimited) applies to both variants, indicating no moisture sensitivity constraints during storage or handling.

Application Compatibility:

The LXSR 6-NPS operates within identical electrical parameters for AC/DC current measurement applications. Through-hole mounting configuration, module package type, and bidirectional polarization remain consistent. No circuit redesign or application modification is required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Can LXSR 6-NPS replace LKSR 6-NP in existing designs without modification?

A: Yes. All electrical specifications, mechanical dimensions, mounting configuration, and environmental operating ranges are identical. Direct substitution is possible without circuit or PCB layout changes.

Q: What determines whether a part qualifies as a substitute for LKSR 6-NP?

A: A substitute part must match all parameters across three categories: electrical performance (current range, sensitivity, accuracy, frequency response, supply voltage, response time), mechanical configuration (through-hole mounting, module package, bidirectional polarization), and environmental compliance (RoHS status, operating temperature range, moisture sensitivity level).

Q: Are there differences in packaging between LKSR 6-NP and LXSR 6-NPS?

A: Both parts are supplied in Tray packaging. Mounting type (Through Hole), package classification (Module), and all physical specifications remain identical.

Q: What is the significance of the series designation change from LKSR to LXSR?

A: The series designation change reflects a product line evolution within LEM USA Inc.'s current sensor portfolio. When all electrical and mechanical parameters remain identical, the series change does not affect substitution eligibility or application compatibility.

Q: Do both parts require identical supply voltage conditions?

A: Yes. Both LKSR 6-NP and LXSR 6-NPS require supply voltage within the range 4.75V ~ 5.25V. No supply circuit modifications are necessary when substituting between these parts.

Q: What is the maximum operating temperature for both sensors?

A: Both sensors operate across the temperature range -40°C ~ 105°C (TA). No thermal management changes are required when using either part number in the same application.

Q: Are both parts RoHS compliant?

A: Yes. Both LKSR 6-NP and LXSR 6-NPS carry RoHS Compliant status and are REACH Unaffected, meeting current environmental and regulatory requirements.
