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

Part Overview

The LES 6-NP is an active Hall Effect current sensor manufactured by LEM USA Inc., designed for bidirectional AC/DC current measurement applications. This closed-loop module provides ratiometric voltage output with 6A sensing capability and operates across industrial temperature ranges. The part is currently in active production status with full RoHS compliance and REACH unaffected classification. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and supply chain availability require alternative sourcing options while maintaining system functionality.

Key Parameters

Substitute Part Grouping Explanation

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

Electrical Performance Criteria:

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

Mechanical & Compliance Criteria:

• Mounting type: Through Hole
• Package type: Module
• RoHS compliance: Required
• REACH status: Unaffected classification

Acceptable Variance:

• Accuracy specification may differ (±2.25% for LES 6-NP versus ±1.25% for LXSR 6-NPS), as improved accuracy does not compromise system compatibility
• Linearity remains constant at ±0.1% across all qualified substitutes

The LXSR 6-NPS qualifies as a parametric equivalent substitute based on complete electrical and mechanical alignment with these criteria.

Engineering Selection Recommendations

LES 6-NP Selection Criteria: The LES 6-NP remains the primary choice for applications where the specified ±2.25% accuracy tolerance is acceptable and where existing inventory or established supply relationships favor this part number. Both the LES 6-NP and LXSR 6-NPS maintain active production status with full regulatory compliance.

LXSR 6-NPS Selection Criteria: The LXSR 6-NPS provides improved accuracy specification at ±1.25%, representing a 44% reduction in maximum accuracy error compared to the LES 6-NP. This substitute is appropriate for applications requiring tighter measurement tolerance while maintaining all other electrical and mechanical specifications. The LXSR 6-NPS is currently available with higher inventory levels (1657 pcs versus 927 pcs for LES 6-NP).

Compliance & Regulatory: Both parts maintain identical RoHS compliance status and REACH unaffected classification, ensuring equivalent regulatory standing for industrial and commercial applications. Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related handling restrictions.

Supply Chain Considerations: Selection between these parts may be influenced by inventory availability, lead time requirements, and cost structure. Both parts are manufactured by LEM USA Inc. and are classified as active products with ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can the LXSR 6-NPS be used as a direct replacement for the LES 6-NP in existing designs?

A: Yes. The LXSR 6-NPS is electrically and mechanically equivalent to the LES 6-NP across all critical parameters including current sensing range, output type, sensitivity, frequency response, supply voltage, response time, operating temperature, and mounting configuration. The improved accuracy specification of the LXSR 6-NPS does not create compatibility issues with existing circuit designs.

Q: What is the primary difference between these two parts?

A: The primary difference is accuracy specification. The LES 6-NP specifies ±2.25% accuracy, while the LXSR 6-NPS specifies ±1.25% accuracy. All other electrical and mechanical parameters are identical. The LXSR 6-NPS represents an improved performance variant within the same functional category.

Q: Are there any differences in packaging or mounting between these parts?

A: No. Both parts use identical Through Hole mounting type and Module package configuration. No PCB layout modifications are required when substituting between these parts.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the LES 6-NP and LXSR 6-NPS are RoHS Compliant and REACH Unaffected. Both carry identical Moisture Sensitivity Level 1 (Unlimited) classification. No additional compliance considerations apply to either part.

Q: Which part should be selected for new designs?

A: For new designs, the LXSR 6-NPS is the recommended choice due to superior accuracy specification (±1.25% versus ±2.25%) and higher current inventory availability. However, either part is technically suitable if the LES 6-NP accuracy specification meets application requirements.

Q: Are there any temperature or frequency response differences?

A: No. Both parts operate across the identical temperature range (-40°C to 105°C) and frequency response (300 kHz). No performance differences exist in these parameters.

Q: Can these parts be used interchangeably in mid-production?

A: Yes. The electrical equivalence and identical mechanical specifications allow mid-production substitution without circuit redesign or PCB modification. However, design documentation should be updated to reflect the part number change.
