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

Part Overview

The LESR 6-NP KIT is a 3-piece kit containing Hall Effect current sensors manufactured by LEM USA Inc. This closed-loop bidirectional current sensor module 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 alternatives essential for ongoing procurement and system maintenance. The LESR 6-NP represents the direct active substitute, offering identical electrical and mechanical specifications with current production status.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LESR 6-NP KIT is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Current sensing range (6A), sensor technology (Hall Effect, Closed Loop), output configuration (Ratiometric Voltage), sensitivity (104.2 mV/A), frequency response (300 kHz), linearity (±0.1%), accuracy (±1.25%), supply voltage window (4.75V to 5.25V), response time (400 ns), and maximum supply current (23 mA).

Thermal & Environmental Parameters: Operating temperature range (-40°C to 105°C), polarization (Bidirectional), and moisture sensitivity level (MSL 1).

Mechanical & Compliance Parameters: Mounting type (Through Hole), package type (Module), RoHS compliance, and REACH status.

The LESR 6-NP qualifies as a direct substitute because it maintains 100% electrical and mechanical parameter equivalence with the LESR 6-NP KIT, with the distinction that the kit version provides three units while the substitute is supplied individually.

Parameter Comparison

Engineering Selection Recommendations

The LESR 6-NP is the appropriate selection for applications currently using or requiring the LESR 6-NP KIT. The substitute part maintains full electrical and mechanical compatibility with identical performance characteristics across all specified parameters.

Product Status Consideration: The LESR 6-NP KIT is classified as obsolete, while the LESR 6-NP is active production. For new designs and ongoing procurement, the LESR 6-NP should be specified to ensure long-term supply chain continuity and manufacturer support.

Compliance & Certification: Both parts maintain identical RoHS compliance, REACH unaffected status, and EAR99 export classification. No additional compliance verification is required when transitioning between these parts.

Packaging Distinction: The primary difference between the two part numbers is packaging configuration. The LESR 6-NP KIT provides three sensor units, while the LESR 6-NP is supplied individually in tray packaging. Procurement quantities should be adjusted accordingly to meet application requirements.

Frequently Asked Questions (FAQ)

Q: Can the LESR 6-NP directly replace the LESR 6-NP KIT in existing applications?

A: Yes. The LESR 6-NP provides identical electrical performance and mechanical compatibility. The only distinction is that the kit version supplies three units while the substitute is individual. Adjust procurement quantities to account for this packaging difference.

Q: Are there any electrical parameter differences between these parts?

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

Q: What is the significance of the product status change from obsolete to active?

A: The LESR 6-NP KIT is no longer in production. The LESR 6-NP is the active equivalent manufactured by LEM USA Inc. For new designs and ongoing procurement, specify the LESR 6-NP to ensure availability and manufacturer support.

Q: Are thermal and environmental operating ranges identical?

A: Yes. Both parts operate across the same temperature range (-40°C to 105°C), maintain bidirectional polarization, and carry identical MSL 1 (Unlimited) moisture sensitivity ratings.

Q: Do these parts require different mounting or PCB layout considerations?

A: No. Both parts use through-hole mounting in module package configuration. PCB layout and mounting procedures remain unchanged.

Q: Are compliance certifications identical?

A: Yes. Both parts are RoHS compliant, REACH unaffected, and classified as EAR99 for export purposes. No additional compliance documentation is required.

Q: How should procurement quantities be adjusted when transitioning from the kit to the individual part?

A: The LESR 6-NP KIT contains three sensors. When specifying the LESR 6-NP as a substitute, multiply the kit quantity by three to obtain the equivalent number of individual sensors required.
