LPSR 25-NP KIT Current Sensor Hall Effect Equivalent & Substitute Parts

Part Overview

The LPSR 25-NP KIT is a 3-piece kit containing Hall Effect closed-loop current sensors manufactured by LEM USA Inc. This product is classified as Obsolete and has been superseded by active alternatives. The sensor is designed for AC/DC current measurement applications requiring bidirectional sensing capability with ratiometric voltage output. Due to its obsolete status, identifying functionally equivalent active production parts is essential for design continuity and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the LPSR 25-NP KIT is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute identified is the LPSR 25-NP, which maintains identical specifications across all critical parameters:

Substitution Criteria (All Must Match):

• Current sensing range: 25A
• Sensor technology: Hall Effect, Closed Loop
• Channel configuration: 1 Channel
• Output format: Ratiometric Voltage
• Sensitivity: 25mV/A
• Supply voltage range: 4.75V – 5.25V
• Accuracy: ±1.25%
• Linearity: ±0.1%
• Frequency response: 300kHz
• Response time: 400ns
• Operating temperature range: -40°C to +105°C
• Polarization: Bidirectional
• Mounting: Through Hole
• RoHS Status: RoHS Compliant

The LPSR 25-NP differs from the kit version only in packaging format (Tray vs. Kit configuration) and product status (Active vs. Obsolete). All functional and electrical parameters are identical, making it a direct functional equivalent.

Engineering Selection Recommendations

Primary Substitute: LPSR 25-NP

The LPSR 25-NP is the direct functional equivalent of the LPSR 25-NP KIT. Selection of this substitute is based on the following engineering factors:

1. Product Status Transition: The LPSR 25-NP KIT is classified as Obsolete, while the LPSR 25-NP maintains Active production status. This ensures long-term availability and supply chain continuity.

2. Electrical Equivalence: All electrical parameters—current range, sensitivity, accuracy, linearity, frequency response, and supply voltage—are identical between the kit and substitute versions.

3. Regulatory Compliance: Both parts maintain RoHS Compliant status and REACH Unaffected classification, satisfying regulatory requirements for new designs and procurement.

4. Packaging Consideration: The primary difference is packaging format. The kit version is supplied as a 3-piece set, while the substitute is supplied in Tray packaging. Procurement quantity requirements should account for this difference.

5. Mechanical Compatibility: Through-hole mounting type is preserved, ensuring PCB assembly compatibility without design modification.

For applications currently using the LPSR 25-NP KIT, direct substitution with the LPSR 25-NP is electrically and mechanically valid. No circuit redesign or signal conditioning modifications are required.

Frequently Asked Questions (FAQ)

Q: Can the LPSR 25-NP directly replace the LPSR 25-NP KIT in existing designs?

A: Yes. The LPSR 25-NP is electrically and mechanically equivalent to the LPSR 25-NP KIT. All functional parameters, including current range, sensitivity, accuracy, output format, and mounting type, are identical. No circuit modifications are required.

Q: What is the difference between the LPSR 25-NP KIT and LPSR 25-NP?

A: The primary difference is packaging format and product status. The LPSR 25-NP KIT is supplied as a 3-piece kit in obsolete status, while the LPSR 25-NP is supplied in Tray packaging with Active production status. Electrical and mechanical specifications are identical.

Q: Why is the LPSR 25-NP KIT classified as Obsolete?

A: The kit version has been superseded by the standard LPSR 25-NP module in Tray packaging. The Active substitute provides equivalent functionality with improved supply chain availability.

Q: Are there any compliance differences between the two parts?

A: No. Both the LPSR 25-NP KIT and LPSR 25-NP maintain identical RoHS Compliant status and REACH Unaffected classification.

Q: What quantity considerations apply when switching from the kit to the standard module?

A: The LPSR 25-NP KIT is supplied as a 3-piece set, while the LPSR 25-NP is supplied as individual modules in Tray packaging. Procurement quantities should be adjusted accordingly to account for this packaging difference.

Q: Is the through-hole mounting type preserved in the substitute?

A: Yes. Both the LPSR 25-NP KIT and LPSR 25-NP use through-hole mounting, ensuring compatibility with existing PCB designs without modification.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -40°C to +105°C (TA), suitable for industrial and extended-temperature applications.

Q: Are the sensitivity and output characteristics identical?

A: Yes. Both parts provide 25mV/A sensitivity with ratiometric voltage output, identical linearity (±0.1%), accuracy (±1.25%), and frequency response (300kHz).
