HY 12-P Current Sensor Hall Effect Equivalent & Substitute Parts

Part Overview

The HY 12-P is a Hall Effect open loop current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 12.5A sensing range. This component is classified as "Not For New Designs," indicating it has reached end-of-life status in the manufacturer's product portfolio. Organizations currently using HY 12-P components in active applications require documented equivalent and substitute parts to ensure supply chain continuity and support ongoing production requirements.

Substitute Part Grouping Explanation

Substitute parts for the HY 12-P are identified within the LEM USA Inc. HY series based on compatibility across the following critical parameters:

Preserved Parameters (Must Match for Substitution):

• Sensor Type: Hall Effect, Open Loop
• Measurement Type: AC/DC
• Number of Channels: 1
• Output Type: Ratiometric, Voltage
• Frequency Range: DC ~ 50kHz
• Linearity: ±1%
• Accuracy: ±1%
• Supply Voltage: ±12V ~ 15V
• Response Time: 3µs
• Maximum Supply Current: 10mA
• Operating Temperature Range: -10°C ~ 80°C
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package Type: Module
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

Variable Parameter (Determines Substitution Applicability):

• Current Sensing Range: 12.5A (main part), 10A (HY 10-P), 5A (HY 5-P)

The HY 10-P and HY 5-P are parametric equivalents within the HY series. Selection between these substitutes depends on the specific current measurement requirements of the application circuit. Lower current-rated sensors (HY 10-P, HY 5-P) may be used in applications where the maximum current does not exceed their respective sensing ranges.

Parameter Comparison

Engineering Selection Recommendations

HY 12-P Primary Application Scope: The HY 12-P is designated "Not For New Designs" by the manufacturer. This status indicates the part is no longer recommended for incorporation into new product development. Existing applications currently utilizing HY 12-P components require substitution planning for long-term supply assurance.

Substitution Criteria:

The HY 10-P and HY 5-P are direct parametric equivalents to the HY 12-P across all electrical, mechanical, and compliance specifications except for current sensing range. Both substitute parts maintain identical performance characteristics in frequency response, accuracy, linearity, response time, supply voltage requirements, and operating temperature range.

Selection Logic:

• HY 10-P: Use when application maximum current requirement does not exceed 10A. This part provides the closest current sensing range to the HY 12-P while maintaining all other electrical and mechanical parameters.

• HY 5-P: Use when application maximum current requirement does not exceed 5A. This part is suitable for lower current measurement applications within the HY series.

Compliance Assurance:

All three parts (HY 12-P, HY 10-P, HY 5-P) carry identical RoHS Compliance status, REACH Unaffected designation, and Moisture Sensitivity Level 1 (Unlimited) rating. Substitution does not introduce compliance risk for regulated applications.

Frequently Asked Questions (FAQ)

Q: Can HY 10-P or HY 5-P be used as direct replacements for HY 12-P in existing circuit designs?

A: HY 10-P and HY 5-P are parametric equivalents to HY 12-P across all electrical and mechanical specifications except current sensing range. Substitution is valid only if the application's maximum current requirement does not exceed the substitute part's rated sensing range (10A for HY 10-P, 5A for HY 5-P). No circuit modifications are required for parts with compatible current ratings.

Q: What is the primary difference between HY 12-P, HY 10-P, and HY 5-P?

A: The sole difference between these three parts is the current sensing range: HY 12-P measures up to 12.5A, HY 10-P measures up to 10A, and HY 5-P measures up to 5A. All other parameters—sensor type, output characteristics, frequency response, accuracy, linearity, supply voltage, response time, operating temperature, and compliance certifications—are identical.

Q: Are there any package or mounting differences between HY 12-P and its substitutes?

A: No. HY 12-P, HY 10-P, and HY 5-P share identical mounting type (Through Hole), package type (Module), and packaging format (Tray). Direct physical substitution is possible without PCB redesign.

Q: Why is HY 12-P marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and promotion of this part for new applications. Existing designs using HY 12-P should transition to substitute parts (HY 10-P or HY 5-P) to ensure long-term supply availability and manufacturer support.

Q: Do HY 10-P and HY 5-P have the same RoHS and REACH compliance status as HY 12-P?

A: Yes. All three parts carry RoHS Compliant status and REACH Unaffected designation. Substitution does not alter compliance posture for regulated applications.

Q: What is the inventory status of substitute parts?

A: HY 10-P has 1527 pieces in stock, and HY 5-P has 866 pieces in stock, both in new original condition. Inventory availability should be verified at time of procurement.
