HMS 15-P Current Sensor Hall Effect Module - Equivalent & Substitute Parts

Part Overview

The HMS 15-P is a Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 15A sensing range. This surface-mount module operates as an open-loop, bidirectional sensor with ratiometric voltage output. The product is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design support and procurement planning. The HMS 15-P remains available in inventory (1049 pieces) and maintains full RoHS compliance and REACH unaffected status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HMS 15-P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Sensor Type: Hall Effect, Open Loop
• Output Type: Ratiometric, Voltage
• Supply Voltage: 5V
• Frequency Response: DC ~ 50kHz
• Linearity: ±0.5%
• Accuracy: ±1%
• Response Time: 5µs
• Maximum Supply Current: 19mA
• Operating Temperature Range: -40°C ~ 85°C
• Polarization: Bidirectional
• Mounting Type: Surface Mount
• Package Type: Module
• Compliance: RoHS Compliant, REACH Unaffected

Variable Parameter (Allows Substitution):

• Current Sensing Range: The HMS 15-P (15A) can be substituted with the HMS 10-P (10A) when the application current requirement does not exceed 10A. The HMS 10-P maintains all other electrical and mechanical specifications identically to the HMS 15-P.

The HMS 10-P is the only documented parametric equivalent within the HMS series for the HMS 15-P.

Engineering Selection Recommendations

HMS 10-P as Substitute for HMS 15-P:

The HMS 10-P is a valid parametric equivalent substitute for the HMS 15-P when the application current measurement requirement does not exceed 10A. Both components are obsolete products from the same HMS series manufactured by LEM USA Inc., with identical electrical performance characteristics, frequency response, accuracy specifications, and compliance certifications.

Selection Criteria:

1. Current Requirement Analysis: The HMS 10-P substitution is appropriate only when the maximum measured current in the application circuit remains at or below 10A. Applications requiring current measurement above 10A must retain the HMS 15-P or identify alternative current sensor solutions outside the HMS series.

2. Compliance and Certification: Both the HMS 15-P and HMS 10-P maintain identical RoHS compliance status and REACH unaffected classification, ensuring regulatory equivalence for applications subject to these standards.

3. Packaging Consideration: The HMS 15-P is supplied in Tape & Reel (TR) format, while the HMS 10-P is supplied in Cut Tape (CT) format. Procurement and assembly processes must account for this packaging difference.

4. Inventory Availability: The HMS 10-P maintains higher inventory availability (1278 pieces) compared to the HMS 15-P (1049 pieces), supporting long-term supply chain planning for obsolete product replacement.

5. Electrical Interface Compatibility: Both components operate on identical 5V supply voltage, produce ratiometric voltage output, and maintain identical response time and supply current specifications, ensuring direct circuit-level compatibility when current range requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can the HMS 10-P directly replace the HMS 15-P in all applications?

A: No. The HMS 10-P can replace the HMS 15-P only in applications where the maximum measured current does not exceed 10A. The HMS 10-P has a lower current sensing range (10A versus 15A). Applications requiring measurement of currents above 10A must use the HMS 15-P or alternative sensors with higher current ratings.

Q: Are the electrical output characteristics identical between HMS 15-P and HMS 10-P?

A: Yes. Both sensors produce ratiometric voltage output with identical accuracy (±1%), linearity (±0.5%), frequency response (DC ~ 50kHz), response time (5µs), and supply voltage requirements (5V). The only difference is the current sensing range.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated assembly equipment. Cut Tape (CT) packaging supplies components on tape segments cut to specific lengths, typically for manual assembly or smaller production runs. Both formats contain the same component; the difference is in delivery and handling format only.

Q: Are both HMS 15-P and HMS 10-P still in production?

A: No. Both components are classified as obsolete products. However, inventory remains available from current stock (HMS 15-P: 1049 pieces; HMS 10-P: 1278 pieces). For new designs, alternative current sensor solutions should be evaluated.

Q: Do HMS 15-P and HMS 10-P have identical temperature operating ranges?

A: Yes. Both sensors operate across the identical temperature range of -40°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: What does "bidirectional" polarization mean for these sensors?

A: Bidirectional polarization indicates that both the HMS 15-P and HMS 10-P can measure current flowing in either direction (positive or negative current flow). This capability is identical in both components.

Q: Are there any compliance differences between HMS 15-P and HMS 10-P?

A: No. Both components maintain identical RoHS compliance status and REACH unaffected classification. They are equivalent from a regulatory and environmental compliance perspective.

Q: What is the MSL (Moisture Sensitivity Level) rating, and is it the same for both parts?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. Both HMS 15-P and HMS 10-P share this identical MSL rating.
