HX 05-P Current Sensor Hall Effect 5A AC/DC Equivalent & Substitute Parts

Part Overview

The HX 05-P is a Hall Effect open loop current sensor manufactured by LEM USA Inc., designed for bidirectional AC/DC current measurement applications with a 5A sensing range. This component features ratiometric voltage output, ±15V dual supply operation, and through-hole module packaging. The product carries a "Not For New Designs" status, indicating that while functional and available in inventory, alternative solutions should be evaluated for new development projects. Identifying equivalent and substitute parts is necessary to ensure design continuity, manage supply chain risk, and maintain performance specifications across production lifecycles.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HX 05-P is determined by the following critical parameters:

Primary Substitution Criteria:

• Sensor Type: Hall Effect, Open Loop
• Current Sensing Range: 5A nominal
• Output Configuration: Ratiometric, Voltage
• Supply Voltage: ±15V
• Number of Channels: 1
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package Type: Module

Secondary Compatibility Parameters:

• Frequency Response: Minimum 50kHz
• Linearity: ±1% or better
• Response Time: 5µs or faster
• Operating Temperature: Must encompass -25°C to 85°C range
• Supply Current: 15mA maximum

Substitute parts are classified into two categories:

Parametric Equivalent (HX 03-P): Shares identical electrical architecture, supply requirements, output characteristics, and mounting specifications. Differs only in current sensing range (3A vs. 5A), making it suitable for applications with lower current measurement requirements while maintaining full electrical and mechanical compatibility.

Similar Manufacturer Part (L18P005D15): Matches the 5A current sensing range and core Hall Effect open loop architecture. Maintains identical supply voltage, output type, and bidirectional polarization. Differs in frequency response (DC to 100kHz vs. 50kHz), response time (5µs vs. 3µs), and operating temperature lower limit (-30°C vs. -25°C). Product status is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

HX 03-P Selection Criteria:

The HX 03-P is a direct parametric equivalent when the application current measurement requirement does not exceed 3A. Both parts share identical electrical specifications, supply architecture, response characteristics, and operating temperature range. Both components carry "Not For New Designs" status from LEM USA Inc., indicating equivalent lifecycle positioning. The HX 03-P maintains full RoHS compliance and identical mechanical mounting compatibility. Selection of HX 03-P is appropriate for applications where the 3A sensing range satisfies the measurement requirement, as it provides equivalent performance with lower current capacity.

L18P005D15 Selection Criteria:

The L18P005D15 from Tamura provides a 5A current sensing match to the HX 05-P and maintains core Hall Effect open loop architecture with identical supply voltage and output configuration. This part extends frequency response to 100kHz (compared to 50kHz) and operates across a wider lower temperature range (-30°C vs. -25°C). However, the L18P005D15 carries Obsolete product status and does not specify accuracy performance. Selection of L18P005D15 is limited to legacy system maintenance or applications where extended frequency response is required and product obsolescence is acceptable. RoHS compliance is maintained.

Compliance Considerations:

All three parts maintain RoHS compliance and are suitable for applications subject to RoHS directives. The HX 05-P and HX 03-P from LEM USA Inc. represent current product lines with "Not For New Designs" status, indicating available inventory and established supply chains. The L18P005D15 represents an obsolete alternative suitable only for replacement or legacy applications.

Frequently Asked Questions (FAQ)

Q: Can HX 03-P replace HX 05-P in all applications?

A: The HX 03-P can replace HX 05-P only when the application current measurement requirement does not exceed 3A. Both parts share identical electrical specifications, supply voltage, output type, response time, and operating temperature range. If the application requires measurement of currents above 3A, the HX 03-P will not provide adequate sensing range and HX 05-P must be retained.

Q: What are the key differences between HX 05-P and L18P005D15?

A: Both parts provide 5A current sensing with Hall Effect open loop architecture and ±15V supply operation. The L18P005D15 offers extended frequency response (DC to 100kHz vs. 50kHz) and wider lower temperature range (-30°C vs. -25°C). The L18P005D15 has a slower response time (5µs vs. 3µs) and does not specify accuracy performance. The L18P005D15 carries Obsolete product status, while HX 05-P is marked "Not For New Designs."

Q: Are all three parts mechanically compatible?

A: Yes. All three parts feature through-hole mounting type and module package configuration, ensuring mechanical compatibility in PCB layouts designed for the HX 05-P form factor.

Q: Which part should be selected for new designs?

A: The HX 05-P and HX 03-P both carry "Not For New Designs" status from LEM USA Inc., indicating that neither is recommended for new development. The L18P005D15 is Obsolete. For new designs, consultation with LEM USA Inc. for current-generation Hall Effect current sensor alternatives is necessary.

Q: Do all parts maintain RoHS compliance?

A: Yes. HX 05-P, HX 03-P, and L18P005D15 all maintain RoHS compliance status.

Q: What is the impact of response time differences between HX 05-P (3µs) and L18P005D15 (5µs)?

A: The 2µs difference in response time affects the speed at which the sensor detects and outputs changes in current. Applications requiring faster transient response or higher bandwidth signal processing should retain HX 05-P. Applications with slower current change rates can tolerate the L18P005D15 response time.
