HAW 05-P Current Sensor Hall Effect Equivalent & Substitute Parts

Part Overview

The HAW 05-P is a 5A Hall Effect open-loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications. This component features ratiometric voltage output, operates across DC to 50kHz frequency range, and is housed in an 8-DIP module package for through-hole mounting.

The HAW 05-P carries an Obsolete product status. Identifying equivalent and substitute parts is necessary for ongoing system support, design continuity, and procurement planning when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HAW 05-P is determined by strict alignment across the following critical parameters:

Primary Substitution Criteria:

• Current sensing rating: 5A
• Sensor technology: Hall Effect, Open Loop
• Measurement capability: AC/DC bidirectional
• Output configuration: Ratiometric voltage output
• Supply voltage: ±15V
• Number of channels: 1
• Mounting method: Through Hole
• Polarization: Bidirectional

Secondary Compatibility Factors:

• Frequency response capability (minimum DC ~ 50kHz)
• Linearity and accuracy specifications (±1%)
• Response time performance (3µs or faster)
• Operating temperature range overlap
• RoHS and regulatory compliance status

Parts meeting all primary criteria and maintaining compatibility across secondary factors are classified as direct substitutes. Parts with extended frequency response or improved temperature range are listed as compatible alternatives with noted parameter differences.

Engineering Selection Recommendations

HX 05-P (LEM USA Inc.) - Primary Substitute

The HX 05-P is the manufacturer-recommended substitute for the HAW 05-P. Both components are manufactured by LEM USA Inc. and share identical core specifications: 5A current sensing, Hall Effect open-loop technology, AC/DC measurement capability, ±15V supply, ±1% linearity and accuracy, and 3µs response time. The HX 05-P provides an extended operating temperature range (-25°C ~ 85°C versus -10°C ~ 75°C) and maintains RoHS compliance. The HX 05-P carries a "Not For New Designs" status, indicating it remains available for legacy system support and replacement applications. Maximum supply current is reduced to 15mA compared to 18mA in the HAW 05-P.

L18P005D15 (Tamura) - Compatible Alternative

The L18P005D15 is a cross-manufacturer substitute manufactured by Tamura. It maintains all primary substitution criteria: 5A current sensing, Hall Effect open-loop configuration, AC/DC bidirectional measurement, ±15V supply, ±1% linearity, and through-hole mounting. The L18P005D15 provides extended frequency response (DC ~ 100kHz versus DC ~ 50kHz) and broader operating temperature range (-30°C ~ 80°C). Response time is 5µs, which is 2µs slower than the HAW 05-P. Accuracy specification is not provided for this part. The L18P005D15 is RoHS compliant and carries Obsolete product status.

Selection Basis:

For direct replacement in existing designs requiring identical performance characteristics, the HX 05-P is the appropriate choice due to manufacturer continuity and equivalent specifications. The L18P005D15 is suitable for applications where extended frequency response or broader temperature range provides system benefits, with the understanding that response time is marginally slower. Both substitutes maintain regulatory compliance and through-hole mounting compatibility with the original HAW 05-P.

Frequently Asked Questions (FAQ)

Q: Can the HX 05-P be used as a direct replacement for the HAW 05-P in existing PCB designs?

A: Yes. Both components are through-hole mounted modules with identical pin configurations and electrical specifications (5A current sensing, ±15V supply, ±1% accuracy, 3µs response time). The HX 05-P provides an extended operating temperature range and is the manufacturer-recommended substitute.

Q: What is the difference between the HAW 05-P and L18P005D15 in terms of frequency response?

A: The HAW 05-P operates across DC ~ 50kHz, while the L18P005D15 extends to DC ~ 100kHz. The L18P005D15 is suitable for applications requiring measurement of higher frequency AC components within the 50kHz to 100kHz range.

Q: Are all three parts RoHS compliant?

A: Yes. The HAW 05-P, HX 05-P, and L18P005D15 are all RoHS compliant components.

Q: What is the significance of the "Not For New Designs" status on the HX 05-P?

A: This status indicates the HX 05-P is available for replacement and legacy system support but is not recommended for new product development. It remains suitable for maintaining existing systems and replacing obsolete HAW 05-P units.

Q: Does the L18P005D15 have the same accuracy specification as the HAW 05-P?

A: The HAW 05-P specifies ±1% accuracy. The L18P005D15 accuracy is not specified in the provided data. Verification of accuracy performance is necessary if this parameter is critical to the application.

Q: What is the maximum supply current difference between these parts?

A: The HAW 05-P draws a maximum of 18mA, while both the HX 05-P and L18P005D15 draw a maximum of 15mA. This 3mA reduction in the substitute parts may provide minor power supply design benefits.

Q: Can these parts be used interchangeably in terms of operating temperature?

A: The HAW 05-P operates from -10°C ~ 75°C. The HX 05-P extends this to -25°C ~ 85°C, and the L18P005D15 to -30°C ~ 80°C. Substitution is valid only if the application's operating temperature falls within the substitute part's specified range.

Q: What is the response time difference between the HAW 05-P and L18P005D15?

A: The HAW 05-P has a 3µs response time, while the L18P005D15 has a 5µs response time. For applications requiring faster transient response, the HAW 05-P or HX 05-P are preferred.
