HAW 15-P Current Sensor Equivalent & Substitute Parts

Part Overview

The HAW 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 component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system maintenance, redesign, and procurement planning. The sensor operates as an open-loop, bidirectional transducer with ratiometric voltage output, suitable for applications requiring galvanic isolation and wide frequency response.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HAW 15-P is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Sensor Type: Hall Effect, Open Loop configuration
• Output Type: Ratiometric, Voltage output
• Measurement Capability: AC/DC bidirectional sensing
• Supply Voltage: ±15V operation
• Mounting: Through Hole package
• Polarization: Bidirectional operation

Secondary Compatibility Factors:

• Current sensing range (15A nominal)
• Frequency response bandwidth (minimum DC ~ 50kHz)
• Linearity and accuracy specifications (±1%)
• Response time performance (3µs or faster)
• Operating temperature envelope (-10°C ~ 75°C minimum)

The substitute part L18P005D15 (Tamura) shares the core functional architecture of Hall Effect open-loop sensing with ratiometric voltage output and ±15V supply compatibility. However, this part operates at a reduced current sensing range of 5A, which represents a functional limitation for direct 1:1 substitution in applications requiring full 15A measurement capacity.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility Assessment:

The L18P005D15 (Tamura) demonstrates functional compatibility with the HAW 15-P in the following aspects:

• Identical Hall Effect open-loop sensor architecture
• Matching ratiometric voltage output configuration
• Equivalent ±15V dual-supply operation
• Bidirectional AC/DC measurement capability
• Through-hole mounting compatibility
• Identical linearity specification (±1%)
• Extended operating temperature range (-30°C ~ 80°C vs. -10°C ~ 75°C)
• Superior frequency response (DC ~ 100kHz vs. DC ~ 50kHz)
• Lower supply current requirement (15mA vs. 18mA)

Critical Limitation:

The L18P005D15 operates at a maximum current sensing range of 5A, compared to the HAW 15-P's 15A capacity. This represents a three-fold reduction in current measurement range. Substitution is applicable only in applications where the actual measured current does not exceed 5A.

Compliance Status:

Both components are classified as obsolete products. The L18P005D15 carries RoHS Compliant certification, whereas the HAW 15-P is REACH Unaffected. Both share identical ECCN (EAR99) and HTSUS (9030.33.3800) classifications, indicating equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the L18P005D15 directly replace the HAW 15-P in all applications?

A: No. While both sensors share identical Hall Effect open-loop architecture and ratiometric voltage output, the L18P005D15 is rated for 5A maximum current sensing versus the HAW 15-P's 15A rating. Direct substitution is valid only for applications where measured current remains below 5A.

Q: What are the key electrical compatibility factors between these sensors?

A: Both sensors operate on ±15V dual supply, produce ratiometric voltage output, support bidirectional AC/DC measurement, and maintain ±1% linearity. Supply current requirements differ slightly (18mA vs. 15mA), and frequency response differs (50kHz vs. 100kHz).

Q: Are there package or mounting differences between these parts?

A: Both components use through-hole mounting. The HAW 15-P is specified as an 8-DIP Module, while the L18P005D15 is designated as a Module without specific DIP pin count specification in the provided data.

Q: What is the temperature operating envelope for each sensor?

A: The HAW 15-P operates from -10°C to 75°C. The L18P005D15 provides an extended range of -30°C to 80°C, offering broader thermal capability for cold-start and high-temperature applications.

Q: How do response times compare between these sensors?

A: The HAW 15-P has a 3µs response time, while the L18P005D15 has a 5µs response time. For applications requiring sub-microsecond transient response, the HAW 15-P specification is superior.

Q: Are there regulatory or compliance differences?

A: The L18P005D15 is RoHS Compliant, while the HAW 15-P is REACH Unaffected. Both share identical ECCN (EAR99) export classification and HTSUS tariff code (9030.33.3800).
