L18P030S05 Hall Effect Current Sensor - Equivalent & Substitute Parts

Part Overview

The L18P030S05 is an active Hall Effect current sensor manufactured by Tamura, designed for AC/DC current measurement applications. This open-loop, bidirectional module provides ratiometric voltage output with a 30A sensing range and operates across a frequency spectrum from DC to 100kHz. The part is currently in active production status with 713 units available in inventory.

Identifying equivalent and substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or application-specific current measurement requirements that may differ from the primary 30A specification.

Substitute Part Grouping Explanation

Substitution eligibility for the L18P030S05 is determined by strict adherence to the following critical parameters:

Fixed Compatibility Parameters:

• Manufacturer Series: L18PXXXS05 (same family designation)
• Sensor Type: Hall Effect, Open Loop
• Output Type: Ratiometric, Voltage
• Frequency Range: DC ~ 100kHz
• Linearity: ±1%
• Voltage Supply: 5V
• Response Time: 5µs
• Current Supply (Max): 15mA
• Operating Temperature: -30°C ~ 80°C
• Polarization: Bidirectional
• Mounting Type: Through Hole
• Package / Case: Module

Variable Parameter (Substitution Basis):

• Current - Sensing: 20A (substitute) vs. 30A (primary)

The L18P020S05 qualifies as a parametric equivalent within the L18PXXXS05 series. This substitute maintains identical electrical characteristics, supply requirements, frequency response, and thermal specifications. The primary distinction is the current sensing range, which is reduced from 30A to 20A.

Engineering Selection Recommendations

Primary Part Selection (L18P030S05): Select the L18P030S05 when applications require current measurement up to 30A. This part maintains active production status with established RoHS compliance certification and adequate inventory levels.

Substitute Part Selection (L18P020S05): The L18P020S05 serves as a direct substitute for applications with maximum current measurement requirements of 20A or less. This substitute maintains identical electrical performance characteristics, supply voltage requirements, frequency response, and thermal operating range. The L18P020S05 demonstrates higher inventory availability (1040 units) and meets ROHS3 compliance standards.

Selection Criteria:

• Use L18P030S05 for applications requiring the full 30A measurement capability
• Use L18P020S05 for applications with current measurement requirements not exceeding 20A
• Both parts share identical interface characteristics, mounting methodology, and signal conditioning specifications
• Both parts maintain active production status with current regulatory compliance

Frequently Asked Questions (FAQ)

Q: Can the L18P020S05 be used as a direct replacement for the L18P030S05?

A: The L18P020S05 functions as a parametric equivalent only for applications where the maximum measured current does not exceed 20A. All electrical interface characteristics, supply requirements, output signal conditioning, and mounting specifications are identical. Applications requiring current measurement between 20A and 30A must use the L18P030S05.

Q: What are the key differences between these two parts?

A: The primary difference is the current sensing range: L18P030S05 measures up to 30A, while L18P020S05 measures up to 20A. All other specifications—including sensor type, output format, frequency response, supply voltage, response time, operating temperature range, and mounting configuration—are identical.

Q: Are there any compatibility issues with PCB layout or connector interfaces?

A: No compatibility issues exist. Both parts use identical Through Hole mounting types and Module package configurations. PCB layouts designed for either part are interchangeable.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both certifications indicate compliance with hazardous substance restrictions. ROHS3 represents the current regulatory standard. Both parts meet environmental compliance requirements for their respective production periods.

Q: Which part should be selected for new designs?

A: For new designs, select based on the maximum current measurement requirement. If the application measures currents up to 20A, either part is suitable; the L18P020S05 offers higher inventory availability. If the application requires measurement capability up to 30A, the L18P030S05 is the appropriate selection.

Q: Are both parts available in the same packaging format?

A: Yes. Both the L18P030S05 and L18P020S05 are supplied as Through Hole mounted modules. The L18P030S05 is available in standard packaging, while the L18P020S05 is available in Bulk packaging.
