L18P025S05R Hall Effect Current Sensor - Equivalent & Substitute Parts

Part Overview

The L18P025S05R is an active Hall Effect open-loop current sensor manufactured by Tamura, designed for bidirectional AC/DC current measurement applications. This module provides ratiometric voltage output with a 25A sensing range and operates across a frequency spectrum from DC to 100kHz. The part is currently in active production status with 1081 units in stock inventory.

Substitute parts are identified when design requirements permit operation at reduced current-sensing specifications while maintaining compatibility across all other critical electrical and mechanical parameters. Alternative models within the L18PXXXS05 series provide equivalent functionality for applications where the full 25A sensing capacity is not required.

Substitute Part Grouping Explanation

Substitution eligibility for the L18P025S05R is determined by strict adherence to the following parameters:

Fixed Parameters (Must Match Exactly):

• Sensor Type: Hall Effect, Open Loop
• Number of Channels: 1
• 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
• Series: L18PXXXS05

Variable Parameter (Allows Substitution):

• Current - Sensing: 25A (main part) → 20A (substitute part)

The L18P020S05 qualifies as a parametric equivalent because it maintains all fixed electrical and mechanical specifications while operating at a reduced current-sensing capacity of 20A. This substitution is valid only for applications where the maximum measurable current does not exceed 20A.

Parameter Comparison

Engineering Selection Recommendations

L18P025S05R Selection Criteria:

• Applications requiring current measurement up to 25A
• Designs where maximum sensing range is a system requirement
• RoHS Compliant status required
• Active production status with established supply chain

L18P020S05 Selection Criteria:

• Applications with maximum current measurement requirement of 20A or less
• Designs where reduced current-sensing capacity does not impact system performance
• ROHS3 Compliant status acceptable
• Active production status with established supply chain

Both parts maintain identical electrical performance characteristics across frequency response, linearity, response time, and supply specifications. Selection between these parts depends solely on whether the application's maximum current measurement requirement aligns with the 25A or 20A sensing capacity. Both parts are in active production with adequate inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the L18P020S05 be used as a direct replacement for the L18P025S05R?

A: The L18P020S05 is a parametric equivalent only for applications where the maximum measurable current does not exceed 20A. If your circuit requires measurement capability up to 25A, the L18P025S05R is the appropriate selection. Both parts share identical electrical and mechanical specifications except for current-sensing range.

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

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents a more recent version of the standard. Both parts meet hazardous substance restrictions and are suitable for applications requiring RoHS compliance.

Q: Are the mounting footprints identical between these parts?

A: Yes. Both the L18P025S05R and L18P020S05 feature Through Hole mounting type and Module package configuration. PCB layout and mounting hole patterns are identical.

Q: Can I use the L18P025S05R in an application designed for the L18P020S05?

A: Yes. The L18P025S05R provides extended current-sensing capability (25A versus 20A) while maintaining all other electrical and mechanical specifications. It is a direct upgrade path for applications requiring increased current measurement range.

Q: What is the output voltage relationship to measured current?

A: Both parts provide ratiometric voltage output. The output voltage scales proportionally with the measured current within the specified sensing range. Consult the detailed product datasheet for the specific voltage-to-current transfer function.

Q: Are there other parts in the L18PXXXS05 series available?

A: The provided documentation identifies the L18P025S05R and L18P020S05 as active parts within the L18PXXXS05 series. Additional variants may exist; consult the manufacturer's complete product portfolio for the full series lineup.
