Substitute Part Grouping Explanation

Substitution within the L18PXXXS05 series is determined by the following critical parameters that must remain constant across equivalent parts:

Fixed Parameters (Non-Negotiable for Substitution):

• Sensor Type: Hall Effect, Open Loop
• Output Type: Ratiometric, Voltage
• Number of Channels: 1
• 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 (Defines Current Sensing Capability):

• Current - Sensing: Varies by model designation

The L18P020S05 qualifies as a parametric equivalent within this series, with the primary distinction being the current sensing rating of 20A versus the 50A rating of the L18P050S05. Both parts maintain identical electrical characteristics, supply requirements, response specifications, and environmental operating parameters.

Parameter Comparison

Engineering Selection Recommendations

L18P050S05 Primary Selection Criteria:

• Applications requiring 50A current sensing range
• Systems designed for maximum current measurement capability within the L18PXXXS05 series
• Designs where full 50A measurement capacity is specified

L18P020S05 Substitution Applicability:

• Applications with current measurement requirements not exceeding 20A
• Systems where the 20A sensing range satisfies functional requirements
• Scenarios where component availability or inventory optimization necessitates selection of the lower-rated variant

Both parts maintain active production status and full RoHS compliance. The L18P050S05 carries RoHS Compliant certification, while the L18P020S05 carries ROHS3 Compliant certification. Both certifications satisfy regulatory requirements for their respective applications.

Selection between these parts depends exclusively on the maximum current measurement requirement of the target application. All other electrical, thermal, and mechanical characteristics remain functionally equivalent.

Frequently Asked Questions (FAQ)

Q: Can the L18P020S05 be used as a direct replacement for the L18P050S05?

A: The L18P020S05 functions as a parametric equivalent only when the application's maximum current measurement requirement does not exceed 20A. If the system design requires measurement capability up to 50A, the L18P020S05 is not suitable. All other electrical and mechanical specifications are identical.

Q: What is the primary difference between these two parts?

A: The sole functional difference is the current sensing rating. The L18P050S05 measures up to 50A, while the L18P020S05 measures up to 20A. Both employ identical Hall Effect open-loop technology, supply voltage, response time, frequency response, and output characteristics.

Q: Are the mounting and package specifications identical?

A: Yes. Both parts use Through Hole mounting type and Module package configuration. They are mechanically compatible within the same PCB footprint and assembly process.

Q: Do both parts meet RoHS requirements?

A: Yes. The L18P050S05 is RoHS Compliant, and the L18P020S05 is ROHS3 Compliant. Both satisfy regulatory compliance requirements for their respective applications.

Q: What is the operating temperature range for both sensors?

A: Both the L18P050S05 and L18P020S05 operate across the identical temperature range of -30°C to 80°C.

Q: Are the supply voltage and power consumption specifications the same?

A: Yes. Both parts require 5V supply voltage and draw a maximum of 15mA supply current.

Q: What frequency range do these sensors support?

A: Both sensors operate across DC to 100kHz frequency range with identical 5µs response time and ±1% linearity specifications.
