Tamura L07P020S05 Hall Effect Current Sensor 20A AC/DC Equivalent & Substitute Parts

Part Overview

The Tamura L07P020S05 is a Hall Effect open-loop bidirectional current sensor rated for 20A AC/DC measurement. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design support and procurement. The L07P020S05 operates as a single-channel ratiometric voltage output module with 5V supply, suitable for applications requiring AC/DC current sensing across a frequency range of DC to 100kHz. Substitute parts are selected from the active L18PXXXS05 series, which maintains core electrical and mechanical compatibility while offering extended product lifecycle support.

The L18PXXXS05 series provides direct substitutes across multiple current ratings. Selection of the appropriate substitute depends on the application's actual current measurement requirement. The L18P020S05 and L18P020S05R are full functional equivalents to the L07P020S05 for 20A applications. Lower current-rated variants (L18P003S05, L18P005S05, L18P010S05, L18P015S05) serve applications with reduced current sensing needs while maintaining identical electrical characteristics and form factor.

Engineering Selection Recommendations

Primary Substitute for 20A Applications:

The L18P020S05 and L18P020S05R are the recommended direct replacements for the obsolete L07P020S05. Both parts maintain identical electrical specifications, frequency response, and thermal operating range. The L18P020S05 is available in bulk packaging with 1040 units in stock and carries RoHS3 compliance certification. The L18P020S05R variant is also active with 979 units available. Both support the same through-hole module form factor and 5V supply architecture.

Secondary Substitutes for Reduced Current Applications:

When application requirements permit lower current sensing ratings, the L18P series offers alternatives:

L18P015S05 / L18P015S05R: 15A rating, 1019 / 979 units in stock
L18P010S05 / L18P010S05R: 10A rating, 1005 / 663 units in stock
L18P005S05 / L18P005S05R: 5A rating, 887 / 812 units in stock
L18P003S05 / L18P003S05R: 3A rating, 775 / 835 units in stock

All L18PXXXS05 variants maintain RoHS compliance and identical electrical performance characteristics. Selection should be based on the actual maximum current measurement requirement of the application. Oversizing current rating introduces unnecessary cost; undersizing creates measurement saturation risk.

Compatibility Considerations:

The L07P010S05 remains active with 987 units in stock and serves as an alternative for 10A applications within the L07P series. However, migration to the L18PXXXS05 series is preferred due to extended product lifecycle and higher inventory availability across all current ratings.

Frequently Asked Questions (FAQ)

Q: Can the L18P020S05 directly replace the L07P020S05 in existing designs?

A: Yes. The L18P020S05 maintains identical electrical specifications, frequency response (DC ~ 100kHz), linearity (±1%), supply voltage (5V), response time (5µs), operating temperature range (-30°C ~ 80°C), and through-hole module form factor. Both are Hall Effect open-loop bidirectional sensors with ratiometric voltage output. The primary difference is product status: L07P020S05 is obsolete while L18P020S05 is active with extended availability.

Q: What is the difference between L18P020S05 and L18P020S05R?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The "R" designation indicates a variant within the same product line. Both are active, RoHS compliant, and available in high quantities. Selection between them depends on supplier availability and internal part numbering requirements.

Q: Can I use a lower current-rated sensor such as L18P015S05 if my application only requires 15A measurement?

A: Yes, if your application's maximum current requirement does not exceed 15A. The L18P015S05 provides identical electrical performance, frequency response, and output characteristics as the 20A-rated variants. Using the appropriate current rating for your application optimizes cost and measurement accuracy within the sensor's linear operating range.

Q: What is the difference in maximum supply current between L07P020S05 (30mA) and L18P020S05 (15mA)?

A: The L18P020S05 operates at 15mA maximum supply current compared to 30mA for the L07P020S05. This represents improved power efficiency in the newer L18PXXXS05 series design. Both values remain well within typical circuit power budgets. Verify that your power supply can deliver the specified maximum current; the L18P020S05 requirement of 15mA is lower and presents no compatibility risk.

Q: Are all L18PXXXS05 variants pin-compatible with the L07P020S05?

A: All parts in this comparison maintain identical through-hole module form factor and 5V supply architecture. Mechanical compatibility is confirmed across the L07P and L18PXXXS05 series. Verify PCB footprint and connector specifications in your design documentation before final substitution.

Q: What is the inventory status for substitute parts?

A: The L18P020S05 has 1040 units in stock (bulk packaging). The L18P020S05R has 979 units available. All lower current-rated L18PXXXS05 variants maintain inventory above 600 units. The L07P010S05 has 987 units in stock as an alternative within the original L07P series.

Q: Do all substitute parts carry RoHS certification?

A: Yes. All L18PXXXS05 series parts carry RoHS3 compliance. The L07P020S05 and L07P010S05 carry RoHS compliance. All parts meet environmental regulatory requirements for electronic component procurement.
