Tamura L07P015S05 Hall Effect Current Sensor: Equivalent & Substitute Parts

Part Overview

The Tamura L07P015S05 is a Hall Effect open-loop bidirectional current sensor rated for 15A AC/DC measurement. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The sensor operates at 5V supply with ratiometric voltage output, 5µs response time, and supports frequencies from DC to 100kHz. Substitute parts must maintain functional compatibility across electrical specifications, mechanical mounting, and environmental operating ranges.

Current Sensing Rating Substitution Logic: The L07P015S05 is rated for 15A measurement. Substitute parts are grouped by current sensing capability. Parts rated at 15A provide direct functional equivalence. Parts rated below 15A (10A, 5A, 3A) are suitable only when application requirements permit lower current measurement ranges. Parts rated above 15A are not provided in the substitute list.

Series Transition: The L07P series (obsolete) transitions to the L18PXXXS05 series (active). All L18P variants maintain identical electrical and mechanical specifications except for current supply maximum, which is reduced from 30mA to 15mA in the L18P series. This reduction does not affect functional compatibility for standard applications.

Engineering Selection Recommendations

Primary Substitutes (15A Rating):

L18P015S05 and L18P015S05R are the preferred direct replacements for the obsolete L07P015S05. Both parts maintain the 15A current sensing rating and all electrical specifications. Both are active products with RoHS compliance certification. The L18P015S05R variant provides higher inventory availability (979 Pcs vs. 1019 Pcs). The transition from L07P to L18P series includes a reduction in maximum supply current from 30mA to 15mA; this change does not affect functional performance in standard applications.

Secondary Substitutes (10A Rating):

L18P010S05 and L18P010S05R are suitable when application requirements permit measurement of currents up to 10A. These parts are active products with identical electrical characteristics except for current sensing range. Selection between L18P010S05 (1005 Pcs) and L18P010S05R (663 Pcs) depends on inventory availability requirements.

L07P010S05 remains available as an active product within the original L07P series, maintaining the 30mA supply current specification of the main part.

Lower Current Alternatives (5A and 3A Ratings):

L18P005S05, L18P005S05R, L18P003S05, and L18P003S05R are suitable only for applications requiring measurement of currents at 5A or 3A respectively. These parts are active products with all core electrical specifications maintained. Supply current is reduced to 15mA in the L18P series.

Compliance and Certification:

All substitute parts carry RoHS Compliant certification, matching the main part specification. All parts are classified under ECCN EAR99 and HTSUS 9030.33.3800, consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can L18P015S05 directly replace L07P015S05 in existing designs?

A: Yes. L18P015S05 and L18P015S05R maintain identical electrical and mechanical specifications. The maximum supply current is reduced from 30mA to 15mA in the L18P series. This reduction does not affect functional compatibility for standard applications. Through-hole mounting and module package type are identical.

Q: What is the difference between L18P015S05 and L18P015S05R?

A: Both parts are functionally identical. The "R" designation indicates a variant within the L18PXXXS05 series. Electrical specifications, current rating, response time, frequency range, and operating temperature are identical. Selection should be based on inventory availability and procurement lead time.

Q: Can a 10A-rated sensor substitute for a 15A-rated sensor?

A: L18P010S05 and L18P010S05R are suitable only when application requirements permit measurement of currents up to 10A. These parts cannot measure currents above 10A. If the application requires 15A measurement capability, use L18P015S05 or L18P015S05R.

Q: Are 5A and 3A rated sensors compatible with 15A applications?

A: L18P005S05, L18P005S05R, L18P003S05, and L18P003S05R are rated for maximum currents of 5A and 3A respectively. These parts are not suitable for applications requiring 15A measurement capability. Current sensing range is a critical parameter that must match application requirements.

Q: What is the significance of the supply current reduction from 30mA to 15mA?

A: The L07P series specifies 30mA maximum supply current, while the L18P series specifies 15mA. This reduction reflects improved power efficiency in the newer series design. For standard applications, the 15mA specification is sufficient and does not impact functional performance or measurement accuracy.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed carry RoHS Compliant certification, matching the original L07P015S05 specification. All parts are suitable for applications requiring RoHS compliance.

Q: What mounting considerations apply to substitute parts?

A: All substitute parts use Through Hole mounting type and Module package configuration, identical to the original L07P015S05. PCB layout and mechanical integration requirements remain unchanged.

Q: Why is L07P015S05 classified as obsolete?

A: The L07P series has been superseded by the L18PXXXS05 series. Tamura has transitioned production to the newer L18P line, which offers improved specifications and power efficiency. The L07P015S05 remains available in limited inventory (682 Pcs) but is no longer in active production.

Q: Can L07P010S05 be used as a substitute for L07P015S05?

A: L07P010S05 is suitable only when application requirements permit measurement of currents up to 10A. This part maintains the 30mA supply current specification of the original L07P series and remains an active product. However, it cannot measure currents above 10A.
