Output Configuration: Ratiometric voltage output
Supply Voltage: 5V
Frequency Response: DC ~ 100kHz minimum
Mounting: Through Hole module package
Operating Temperature Range: -30°C ~ 80°C minimum

Current Sensing Capacity Consideration: The L07P005S05 operates at 5A sensing range. Substitute parts are grouped into two categories:

Direct Current Rating Match (5A): L18P005S05, L18P005S05R
Reduced Current Rating (3A): L18P003S05, L18P003S05R

All substitute parts belong to the active L18PXXXS05 series from Tamura, ensuring design continuity and long-term availability. The transition from L07P to L18P series represents a product line evolution while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Primary Substitutes (Recommended for Direct Replacement):

L18P005S05 and L18P005S05R are the preferred substitutes for the L07P005S05. Both parts maintain identical current sensing capacity (5A), electrical specifications, and mechanical compatibility. These parts are active products from Tamura's current L18P series, ensuring long-term availability and supply chain stability. The "R" designation in L18P005S05R indicates a packaging or reel configuration variant; both versions are functionally equivalent.

Secondary Substitutes (Current Rating Consideration):

L18P003S05 and L18P003S05R operate at 3A sensing capacity, compared to the 5A rating of the original L07P005S05. These parts are suitable for applications where the measured current does not exceed 3A. All other electrical parameters, including supply voltage, frequency response, linearity, response time, and operating temperature range, remain identical to the primary substitutes. The reduced current supply requirement (15mA versus 30mA) represents an improvement in power efficiency.

Compliance and Certification:

All substitute parts maintain RoHS compliance status and share identical ECCN (EAR99) and HTSUS (9030.33.3800) classifications with the original part, ensuring regulatory continuity for export and procurement documentation.

Frequently Asked Questions (FAQ)

Q: Can L18P003S05 or L18P003S05R be used as a direct replacement for L07P005S05?

A: L18P003S05 and L18P003S05R are functionally compatible substitutes only for applications where the maximum measured current does not exceed 3A. If the application requires measurement of currents up to 5A, these parts are not suitable. For applications operating within the 3A range, these parts provide identical electrical performance and improved power efficiency.

Q: What is the difference between L18P005S05 and L18P005S05R?

A: Both parts are electrically and functionally identical. The "R" designation indicates a packaging or reel configuration variant. Selection between these two should be based on procurement and assembly requirements rather than electrical performance.

Q: Are all substitute parts pin-compatible with the L07P005S05?

A: All substitute parts share identical through-hole module mounting type and package configuration. Mechanical and electrical interface compatibility is maintained across the L07P005S05 and all L18PXXXS05 series substitutes.

Q: What is the impact of the reduced current supply requirement in L18P series parts?

A: The L18P series parts require a maximum of 15mA supply current compared to 30mA for the L07P005S05. This represents a 50% reduction in power consumption and is an improvement for power-constrained applications. This change does not affect measurement accuracy, linearity, or frequency response.

Q: Are there any temperature or frequency limitations when substituting these parts?

A: No. All substitute parts maintain the identical operating temperature range (-30°C ~ 80°C) and frequency response (DC ~ 100kHz) as the original L07P005S05. Substitution does not introduce any thermal or frequency-related limitations.

Q: Why is the L07P005S05 classified as obsolete?

A: The L07P005S05 has been superseded by the active L18PXXXS05 series. Tamura has transitioned its current sensor product line to the L18P series, which provides equivalent or improved performance characteristics while maintaining design compatibility.
