Engineering Selection Recommendations

Primary Selection: L07P030D15S

The L07P030D15S is the manufacturer-recommended substitute for the L07P030D15. This part maintains identical current sensing capacity (30A), electrical specifications, and operating parameters while offering expanded functionality through dual-channel configuration. The L07P030D15S carries active product status, ensuring ongoing availability and manufacturer support. Both parts comply with RoHS requirements and share identical supply voltage (±15V), response time (5µs), operating temperature range (-30°C to 80°C), and through-hole module packaging.

Secondary Selection: L18P025D15

For applications where 30A sensing capacity is not required, the L18P025D15 provides the closest parametric match with 25A current sensing range. This part maintains all core electrical characteristics including ±15V supply, 5µs response time, ±1% linearity, DC to 100kHz frequency response, and bidirectional measurement capability. The L18P025D15 is RoHS compliant and uses identical through-hole module packaging.

Tertiary Selections: L18P010D15, L18P005D15, L18P003D15

These parts provide parametric equivalence for applications with lower current measurement requirements (10A, 5A, and 3A respectively). All three maintain the complete set of electrical and mechanical specifications required for direct substitution within their respective current rating boundaries. Each part is RoHS compliant and utilizes the same module form factor with through-hole mounting.

Compliance Considerations:

All substitute parts maintain RoHS compliance status consistent with the original L07P030D15. The L07P030D15S is the only active product in this substitution group, providing the most reliable long-term availability for new designs and ongoing production requirements.

Frequently Asked Questions (FAQ)

Q: Can the L07P030D15S directly replace the L07P030D15 in existing designs?

A: Yes. The L07P030D15S maintains identical electrical specifications for current sensing (30A), supply voltage (±15V), response time (5µs), operating temperature range (-30°C to 80°C), and output characteristics (ratiometric voltage). The primary difference is the addition of a second measurement channel. Existing single-channel circuit implementations will function without modification, with the second channel remaining unused.

Q: What is the key difference between the L07P030D15 and the lower-rated current sensors (L18P series)?

A: The primary difference is the current sensing range. The L07P030D15 measures up to 30A, while the L18P series provides lower ranges: L18P025D15 (25A), L18P010D15 (10A), L18P005D15 (5A), and L18P003D15 (3A). All parts share identical sensor technology (Hall Effect open-loop), output type (ratiometric voltage), supply voltage (±15V), response time (5µs), operating temperature range (-30°C to 80°C), linearity (±1%), and through-hole module packaging. Selection depends on the maximum current to be measured in the application.

Q: Are all substitute parts RoHS compliant?

A: Yes. The L07P030D15, L07P030D15S, L18P025D15, L18P010D15, L18P005D15, and L18P003D15 are all RoHS compliant.

Q: What is the significance of the L07P030D15S being an active product while the original L07P030D15 is obsolete?

A: Active product status indicates that the L07P030D15S is currently manufactured and supported by Tamura, ensuring reliable long-term availability for procurement and design continuity. The obsolete status of the L07P030D15 means it is no longer in production, making the L07P030D15S the recommended path for new designs and ongoing production requirements.

Q: Can I use a lower-rated current sensor (such as L18P010D15) in place of the L07P030D15?

A: Only if your application's maximum current requirement does not exceed the substitute part's rating. The L18P010D15 is suitable for applications measuring up to 10A. Using a lower-rated sensor in an application exceeding its current range will result in measurement saturation and inaccuracy. All other electrical and mechanical parameters remain compatible.

Q: What mounting considerations apply to these substitute parts?

A: All substitute parts use identical through-hole mounting configuration and module packaging. No PCB layout modifications are required for mechanical compatibility. Verify that existing through-hole pad spacing and component clearances accommodate the module form factor.

Q: Do all substitute parts operate at the same frequency range?

A: The L07P030D15 and all L18P series parts (L18P003D15, L18P005D15, L18P010D15, L18P025D15) operate across DC to 100kHz frequency range. The L07P030D15S does not specify frequency range in the provided data; verify frequency requirements with the manufacturer if this parameter is critical for your application.

Q: What is the difference in maximum supply current between the L07P030D15 and the L18P series?

A: The L07P030D15 and L07P030D15S require a maximum supply current of 30mA. The L18P series parts (L18P003D15, L18P005D15, L18P010D15, L18P025D15) require a maximum supply current of 15mA. This difference reflects the lower current sensing ranges of the L18P series. Verify that your power supply can deliver the required current for the selected part.
