L18P010D15 Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The L18P010D15 is a Hall Effect open-loop bidirectional current sensor manufactured by Tamura, designed for AC/DC current measurement applications with a 10A sensing range. This component features ratiometric voltage output, 1-channel configuration, and through-hole module packaging. The part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing system support, design updates, and procurement continuity. Substitute parts must maintain functional compatibility across key electrical and mechanical parameters including current sensing range, output characteristics, supply voltage requirements, and mounting specifications.

Substitute Part Grouping Explanation

Substitute parts for the L18P010D15 are classified into three categories based on parametric alignment and functional compatibility:

MFR Recommended Substitute (Direct Replacement): L18P010D15-OP represents the manufacturer-recommended upgrade path. This part maintains the 10A current sensing specification, bidirectional polarization, Hall Effect open-loop topology, and single-channel configuration. The primary differences are packaging format (Tray vs. Bulk), active product status, and minor supply voltage range adjustment (±12V ~ 15V vs. ±15V). Maximum supply current increases from 15mA to 18mA, and frequency specification is not provided for this variant.

Parametric Equivalents (Lower Current Ratings): L18P005D15 and L18P003D15 are parametric equivalents with reduced current sensing capabilities (5A and 3A respectively). These parts share identical sensor topology, output characteristics, supply voltage (±15V), response time (5µs), linearity (±1%), operating temperature range, and mounting specifications. Selection of these parts requires application-level confirmation that the lower current sensing range is acceptable for the intended circuit function.

Similar Cross-Manufacturer Alternative: HX 10-P, manufactured by LEM USA Inc., provides equivalent 10A current sensing with Hall Effect open-loop architecture. This part maintains the 10A specification, bidirectional operation, single-channel output, and ±15V supply voltage. Differences include faster response time (3µs vs. 5µs), lower maximum operating frequency (50kHz vs. 100kHz), wider operating temperature range (-25°C ~ 85°C vs. -30°C ~ 80°C), and product status classified as "Not For New Designs."

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred Path): L18P010D15-OP is the manufacturer-recommended substitute and represents the optimal selection for applications requiring 10A current sensing with minimal design modification. This part maintains full parametric compatibility with the original L18P010D15 while offering active product status and ROHS3 compliance certification. The transition from Bulk to Tray packaging and the expanded supply voltage range (±12V ~ 15V) provide improved procurement flexibility and supply chain stability.

For Current-Reduced Applications: L18P005D15 and L18P003D15 are suitable only when application requirements permit reduced current sensing capability. These parts maintain identical electrical topology, output characteristics, and thermal specifications as the original part. Selection requires explicit confirmation that the 5A or 3A current range satisfies circuit design requirements.

For Cross-Manufacturer Substitution: HX 10-P from LEM USA Inc. provides equivalent 10A current sensing functionality with improved response time (3µs). However, this part carries "Not For New Designs" status and operates at reduced maximum frequency (50kHz vs. 100kHz). Selection of this alternative is appropriate only when L18P010D15-OP availability is constrained and application frequency requirements do not exceed 50kHz.

All substitute parts maintain through-hole mounting compatibility, bidirectional Hall Effect open-loop topology, and ratiometric voltage output configuration. Supply voltage, operating temperature, and linearity specifications remain consistent across recommended substitutes, ensuring functional equivalence in established circuit designs.

Frequently Asked Questions (FAQ)

Q: Can L18P010D15-OP be used as a direct replacement for L18P010D15 without circuit modification?

A: Yes. L18P010D15-OP maintains identical current sensing range (10A), output type (ratiometric voltage), supply voltage specification (±15V within the ±12V ~ 15V range), response time (5µs), linearity (±1%), and through-hole module mounting. The primary differences are packaging format and active product status. No circuit modification is required.

Q: What is the key difference between L18P010D15 and L18P005D15?

A: The primary difference is current sensing range: L18P010D15 measures up to 10A, while L18P005D15 measures up to 5A. Both parts share identical sensor topology, output characteristics, supply voltage (±15V), response time (5µs), and operating temperature range. Selection of L18P005D15 requires confirmation that the application current does not exceed 5A.

Q: Is HX 10-P a suitable replacement for L18P010D15?

A: HX 10-P provides equivalent 10A current sensing with Hall Effect open-loop architecture and maintains ±15V supply voltage and bidirectional operation. However, HX 10-P operates at maximum frequency of 50kHz compared to L18P010D15's 100kHz capability, and carries "Not For New Designs" status. Selection is appropriate only when frequency requirements do not exceed 50kHz and L18P010D15-OP is unavailable.

Q: What packaging format differences exist between substitute parts?

A: L18P010D15 and L18P005D15 and L18P003D15 are supplied in Bulk packaging, while L18P010D15-OP and HX 10-P are supplied in Tray packaging. Both formats are compatible with through-hole mounting applications. Tray packaging typically provides improved handling and automated assembly compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. L18P010D15, L18P005D15, and L18P003D15 are RoHS Compliant. L18P010D15-OP is ROHS3 Compliant, representing an enhanced compliance certification. HX 10-P is RoHS Compliant. All parts meet regulatory requirements for hazardous substance restriction.

Q: What is the significance of product status classifications?

A: L18P010D15 is classified as Obsolete, indicating discontinued manufacturing. L18P010D15-OP is Active, indicating current production and recommended for new designs. HX 10-P is classified as "Not For New Designs," indicating limited availability and unsuitability for new product development. For ongoing support and new applications, L18P010D15-OP is the preferred selection.

Q: Can L18P003D15 or L18P005D15 be used in applications originally designed for L18P010D15?

A: Only if the application current requirement does not exceed the substitute part's rating (3A for L18P003D15, 5A for L18P005D15). These parts maintain identical electrical topology and output characteristics but provide reduced current sensing range. Circuit-level verification is required to confirm compatibility.
