Substitute Part Grouping Explanation

Substitute parts for the L18P005D15 are classified into three categories based on parametric alignment and functional equivalence:

MFR Recommended Substitute (L18P005D15-OP): Direct manufacturer upgrade from Tamura with identical current sensing specification (5A), matching sensor type (Hall Effect, open loop), equivalent output characteristics (ratiometric voltage), and compatible supply voltage range (±12V ~ 15V). This part transitions from obsolete to active product status while maintaining through-hole module packaging. The primary distinction is packaging format (tray versus bulk) and marginally increased supply current (18mA versus 15mA).

Parametric Equivalent (L18P003D15): Tamura Hall Effect sensor with reduced current sensing capacity (3A versus 5A). This part shares identical sensor architecture, output type, supply voltage (±15V), response time (5µs), operating temperature range, and bidirectional polarization. Selection of this part requires application-level verification that 3A sensing range satisfies circuit requirements.

Similar Manufacturer Alternative (HX 05-P): LEM USA Inc. Hall Effect current sensor matching the 5A sensing specification, single-channel configuration, ratiometric voltage output, and bidirectional operation. This part maintains ±15V supply voltage and through-hole module mounting. Distinctions include narrower frequency response (50kHz versus 100kHz), faster response time (3µs versus 5µs), extended operating temperature range (-25°C ~ 85°C versus -30°C ~ 80°C), and product status classified as not for new designs.

Engineering Selection Recommendations

Primary Selection: L18P005D15-OP

The L18P005D15-OP represents the manufacturer-recommended substitute for the obsolete L18P005D15. This part maintains active product status, ensuring long-term availability and supply chain continuity. Parametric alignment is complete across current sensing (5A), sensor architecture (Hall Effect, open loop), output configuration (ratiometric voltage), and electrical specifications. The transition from bulk to tray packaging accommodates standard manufacturing workflows. Increased maximum supply current (18mA versus 15mA) requires verification within power budget constraints but does not alter functional compatibility. RoHS compliance and identical ECCN/HTSUS classifications confirm regulatory equivalence.

Secondary Selection: L18P003D15

The L18P003D15 serves as a parametric equivalent when application requirements permit reduced current sensing capacity (3A maximum). This part maintains identical sensor type, output characteristics, supply voltage, response time, and operating temperature specifications. Selection requires explicit confirmation that circuit design accommodates the lower 3A sensing range. Product status remains obsolete, limiting long-term procurement viability.

Tertiary Selection: HX 05-P

The HX 05-P from LEM USA Inc. provides an alternative from a different manufacturer while preserving 5A current sensing capability and core Hall Effect architecture. This part exhibits faster response time (3µs versus 5µs) and extended operating temperature range (-25°C ~ 85°C), advantageous for demanding thermal environments. Frequency response limitation (50kHz versus 100kHz) requires verification against application bandwidth requirements. Product status classification as not for new designs restricts suitability for emerging designs but remains viable for legacy system support. RoHS compliance and matching ECCN/HTSUS codes confirm regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can L18P005D15-OP be used as a direct replacement for L18P005D15?

A: Yes. The L18P005D15-OP maintains identical current sensing specification (5A), sensor type (Hall Effect, open loop), output configuration (ratiometric voltage), supply voltage (±15V nominal), response time (5µs), operating temperature range (-30°C ~ 80°C), and through-hole module packaging. The primary difference is packaging format (tray versus bulk) and maximum supply current increase from 15mA to 18mA. Verification of power supply capability for the increased current draw is required.

Q: What are the limitations of using L18P003D15 as a substitute?

A: The L18P003D15 reduces current sensing capacity from 5A to 3A. All other electrical and mechanical parameters remain equivalent. This part is suitable only for applications where the maximum measurable current does not exceed 3A. Product status remains obsolete, presenting potential long-term supply constraints.

Q: Why is HX 05-P classified as a similar alternative rather than a direct equivalent?

A: The HX 05-P differs in three key parameters: frequency response (50kHz versus 100kHz), response time (3µs versus 5µs), and manufacturer (LEM USA Inc. versus Tamura). While current sensing (5A), sensor type (Hall Effect, open loop), output (ratiometric voltage), and supply voltage (±15V) align with the main part, the narrower frequency specification requires application-level verification. Product status as not for new designs further distinguishes this option.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (L18P005D15-OP, L18P003D15, and HX 05-P) carry RoHS Compliant certification, matching the compliance status of the main part L18P005D15.

Q: What packaging formats are available for these parts?

A: L18P005D15 and L18P003D15 are supplied in bulk packaging. L18P005D15-OP and HX 05-P are supplied in tray packaging. Packaging selection impacts handling, storage, and integration into automated assembly processes but does not affect electrical or mechanical functionality.

Q: Does the increased supply current of L18P005D15-OP (18mA versus 15mA) affect circuit design?

A: The 3mA increase in maximum supply current must be evaluated within the power supply design margin. If the original design allocated exactly 15mA, the substitute part requires confirmation that the power supply can deliver 18mA without voltage regulation degradation. In most applications with adequate power supply headroom, this difference is not limiting.

Q: Can HX 05-P be used in applications requiring 100kHz frequency response?

A: No. The HX 05-P frequency response is limited to 50kHz. Applications requiring measurement or signal transmission at frequencies above 50kHz must use L18P005D15-OP or L18P005D15 to maintain the full DC ~ 100kHz bandwidth.
