Engineering Selection Recommendations

Primary Recommendation: L18P020D15-OP

The L18P020D15-OP is the manufacturer-recommended substitute for the obsolete L18P020D15. This part maintains identical current sensing capability (20A) and core sensor specifications while offering active product status. The L18P020D15-OP provides enhanced supply voltage flexibility (±12V to ±15V versus fixed ±15V) and slightly increased maximum supply current (18mA versus 15mA). Both parts are RoHS compliant with equivalent linearity and response time characteristics. The L18P020D15-OP is packaged in Tray format and is currently in active production.

Alternative for 20A Applications: HX 20-P

The HX 20-P from LEM USA Inc. provides equivalent 20A current sensing with identical Hall Effect open-loop technology and ratiometric voltage output. This part offers a faster response time (3µs versus 5µs) and extended operating temperature range (-25°C to 85°C). However, the HX 20-P carries a "Not For New Designs" status. This part is suitable for legacy system maintenance or replacement scenarios where existing designs already incorporate this component.

Lower Current Rating Alternatives: L18P010D15, L18P005D15, L18P003D15

These Tamura parts provide parametric equivalence in sensor technology and output characteristics but with reduced current sensing ratings (10A, 5A, and 3A respectively). These components are applicable only when circuit requirements permit operation at lower current thresholds. All three parts are classified as obsolete.

Frequently Asked Questions (FAQ)

Q: Can the L18P020D15 be directly replaced with L18P020D15-OP?

A: Yes. The L18P020D15-OP is the manufacturer-recommended direct substitute. Both parts share identical current sensing rating (20A), sensor technology (Hall Effect open-loop), output type (ratiometric voltage), and core electrical specifications. The primary difference is product status: L18P020D15-OP is active production while L18P020D15 is obsolete.

Q: What is the difference between the L18P020D15 and lower-rated parts like L18P010D15?

A: The primary difference is current sensing capacity. The L18P020D15 measures up to 20A, while L18P010D15, L18P005D15, and L18P003D15 measure 10A, 5A, and 3A respectively. All parts share identical sensor technology, output characteristics, response time (5µs), linearity (±1%), and operating temperature range. Lower-rated parts are substitutes only when circuit current requirements are below their respective ratings.

Q: Is the HX 20-P a suitable replacement for new designs?

A: The HX 20-P is not recommended for new designs. This LEM USA Inc. part carries "Not For New Designs" status. It is suitable for replacement or maintenance of existing systems already using this component. For new applications, the L18P020D15-OP is the appropriate choice.

Q: What are the packaging differences among substitute parts?

A: L18P020D15 is supplied in bulk packaging, while L18P020D15-OP is supplied in Tray format. L18P003D15, L18P005D15, and L18P010D15 are supplied in bulk packaging. HX 20-P is supplied in Tray format. Packaging selection depends on procurement volume and assembly requirements.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS compliant. L18P020D15-OP specifically carries ROHS3 compliance, while other Tamura parts carry RoHS compliance. HX 20-P is RoHS compliant. All parts meet environmental regulatory requirements.

Q: What is the frequency response difference between L18P020D15 and HX 20-P?

A: The L18P020D15 operates across DC to 100kHz frequency range. The HX 20-P operates at 50kHz maximum frequency. For applications requiring full DC to 100kHz response, the L18P020D15 or L18P020D15-OP must be used. The HX 20-P is limited to 50kHz applications.

Q: Can supply voltage differences affect substitution?

A: The L18P020D15 requires fixed ±15V supply. The L18P020D15-OP accepts ±12V to ±15V supply range, providing greater flexibility. Both HX 20-P and all lower-rated Tamura parts require ±15V supply. Verify circuit supply voltage compatibility before substitution.
