Key Parameters

Substitute Part Grouping Explanation

Substitution of the HX 20-P is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Sensor Type: Hall Effect, Open Loop
• Measurement Capability: AC/DC bidirectional current measurement
• Output Configuration: Ratiometric voltage output
• Supply Voltage: ±15V
• Frequency Response: 50kHz
• Linearity: ±1%
• Accuracy: ±1%
• Response Time: 3µs
• Current Supply (Max): 15mA
• Operating Temperature Range: -25°C to 85°C
• Mounting Type: Through Hole
• Package Type: Module
• Compliance: RoHS Compliant, REACH Unaffected

Current Sensing Range Consideration: The HX 20-P operates within the LEM HX series family. Substitute parts within this series maintain identical electrical specifications and physical form factors. The current sensing range (20A) is the primary differentiating parameter within the HX series. Lower-rated current sensors (HX 03-P, HX 05-P, HX 10-P, HX 15-P) are parametrically equivalent and share all core electrical and mechanical characteristics with the HX 20-P.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: All parts in the HX series, including HX 20-P, HX 15-P, HX 10-P, HX 05-P, and HX 03-P, carry the designation "Not For New Designs." This status indicates these components have reached end-of-life in the manufacturer's active product development cycle. Organizations currently utilizing HX 20-P in production must select substitute parts from the available HX series inventory to maintain operational continuity.

Compliance and Certification: All substitute parts maintain identical compliance certifications:

• RoHS Compliant
• REACH Unaffected
• ECCN Classification: EAR99
• HTSUS Code: 9030.33.3800

These certifications ensure regulatory equivalence across all substitute selections.

Current Sensing Range Selection: Selection of substitute parts depends on application current requirements. The HX 20-P is rated for 20A maximum current sensing. Substitute parts with lower current ratings (HX 15-P at 15A, HX 10-P at 10A, HX 05-P at 5A, HX 03-P at 3A) are electrically and mechanically equivalent but operate within reduced current measurement ranges. Applications requiring measurement of currents exceeding the substitute part's rated range are not suitable for lower-rated alternatives.

Inventory Availability: Current inventory status for substitute parts:

• HX 03-P: 1,961 units
• HX 05-P: 1,567 units
• HX 10-P: 1,433 units
• HX 15-P: 1,049 units

Frequently Asked Questions (FAQ)

Q: Can HX 15-P, HX 10-P, HX 05-P, or HX 03-P be used as direct replacements for HX 20-P?

A: These parts are parametrically equivalent in all electrical and mechanical specifications. Direct substitution is determined by application current requirements. If your application measures currents up to 15A, HX 15-P is electrically and mechanically compatible. If currents exceed the substitute part's rating, that part is not suitable.

Q: What is the primary difference between HX 20-P and the substitute parts?

A: The current sensing range is the only differentiating parameter. All parts share identical sensor type (Hall Effect, Open Loop), output configuration (Ratiometric Voltage), supply voltage (±15V), frequency response (50kHz), accuracy (±1%), linearity (±1%), response time (3µs), operating temperature range (-25°C to 85°C), mounting type (Through Hole), and package type (Module).

Q: Are the physical dimensions and pin configurations identical across all HX series parts?

A: All HX series parts are Through Hole Module packages with identical mounting specifications. The provided parameters confirm matching package types and mounting configurations across HX 20-P, HX 15-P, HX 10-P, HX 05-P, and HX 03-P.

Q: Do all substitute parts meet the same regulatory requirements as HX 20-P?

A: Yes. All substitute parts carry identical compliance certifications: RoHS Compliant, REACH Unaffected, ECCN EAR99, and HTSUS 9030.33.3800.

Q: What is the significance of the "Not For New Designs" status?

A: This designation indicates the HX series has reached end-of-life in the manufacturer's product portfolio. No new product development should incorporate these components. Existing applications using HX 20-P must transition to available substitute inventory or identify alternative current sensor solutions from the manufacturer's active product lines.

Q: Can HX 20-P be substituted with parts rated for higher current sensing?

A: The provided substitute list includes only lower-rated current sensors (HX 15-P, HX 10-P, HX 05-P, HX 03-P). No higher-rated alternatives are documented in this reference. Applications requiring current sensing above 20A require evaluation of alternative sensor solutions outside the HX series.

Q: What is the maximum current that can be safely measured with each substitute part?

A: HX 15-P: 15A maximum; HX 10-P: 10A maximum; HX 05-P: 5A maximum; HX 03-P: 3A maximum. Operating these sensors at currents exceeding their rated range may result in measurement inaccuracy or component damage.
