HY 20-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HY 20-P is a Hall Effect open-loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 20A sensing range. This component features ratiometric voltage output, single-channel configuration, and through-hole mounting in module form factor.

The HY 20-P carries a "Not For New Designs" product status designation. This status indicates the component is in mature or end-of-life phase. Organizations developing new applications or redesigning existing systems should evaluate equivalent substitute parts from the HY series that maintain functional compatibility while ensuring long-term supply chain viability and design continuity.

Variable Parameter (Substitution Basis):

• Current Sensing Range: 5A, 10A, 15A, or 20A

The HY series substitutes are differentiated solely by current sensing capacity. Selection of an appropriate substitute depends on the maximum current measurement requirement of the target application. All substitute parts maintain identical electrical performance characteristics, interface specifications, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: All parts in this substitution group, including the HY 20-P and its equivalents (HY 15-P, HY 10-P, HY 5-P), carry "Not For New Designs" designation. This status applies uniformly across the HY series. Organizations initiating new product development should evaluate these components as interim solutions only, with awareness of potential long-term availability constraints.

Compliance and Certification: All substitute parts maintain identical regulatory compliance profiles:

• RoHS Compliant certification
• REACH Unaffected status
• EAR99 export classification
• HTSUS code 9030.33.3800

These certifications are consistent across all current sensing ratings within the HY series, ensuring equivalent regulatory standing for any substitution selection.

Selection Basis: Choose the substitute part based on the maximum AC/DC current measurement requirement of the application circuit. The HY 20-P is appropriate for applications requiring measurement of currents up to 20A. If the application maximum current does not exceed 15A, 10A, or 5A respectively, the HY 15-P, HY 10-P, or HY 5-P may be selected. All selected parts deliver identical output signal characteristics, frequency response, accuracy, and environmental performance within their respective current ranges.

Frequently Asked Questions (FAQ)

Q: Can the HY 10-P substitute for the HY 20-P in all applications?

A: The HY 10-P is a functional substitute only for applications where the maximum measured current does not exceed 10A. If the application circuit requires measurement of currents between 10A and 20A, the HY 10-P will not provide adequate measurement range. All other electrical and mechanical parameters are identical between these parts.

Q: Are there any differences in output signal characteristics between HY series current sensors?

A: No. All HY series sensors (HY 5-P, HY 10-P, HY 15-P, HY 20-P) deliver identical ratiometric voltage output, frequency response (DC ~ 50kHz), linearity (±1%), accuracy (±1%), response time (3µs), and supply voltage requirements (±12V ~ 15V). The only difference is the maximum current sensing range.

Q: Can I use the HY 5-P in place of the HY 20-P?

A: The HY 5-P is a functional substitute only for applications where the maximum measured current does not exceed 5A. The HY 5-P will saturate and provide inaccurate measurements if exposed to currents exceeding its 5A sensing range. All other performance characteristics are identical.

Q: Are the mounting and package specifications identical across all HY series substitutes?

A: Yes. All HY series current sensors use through-hole mounting, module package type, and tray packaging format. PCB layout and mechanical integration are identical across all current sensing ratings.

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

A: This designation indicates the HY series is in mature or end-of-life phase. While these components remain available and fully functional, manufacturers may discontinue production or reduce inventory support over time. New product development should consider this status when selecting components for long-term production commitments.

Q: Do all HY series substitutes have the same environmental operating range?

A: Yes. All HY series sensors operate across the identical temperature range of -10°C to 80°C and maintain the same moisture sensitivity level (MSL 1, Unlimited). Environmental performance is consistent across all current sensing ratings.

Q: Are there supply voltage differences between substitute parts?

A: No. All HY series current sensors require identical supply voltage of ±12V ~ 15V and draw a maximum of 10mA supply current. Power supply specifications are uniform across all current sensing ratings.
