HAS 500-P Hall Effect Current Sensor - Equivalent & Substitute Parts

Part Overview

The HAS 500-P is a Hall Effect open-loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications up to 500A. This component operates with ratiometric voltage output, ±15V supply voltage, and maintains ±1% linearity and accuracy across a DC to 50kHz frequency range.

The HAS 500-P carries an Obsolete product status. Identification of equivalent and substitute parts is necessary for design continuity, procurement planning, and system integration in applications where the 500A sensing capability is required or where lower current-rated alternatives meet application requirements.

Output: Ratiometric, Voltage
Frequency Range: DC ~ 50kHz
Linearity: ±1%
Accuracy: ±1%
Voltage - Supply: ±15V
Response Time: 3µs

Variable Parameter (Determines Substitution Scope):

Current - Sensing: 50A, 100A, 200A, 300A, 400A, 500A

The HAS series current sensors are interchangeable within the same electrical and mechanical specifications. Substitution is valid when the application current requirement does not exceed the rated sensing capacity of the substitute part. Lower-rated sensors (50A, 100A, 200A, 300A, 400A) function as substitutes for the 500A model when application current demands permit.

Packaging variants exist within the series: "-P" suffix denotes Tray packaging, while "-S" suffix also denotes Tray packaging. Both packaging types maintain identical electrical and mechanical characteristics.

Engineering Selection Recommendations

Primary Substitute for New Designs:

For applications requiring 500A sensing capability with active product status, no direct equivalent exists within the provided HAS series. The HAS 500-P is obsolete with no active-status replacement at the 500A rating.

Alternative Selection Based on Application Current Requirements:

When application current demands permit operation below 500A, the following active-status substitutes are available:

HAS 400-S: Active status, 400A sensing capacity. Suitable for applications with maximum current requirements up to 400A.
HAS 300-S: Active status, 300A sensing capacity. Suitable for applications with maximum current requirements up to 300A.
HAS 200-S: Active status, 200A sensing capacity. Suitable for applications with maximum current requirements up to 200A.
HAS 100-S: Active status, 100A sensing capacity. Suitable for applications with maximum current requirements up to 100A.
HAS 50-S: Active status, 50A sensing capacity. Suitable for applications with maximum current requirements up to 50A.

All listed substitutes maintain identical electrical specifications (±15V supply, ±1% linearity/accuracy, 3µs response time, DC to 50kHz frequency range) and mechanical characteristics (through-hole mounting, module package) as the HAS 500-P.

Compliance Considerations:

All substitute parts carry RoHS Compliant status and REACH Unaffected designation, matching the regulatory compliance profile of the HAS 500-P. ECCN classification (EAR99) and HTSUS code (9030.33.3800) remain consistent across the series.

Product Status Implications:

Parts designated "Not For New Designs" (HAS 50-P, HAS 400-P) are available for existing system support and legacy applications but should not be selected for new product development. Active-status parts (HAS 50-S, HAS 100-S, HAS 200-S, HAS 300-S, HAS 400-S) are recommended for new designs requiring current sensing within their respective ratings.

Frequently Asked Questions (FAQ)

Q: Can the HAS 500-P be directly replaced with an active-status part?

A: No direct replacement exists. The HAS 500-P is obsolete with no active-status equivalent at 500A. Substitution requires selection of a lower-rated sensor from the HAS series if application current demands permit.

Q: What determines whether a lower-rated HAS sensor can substitute for the HAS 500-P?

A: The maximum current flowing through the application circuit. A substitute sensor must have a current-sensing rating equal to or greater than the peak current the application will draw. For example, if an application draws maximum 300A, the HAS 300-S is suitable; if it draws 350A, the HAS 400-S is required.

Q: Are the "-P" and "-S" suffix variants electrically identical?

A: Yes. Both "-P" and "-S" variants within the same current rating (e.g., HAS 100-P and HAS 100-S) maintain identical electrical and mechanical specifications. The suffix indicates packaging designation (Tray for both), with "-S" variants carrying Active product status while some "-P" variants are obsolete or not recommended for new designs.

Q: Do all HAS series sensors operate with the same supply voltage?

A: Yes. All HAS series current sensors in this family operate with ±15V supply voltage, enabling direct substitution from a power supply perspective.

Q: What is the frequency response limitation for these sensors?

A: All HAS series sensors operate across DC to 50kHz frequency range. Applications requiring current measurement beyond 50kHz require alternative sensor families outside the HAS series.

Q: Are there any differences in response time across the HAS series?

A: No. All HAS series sensors maintain 3µs response time regardless of current rating, ensuring consistent transient response characteristics across substitutions.

Q: Can the HAS 500-P be used in applications requiring lower current measurement?

A: Yes, the HAS 500-P can measure currents below 500A. However, measurement resolution and accuracy may be suboptimal at very low current levels. For applications with known maximum current requirements significantly below 500A, a lower-rated sensor provides better measurement resolution within its operating range.

Q: What is the operating temperature range for all HAS series sensors?

A: All HAS series sensors operate across -10°C to 80°C. This range is consistent across all current ratings and variants, enabling substitution without thermal performance concerns.

Q: Are all HAS series sensors bidirectional?

A: Yes. All HAS series sensors feature bidirectional polarization, enabling measurement of current flow in both directions without modification.

Q: What mounting considerations apply when substituting HAS sensors?

A: All HAS series sensors use through-hole mounting in module packages. Physical dimensions may vary by current rating; verify mechanical compatibility with PCB layout and enclosure design before substitution.
