HY 25-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HY 25-P is a Hall Effect open-loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 25A sensing range. This component features ratiometric voltage output, single-channel configuration, and through-hole mounting in module form factor.

The HY 25-P carries a "Not For New Designs" product status designation. This status necessitates identification of equivalent substitute parts for ongoing production requirements, maintenance applications, and design continuity where this sensor was previously specified.

Variable Parameter (Substitution Basis):

• Current - Sensing Range: 5A, 10A, 15A, 25A

The HY 25-P can be substituted with HY 10-P, HY 15-P, or HY 5-P. These parts share identical electrical characteristics, frequency response, accuracy specifications, supply voltage requirements, and physical form factor. The current-sensing range is the only differentiating parameter among these components.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts from the HY series must be based on application current requirements and circuit design specifications. All substitute parts listed—HY 15-P, HY 10-P, and HY 5-P—maintain identical electrical performance characteristics, frequency response, accuracy, and compliance certifications as the HY 25-P.

All parts in this substitution group are designated "Not For New Designs" by the manufacturer. This status applies uniformly across HY 25-P, HY 15-P, HY 10-P, and HY 5-P. For new design initiatives, consultation with LEM USA Inc. regarding current-generation Hall Effect sensor alternatives is appropriate.

All substitute parts carry RoHS Compliant status and REACH Unaffected designation, ensuring regulatory compliance for applications subject to these requirements. Moisture Sensitivity Level 1 (Unlimited) applies to all parts, indicating no moisture sensitivity constraints during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can HY 10-P substitute for HY 25-P in all applications?

A: HY 10-P shares identical electrical characteristics, frequency response, accuracy, and supply voltage requirements with HY 25-P. However, HY 10-P has a maximum current-sensing range of 10A, compared to HY 25-P's 25A range. Substitution is valid only when the application current requirement does not exceed 10A.

Q: What is the primary difference between HY 25-P, HY 15-P, HY 10-P, and HY 5-P?

A: The sole differentiating parameter is the current-sensing range. HY 25-P measures up to 25A, HY 15-P up to 15A, HY 10-P up to 10A, and HY 5-P up to 5A. All other specifications—output type, frequency response, accuracy, supply voltage, response time, and physical form factor—are identical.

Q: Are all substitute parts RoHS compliant?

A: Yes. HY 25-P, HY 15-P, HY 10-P, and HY 5-P all carry RoHS Compliant status and REACH Unaffected designation.

Q: What is the mounting configuration for these sensors?

A: All parts in this group feature through-hole mounting in module form factor, packaged in trays. Physical compatibility is maintained across all substitute options.

Q: Why is HY 25-P marked "Not For New Designs"?

A: This designation indicates the manufacturer has classified this product as obsolete or superseded for new design applications. Existing designs using HY 25-P may continue with this part or equivalent substitutes from the HY series. For new applications, contact LEM USA Inc. for current-generation alternatives.

Q: Can HY 5-P be used in place of HY 25-P?

A: HY 5-P is electrically and mechanically compatible with HY 25-P only if the application current requirement does not exceed 5A. The 5A current-sensing range of HY 5-P is the limiting factor for substitution in higher-current applications.

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

A: All parts support DC to 50kHz frequency response, enabling measurement of both DC and AC currents within this bandwidth.

Q: Are there any supply voltage differences between substitute parts?

A: No. All parts require ±12V to ±15V supply voltage. Supply voltage specifications are identical across HY 25-P, HY 15-P, HY 10-P, and HY 5-P.
