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

Part Overview

The HO 25-P is an active Hall Effect open-loop current sensor manufactured by LEM USA Inc., designed for bidirectional AC/DC current measurement applications. This single-channel module features a 25A sensing range with ratiometric voltage output and operates across industrial temperature ranges. The part maintains Active product status with full RoHS compliance and REACH unaffected classification.

Substitute parts are necessary when application requirements differ in current-sensing range, supply voltage compatibility, or when inventory constraints require alternative configurations within the HO-P series family.

Key Parameters

Substitute Part Grouping Explanation

Substitution within the HO-P series is determined by the following critical parameters:

Current-Sensing Range: The HO 25-P operates at 25A maximum. Substitute parts HO 10-P and HO 6-P/SP33 provide reduced current ranges (10A and 6A respectively) and are suitable only when application current requirements do not exceed their respective ratings.

Supply Voltage: The HO 25-P requires 5V supply. Substitute parts designated with /SP33 suffix (HO 25-P/SP33, HO 10-P/SP33, HO 6-P/SP33) operate at 3.3V supply voltage. These are direct substitutes only when the application circuit supports 3.3V logic levels.

Series Compatibility: All parts belong to the HO-P series family, sharing identical sensor topology, frequency response (DC ~ 250kHz), linearity (±0.5%), accuracy (±1.4%), response time (3.5µs), operating temperature range (-40°C ~ 105°C), bidirectional polarization, and through-hole mounting configuration.

Compliance & Packaging: All substitute parts maintain RoHS compliance, REACH unaffected status, and identical tray packaging. Moisture sensitivity differs: HO 25-P carries MSL 1 (Unlimited), while /SP33 variants are Not Applicable.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Current Range, 5V Supply) HO 25-P has no direct equivalent within the provided substitute list that maintains both 25A current sensing and 5V supply voltage.

Equivalent with Supply Voltage Modification (Same Current Range, 3.3V Supply) HO 25-P/SP33 provides identical 25A current-sensing capability with 3.3V supply operation. Selection of this part requires circuit redesign to accommodate 3.3V logic levels. Both parts maintain Active product status, RoHS compliance, and REACH unaffected classification.

Reduced Current Range Substitutes (5V Supply) HO 10-P operates at 10A maximum current sensing with 5V supply, maintaining identical frequency response, accuracy, and response time specifications. This part is suitable only when application current requirements do not exceed 10A.

Reduced Current Range Substitutes (3.3V Supply) HO 10-P/SP33 and HO 6-P/SP33 provide 10A and 6A current-sensing ranges respectively with 3.3V supply operation. These parts require both current range verification and circuit redesign for 3.3V compatibility.

All substitute parts maintain Active product status and full regulatory compliance (RoHS, REACH, ECCN EAR99, HTSUS 9030.33.3800).

Frequently Asked Questions (FAQ)

Q: Can HO 25-P be replaced with HO 10-P in a 25A application? A: No. HO 10-P has a maximum current-sensing range of 10A. Using this part in a 25A application will result in sensor saturation and measurement error. Current range must not exceed the part's rated specification.

Q: What is the primary difference between HO 25-P and HO 25-P/SP33? A: The primary difference is supply voltage. HO 25-P requires 5V supply, while HO 25-P/SP33 operates at 3.3V supply. Both maintain identical 25A current-sensing range, frequency response, accuracy, and response time. Selection depends on circuit supply voltage availability.

Q: Are /SP33 suffix parts compatible with 5V supply circuits? A: No. Parts designated with /SP33 suffix are specified for 3.3V supply operation. Operating these parts at 5V supply violates manufacturer specifications and may cause component damage or measurement errors.

Q: Can HO 10-P/SP33 substitute for HO 25-P in a 3.3V circuit? A: No. While HO 10-P/SP33 operates at 3.3V supply, its maximum current-sensing range is 10A. This part is suitable only when application current requirements do not exceed 10A. For 25A measurement at 3.3V supply, use HO 25-P/SP33.

Q: Do all HO-P series parts share identical mounting and package specifications? A: Yes. All parts in the HO-P series (HO 25-P, HO 10-P, HO 6-P/SP33, and their /SP33 variants) feature through-hole mounting, single pass-through module package configuration, and tray packaging. Physical mounting compatibility is maintained across all variants.

Q: What is the significance of MSL rating differences between HO 25-P and /SP33 variants? A: HO 25-P carries MSL 1 (Unlimited) moisture sensitivity level, indicating no moisture sensitivity restrictions. /SP33 variants carry MSL Not Applicable classification. This difference does not affect functional performance but may impact storage and handling procedures according to IPC standards.

Q: Are all substitute parts currently in active production? A: Yes. All parts listed (HO 25-P, HO 10-P, HO 10-P/SP33, HO 25-P/SP33, HO 6-P/SP33) maintain Active product status with LEM USA Inc., indicating current production and availability.
