HAS 300-P Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HAS 300-P is a Hall Effect open-loop bidirectional current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications up to 300A. This module provides ratiometric voltage output with ±1% linearity and accuracy across a frequency range of DC to 50kHz. The part is classified as Active product status and is RoHS Compliant with REACH Unaffected designation.

Substitute parts are identified when applications require alternative current-sensing ranges, packaging variants, or when the primary part reaches end-of-life status. The HAS series provides multiple current ratings (50A, 100A, 200A, 300A) and packaging options (Tray variants designated -P and -S) to accommodate diverse system requirements.

Substitute Part Grouping Explanation

Substitute parts within the HAS series are qualified based on the following criteria:

Electrical Parameter Compatibility: All substitute parts maintain identical electrical specifications across sensor type (Hall Effect, Open Loop), measurement capability (AC/DC), output configuration (Ratiometric Voltage), frequency response (DC ~ 50kHz), linearity (±1%), accuracy (±1%), supply voltage (±15V), response time (3µs), and maximum supply current (15mA).

Current Sensing Range: Substitute parts are available in four current ratings: 50A, 100A, 200A, and 300A. Selection depends on the application's maximum current measurement requirement. The HAS 300-P is substitutable with HAS 300-S (same 300A rating, different packaging variant).

Packaging Variants: The HAS series uses two packaging designations: -P (Tray packaging with MSL 1 Unlimited) and -S (Tray packaging with MSL Not Applicable). These represent different manufacturing or supply chain variants of the same electrical module.

Operating Conditions: All parts operate across -10°C to 80°C temperature range with bidirectional polarization capability and through-hole mounting configuration.

Compliance and Status: All substitute parts are RoHS Compliant and REACH Unaffected. Product status varies: HAS 50-P is marked "Not For New Designs," while HAS 100-P, HAS 100-S, HAS 200-S, HAS 300-S, and HAS 50-S are Active status.

Engineering Selection Recommendations

Direct Equivalent (Same Current Rating): HAS 300-S is the direct equivalent to HAS 300-P. Both parts provide 300A current sensing with identical electrical and mechanical specifications. Selection between these variants depends on packaging and moisture sensitivity requirements. HAS 300-P carries MSL 1 (Unlimited) designation, while HAS 300-S carries MSL Not Applicable. Both are Active status products suitable for new designs.

Lower Current Rating Alternatives: HAS 200-S, HAS 100-P, HAS 100-S, HAS 50-P, and HAS 50-S are available for applications requiring reduced current measurement ranges. These parts maintain all electrical performance characteristics of the HAS 300-P but are limited to their respective current ratings (200A, 100A, 50A). Selection of lower-rated parts is appropriate only when the application's maximum current requirement does not exceed the part's rating.

Product Status Considerations: HAS 50-P is designated "Not For New Designs" and should not be selected for new product development. For 50A applications, HAS 50-S is the recommended Active status alternative. All other substitute parts carry Active status and are suitable for new designs.

Compliance Verification: All listed substitute parts maintain RoHS Compliance and REACH Unaffected status, matching the HAS 300-P compliance profile. No additional regulatory assessment is required when substituting within this part family.

Frequently Asked Questions (FAQ)

Q: Can HAS 300-S replace HAS 300-P in existing designs? A: Yes. HAS 300-S is electrically and mechanically equivalent to HAS 300-P. Both provide 300A current sensing with identical performance specifications. The primary difference is the moisture sensitivity level designation. Substitution is direct for applications where MSL Not Applicable is acceptable.

Q: What is the difference between -P and -S packaging variants? A: The -P variant carries MSL 1 (Unlimited) designation, while the -S variant carries MSL Not Applicable. Both use Tray packaging format. The designation reflects different moisture sensitivity classifications applicable to storage and handling conditions. Electrical and mechanical performance are identical.

Q: Can a lower-rated part (HAS 200-S, HAS 100-P) substitute for HAS 300-P? A: Lower-rated parts can substitute only if the application's maximum current requirement does not exceed the substitute part's rating. HAS 200-S is limited to 200A measurement, HAS 100-P and HAS 100-S to 100A, and HAS 50-P and HAS 50-S to 50A. Using an undersized part will result in measurement saturation and inaccuracy above the part's rated current.

Q: Why is HAS 50-P marked "Not For New Designs"? A: HAS 50-P carries "Not For New Designs" product status, indicating it is in end-of-life phase. For new product development requiring 50A current sensing, HAS 50-S is the recommended Active status alternative with identical electrical specifications.

Q: Are all HAS series parts compatible with the same PCB footprint? A: All HAS series parts use identical Through Hole mounting configuration and Module package type. PCB footprint compatibility is maintained across all current ratings and packaging variants within the HAS family.

Q: What are the key electrical parameters that remain constant across all HAS substitutes? A: All HAS series parts maintain: Hall Effect open-loop sensor type, AC/DC measurement capability, ratiometric voltage output, DC to 50kHz frequency response, ±1% linearity, ±1% accuracy, ±15V supply voltage, 3µs response time, 15mA maximum supply current, -10°C to 80°C operating temperature, bidirectional polarization, and RoHS Compliance.

Q: Can HAS 300-P be used in applications requiring higher current measurement? A: No. HAS 300-P is rated for maximum 300A current sensing. Applications requiring measurement above 300A require alternative sensor solutions outside the HAS series.

Q: What inventory status should influence part selection? A: Inventory levels are provided for reference but do not affect electrical or mechanical substitution criteria. Part selection should be based on electrical requirements, current rating, product status, and compliance certifications. Inventory availability should be confirmed with the supplier for procurement planning.
