HASS 300-S Hall Effect Current Sensor Equivalent & Substitute Parts

Part Overview

The HASS 300-S is a Hall Effect current sensor manufactured by LEM USA Inc., designed for AC/DC current measurement applications with a 300A sensing range. This component operates as an open-loop, bidirectional module with ratiometric voltage output. The part carries a "Not For New Designs" product status, indicating it has been superseded in LEM's current product portfolio. When the HASS 300-S is unavailable or when design flexibility permits, identifying equivalent substitute parts becomes necessary to maintain supply chain continuity and project timelines.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HASS 300-S is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Sensor technology: Hall Effect, Open Loop architecture
• Output configuration: Ratiometric voltage output
• Supply voltage: 5V
• Frequency response: DC ~ 50kHz minimum
• Linearity tolerance: ±0.5%
• Accuracy specification: ±1%
• Response time: 3µs
• Operating temperature range: -40°C ~ 85°C minimum
• Polarization: Bidirectional capability
• Mounting: Through Hole
• Package type: Module format
• Regulatory compliance: RoHS Compliant, REACH Unaffected

Flexible Parameter:

• Current sensing range: May be lower than 300A if application requirements permit

The HASS 200-S qualifies as a parametric equivalent substitute because it maintains all mandatory matching parameters while offering a reduced current sensing range of 200A instead of 300A. This substitution is valid only for applications where the maximum current measurement requirement does not exceed 200A.

Engineering Selection Recommendations

HASS 300-S Selection Criteria: The HASS 300-S remains the primary choice for applications requiring current measurement up to 300A with the specified performance characteristics. However, due to its "Not For New Designs" status, this part should not be selected for new product development initiatives.

HASS 200-S Selection Criteria: The HASS 200-S is a valid substitute for the HASS 300-S when the application's maximum current measurement requirement does not exceed 200A. Both parts maintain identical electrical performance, frequency response, accuracy, and thermal operating range. The HASS 200-S carries the same regulatory compliance certifications (RoHS Compliant, REACH Unaffected) and identical mechanical mounting specifications.

Compliance Considerations: Both parts are RoHS Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution. The identical supply voltage (5V), response time (3µs), and output configuration ensure direct functional compatibility in circuit designs.

Inventory and Availability: The HASS 200-S maintains higher inventory availability (9100 Pcs) compared to the HASS 300-S (6728 Pcs), supporting supply chain continuity for applications within the 200A current range.

Frequently Asked Questions (FAQ)

Q: Can the HASS 200-S replace the HASS 300-S in all applications?

A: The HASS 200-S can replace the HASS 300-S only in applications where the maximum current measurement requirement does not exceed 200A. All other electrical and mechanical parameters are identical, ensuring functional compatibility within this current limitation.

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

A: This status indicates that LEM USA Inc. has superseded the HASS 300-S in their current product portfolio. New product development should not incorporate this part. Existing designs may continue using available inventory, and the HASS 200-S serves as an alternative for applications within its current range.

Q: Are the mounting and packaging specifications identical between these parts?

A: Yes. Both the HASS 300-S and HASS 200-S use Through Hole mounting, Module package type, and Tray packaging format. No PCB layout or mechanical assembly modifications are required when substituting between these parts.

Q: Do these sensors have identical output characteristics?

A: Yes. Both parts provide ratiometric voltage output with identical linearity (±0.5%), accuracy (±1%), and response time (3µs). The output signal conditioning and interface requirements are identical.

Q: What is the frequency response capability of the HASS 200-S?

A: The HASS 200-S maintains the same frequency response as the HASS 300-S: DC ~ 50kHz. This bandwidth supports both AC and DC current measurement applications within this frequency range.

Q: Are there any thermal operating differences between these parts?

A: No. Both parts operate across the identical temperature range of -40°C ~ 85°C with the same thermal specifications and performance characteristics.

Q: What supply voltage is required for both sensors?

A: Both the HASS 300-S and HASS 200-S require a 5V supply voltage with maximum supply current of 19mA.
