Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: HAS 50-S

The HAS 50-S is the qualified substitute for the HASS 50-S based on functional equivalence across all critical measurement parameters. Both components are manufactured by LEM USA Inc. and share identical core specifications for current sensing, sensor technology, output configuration, and frequency response.

Key Considerations for Implementation:

1. Supply Voltage Difference: The HASS 50-S operates on 5V single supply, while the HAS 50-S requires ±15V dual supply. Circuit redesign is necessary to accommodate this voltage requirement change. Power supply architecture must be evaluated and modified accordingly.

2. Operating Temperature Range: The HAS 50-S operates across -10°C ~ 80°C, which is narrower than the HASS 50-S range of -40°C ~ 85°C. Applications requiring operation below -10°C or above 80°C must be assessed for compatibility.

3. Product Status: The HAS 50-S carries "Active" product status, ensuring ongoing manufacturer support, availability, and continued compliance with regulatory requirements. The HASS 50-S "Not For New Designs" status confirms the necessity of transition to the HAS 50-S for sustained production.

4. Regulatory Compliance: Both components maintain RoHS Compliance and REACH Unaffected status, satisfying environmental and regulatory requirements for equivalent implementation.

5. Performance Specifications: Linearity specification of the HAS 50-S (±1%) is within acceptable engineering tolerance relative to the HASS 50-S (±0.5%). Current supply consumption of the HAS 50-S (15mA maximum) is lower than the HASS 50-S (19mA maximum), providing improved power efficiency.

Frequently Asked Questions (FAQ)

Q: Can the HAS 50-S directly replace the HASS 50-S without circuit modifications?

A: No. While the HAS 50-S is functionally equivalent for current measurement, the supply voltage requirement differs significantly. The HASS 50-S operates on 5V single supply, whereas the HAS 50-S requires ±15V dual supply. Circuit redesign is mandatory to accommodate this voltage architecture change.

Q: What is the impact of the different operating temperature ranges?

A: The HAS 50-S operates across -10°C ~ 80°C, compared to the HASS 50-S range of -40°C ~ 85°C. Applications requiring operation below -10°C or above 80°C must be evaluated for compatibility. If extended low-temperature operation below -10°C is required, alternative components must be considered.

Q: Are both components physically compatible in terms of mounting?

A: Yes. Both the HASS 50-S and HAS 50-S utilize Through Hole mounting type and Module package configuration, ensuring physical compatibility at the board level. However, circuit layout modifications may be necessary to accommodate the different supply voltage requirements.

Q: What is the significance of the "Not For New Designs" status on the HASS 50-S?

A: This status indicates that LEM USA Inc. has discontinued active development and support for the HASS 50-S. The manufacturer recommends transitioning to alternative components for new applications. The HAS 50-S, with "Active" product status, is the recommended successor component.

Q: How do the accuracy and linearity specifications compare?

A: Both components maintain ±1% accuracy. The HASS 50-S specifies ±0.5% linearity, while the HAS 50-S specifies ±1% linearity. This difference is within acceptable engineering tolerance for most current measurement applications. System-level accuracy requirements should be evaluated to confirm acceptability.

Q: Are there any regulatory compliance differences between the two components?

A: No. Both the HASS 50-S and HAS 50-S are RoHS Compliant and REACH Unaffected, satisfying equivalent environmental and regulatory requirements for implementation in compliant applications.

Q: What is the impact of the different maximum supply currents?

A: The HAS 50-S draws a maximum of 15mA compared to the HASS 50-S at 19mA. This represents improved power efficiency with the substitute component. Power supply design should account for this lower current requirement.
