• Maximum supply current: 4mA
• Operating temperature range: -40°C ~ 150°C

Mechanical Compatibility Requirements:

• Package type: SOT-23-3
• Mounting type: Surface Mount
• Polarization: South Pole
• Technology: Hall Effect unipolar switch function

Regulatory & Compliance Requirements:

• RoHS3 compliance
• Automotive grade qualification

The AH3328Q-SA-7 meets all mandatory electrical, mechanical, and regulatory criteria for direct substitution. Sensing range parameters differ between the main part and substitute, but both devices operate within the same supply voltage and output specifications, allowing functional equivalence in applications where the specific trip and release thresholds are compatible with system design requirements.

Parameter Comparison

Engineering Selection Recommendations

The AH3328Q-SA-7 is the manufacturer-recommended substitute for the AH3368Q-SA-7. Both devices share identical electrical specifications, package configuration, and regulatory compliance status. The AH3328Q-SA-7 maintains Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the AH3368Q-SA-7.

Selection between these parts should be based on application-specific sensing range requirements. The AH3368Q-SA-7 operates with a 15mT trip threshold and 12.5mT release threshold, while the AH3328Q-SA-7 operates with an 18mT trip threshold and 10.5mT release threshold. Both devices are AEC-Q100 qualified and suitable for automotive applications requiring unipolar Hall effect switching in the SOT-23-3 package.

Frequently Asked Questions (FAQ)

Q: Can the AH3328Q-SA-7 be used as a direct replacement for the AH3368Q-SA-7?

A: Yes, the AH3328Q-SA-7 is the manufacturer-recommended substitute. Both devices share identical supply voltage ranges (3V ~ 28V), output type (open drain), maximum output current (60mA), package configuration (SOT-23-3), and operating temperature range (-40°C ~ 150°C). The primary difference is the sensing range threshold, which must be evaluated against specific application requirements.

Q: What is the difference in sensing range between these two parts?

A: The AH3368Q-SA-7 has a trip threshold of 15mT and release threshold of 12.5mT. The AH3328Q-SA-7 has a trip threshold of 18mT and release threshold of 10.5mT. Applications requiring the specific 15mT trip point should confirm compatibility with the 18mT threshold of the substitute before implementation.

Q: Are both parts qualified for automotive applications?

A: Yes, both the AH3368Q-SA-7 and AH3328Q-SA-7 are AEC-Q100 qualified and automotive grade, meeting automotive industry reliability and qualification standards.

Q: Is the SOT-23-3 package identical between both parts?

A: Yes, both parts use the SOT-23-3 package (also designated TO-236-3 or SC-59), ensuring mechanical and electrical compatibility on the same PCB footprint.

Q: Why is the AH3368Q-SA-7 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. The AH3328Q-SA-7, which maintains Active status, is the recommended path forward for new designs and ongoing procurement.
