Key Parameters

Substitute Part Grouping Explanation

Substitution of the AH3363Q-SA-7 is determined by the following critical parameters:

• Identical function classification: Unipolar Switch
• Matching technology: Hall Effect sensor
• Identical output configuration: Open Drain
• Compatible package: SOT-23-3 surface mount
• Overlapping supply voltage range: 3V to 28V
• Matching polarization: South Pole detection
• Equivalent current ratings: 4mA supply, 60mA output maximum
• Compatible temperature range: -40°C to 150°C

The AH3323Q-SA-7 meets all these criteria and is classified as a manufacturer-recommended substitute. Differences in sensing range thresholds (trip and release points) do not preclude substitution when application requirements permit tolerance variation within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The AH3323Q-SA-7 is the manufacturer-recommended substitute for the AH3363Q-SA-7. Both components share identical electrical and mechanical specifications across all critical parameters: function, technology, package, output type, voltage range, and current ratings.

The primary distinction is the sensing range threshold variation. The AH3363Q-SA-7 specifies 5.5mT trip and 4.6mT release, while the AH3323Q-SA-7 specifies 7.2mT trip and 2mT release. Selection between these parts depends on application-specific magnetic field detection requirements.

The AH3323Q-SA-7 carries Active product status, ensuring continued availability and supply chain support. Both parts maintain ROHS3 compliance and are suitable for surface mount assembly in automotive and industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the AH3323Q-SA-7 directly replace the AH3363Q-SA-7 in existing designs?

A: Direct pin-for-pin and functional replacement is possible. Both components use identical SOT-23-3 packaging, open drain output configuration, and electrical operating parameters. Verification of sensing range compatibility with application requirements is necessary before implementation.

Q: What is the primary difference between these two parts?

A: The sensing range thresholds differ. The AH3363Q-SA-7 operates at 5.5mT trip and 4.6mT release, while the AH3323Q-SA-7 operates at 7.2mT trip and 2mT release. All other electrical and mechanical characteristics are identical.

Q: Why is the AH3363Q-SA-7 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. The AH3323Q-SA-7 is the active replacement offering equivalent functionality with continued production support.

Q: Are there temperature or voltage compatibility concerns?

A: No. Both parts operate across the identical temperature range (-40°C to 150°C) and supply voltage range (3V to 28V), ensuring thermal and electrical compatibility in equivalent applications.

Q: Does the AH3323Q-SA-7 include temperature compensation?

A: Yes. The AH3323Q-SA-7 includes temperature compensation as a specified feature, which may provide improved stability across the operating temperature range compared to the main part.

Q: What packaging formats are available for these parts?

A: Both the AH3363Q-SA-7 and AH3323Q-SA-7 are supplied in Tape & Reel (TR) format for automated assembly. The physical package is SOT-23-3, also designated as TO-236-3 or SC-59.
