Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AH3367Q-P-B is determined by the following critical parameters:

Core Functional Requirements:

• Unipolar Hall effect switch technology
• South pole polarization
• Open drain output configuration
• 3V to 28V supply voltage compatibility
• 60mA maximum output current capability
• Automotive-grade qualification (AEC-Q100)
• 3-SIP through-hole package format

Sensing Characteristics: The AH3367Q-P-B operates with a trip threshold of 11.5mT and release threshold of 9mT. Substitute parts must maintain compatible sensing ranges to ensure equivalent magnetic field detection performance in the target application.

Environmental Specifications: Operating temperature range of -40°C to 150°C and automotive-grade classification are mandatory for substitution in automotive applications.

The AH3327Q-P-B qualifies as a manufacturer-recommended substitute, meeting all core functional and electrical requirements while maintaining automotive compliance and package compatibility.

Parameter Comparison

Engineering Selection Recommendations

The AH3327Q-P-B is the manufacturer-recommended substitute for the AH3367Q-P-B. Both components are manufactured by Diodes Incorporated and maintain identical electrical specifications for supply voltage, output current, and operating temperature range. Both are automotive-grade with AEC-Q100 qualification and ROHS3 compliance.

The primary difference lies in sensing threshold characteristics: the AH3327Q-P-B operates at 14mT trip and 7mT release compared to the AH3367Q-P-B's 11.5mT trip and 9mT release. The AH3327Q-P-B additionally features temperature compensation, which enhances sensing stability across the full operating temperature range.

Selection between these parts depends on application-specific magnetic field detection requirements. The AH3327Q-P-B's active product status ensures continued availability, making it the preferred choice for new designs and ongoing production where the sensing threshold difference is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the AH3327Q-P-B directly replace the AH3367Q-P-B in existing designs?

A: Direct replacement is possible from an electrical and mechanical standpoint, as both components share identical package format (3-SIP through hole), supply voltage range (3V–28V), output current capability (60mA), and operating temperature specifications (-40°C to 150°C). However, the sensing thresholds differ: AH3327Q-P-B operates at 14mT trip versus 11.5mT trip for the AH3367Q-P-B. Verify that the application's magnetic field detection requirements are compatible with the higher trip threshold before substitution.

Q: What is the significance of the sensing range difference?

A: The AH3367Q-P-B requires a lower magnetic field strength (11.5mT) to trigger compared to the AH3327Q-P-B (14mT). Applications requiring detection of weaker magnetic fields may not function correctly with the substitute part. Conversely, applications with stronger magnetic fields will operate with either part.

Q: Why does the AH3327Q-P-B include temperature compensation?

A: Temperature compensation adjusts the sensing threshold across the operating temperature range to maintain consistent magnetic field detection performance. This feature enhances reliability in automotive environments where temperature fluctuations are common.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the AH3367Q-P-B and AH3327Q-P-B carry automotive-grade classification with AEC-Q100 qualification, ROHS3 compliance, and identical operating temperature ranges, making them suitable for automotive use.

Q: What is the packaging format for both parts?

A: Both components use 3-SIP (Single In-line Package) through-hole mounting, ensuring mechanical compatibility in existing PCB designs without layout modifications.

Q: Why is the AH3367Q-P-B listed as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing production. The AH3327Q-P-B, with active product status, is the recommended alternative to ensure long-term supply chain continuity.
