Substitute Part Grouping Explanation

The HAL1565 SU-A serves as the manufacturer-recommended substitute for the HAL566 SF-E. Substitution is based on the following critical parameters:

• Functional Category: Both components are digital magnetic switches within the HAL® sensor family from TDK-Micronas GmbH
• Application Type: Both function as Hall Effect sensors for magnetic field detection
• Output Configuration: Both provide digital switching output suitable for magnetic sensing applications
• Regulatory Compliance: Both share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications
• Manufacturer Continuity: Both are produced by the same manufacturer, ensuring design consistency and support

Parameter Comparison

Engineering Selection Recommendations

The HAL1565 SU-A is the designated manufacturer substitute for the obsolete HAL566 SF-E. Selection of this alternative is supported by:

• Active Product Status: The HAL1565 SU-A maintains active production status, ensuring long-term availability and supply chain continuity
• Regulatory Alignment: Both components share identical export control and tariff classifications, maintaining compliance requirements
• Manufacturer Support: Direct substitution from TDK-Micronas GmbH eliminates compatibility uncertainty and provides access to current technical documentation
• Package Transition: Migration from SOT-89B to SOT-23-3 packaging requires PCB layout modification but represents a standard industry transition path for this component family

Frequently Asked Questions (FAQ)

Q: Why is the HAL566 SF-E no longer available? A: The HAL566 SF-E has reached obsolete product status. TDK-Micronas GmbH has transitioned this product line to the HAL1565 series, which offers improved performance characteristics and continued manufacturing support.

Q: What are the main differences between HAL566 SF-E and HAL1565 SU-A? A: The primary differences are package type (SOT-89B versus SOT-23-3), mounting configuration (surface mount for HAL1565 SU-A), and output type specification (open drain for HAL1565 SU-A). Both components function as digital magnetic switches within the HAL® sensor family.

Q: Can I use HAL1565 SU-A as a direct pin-for-pin replacement? A: No. The HAL1565 SU-A uses SOT-23-3 packaging while the HAL566 SF-E uses SOT-89B packaging. PCB layout and footprint modifications are required for implementation.

Q: Are there any compliance or regulatory concerns with this substitution? A: No. Both components share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The HAL1565 SU-A maintains ROHS3 compliance, supporting current regulatory requirements.

Q: What is the supply status of the HAL1565 SU-A? A: The HAL1565 SU-A is an active product with current manufacturing and distribution. Inventory availability is maintained through authorized distributors in Tape & Reel packaging format.
