HAL516 SF-K Equivalent & Substitute Parts

Part Overview

The HAL516 SF-K is a digital switch Hall effect magnetic sensor manufactured by TDK-Micronas GmbH, designed for surface mount applications in the SOT-89B-1 package. This component operates as an open drain output device with temperature compensation across a supply voltage range of 3.8V to 24V and an operating temperature range of -40°C to 140°C. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HAL516 SF-K is determined by the following critical parameters that must align between the original and substitute component:

• Technology: Hall effect magnetic sensing principle
• Output Configuration: Open drain output topology
• Supply Voltage Range: Compatibility within 3.8V to 24V operating window
• Output Current Capability: Minimum 20mA output current capacity
• Operating Temperature Range: Support for -40°C to 140°C junction temperature
• Mounting Type: Surface mount configuration
• Package Category: Small outline transistor packages suitable for equivalent footprint consideration

The HAL1509 SU-A qualifies as a manufacturer-recommended substitute based on these core electrical and mechanical parameters.

Engineering Selection Recommendations

The HAL1509 SU-A is the manufacturer-recommended substitute for the obsolete HAL516 SF-K. Selection of this substitute is supported by the following engineering factors:

• Product Status: The HAL1509 SU-A maintains active product status with TDK-Micronas GmbH, ensuring continued availability and manufacturing support compared to the obsolete HAL516 SF-K.
• Compliance: The HAL1509 SU-A is ROHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited), meeting modern regulatory requirements.
• Electrical Compatibility: Both components share Hall effect technology with open drain output configuration. The HAL1509 SU-A operates across an extended supply voltage range (2.7V ~ 24V) that encompasses the original specification (3.8V ~ 24V).
• Temperature Performance: The HAL1509 SU-A supports an extended operating temperature range (-40°C ~ 170°C) that exceeds the original component specification (-40°C ~ 140°C).
• Package Consideration: The HAL1509 SU-A uses SOT-23-3 packaging, which differs from the original SOT-89B-1 package. PCB layout modification is required for implementation.

Frequently Asked Questions (FAQ)

Q: Why is the HAL516 SF-K being discontinued? A: The HAL516 SF-K is classified as obsolete by the manufacturer. The HAL1509 SU-A represents the active product line continuation for this functional category.

Q: Are the output characteristics identical between HAL516 SF-K and HAL1509 SU-A? A: Both components feature open drain output topology with Hall effect technology. The HAL1509 SU-A is specified as a unipolar switch with defined sensing parameters (3.7mT trip, 5.5mT release), while the HAL516 SF-K specifications focus on general digital switch operation.

Q: What is the primary difference in packaging between these components? A: The HAL516 SF-K uses SOT-89B-1 (TO-243AA variant) packaging, while the HAL1509 SU-A uses SOT-23-3 (TO-236-3/SC-59) packaging. These are different form factors requiring PCB redesign for pin layout and footprint accommodation.

Q: Can the HAL1509 SU-A operate at the same supply voltages as the HAL516 SF-K? A: Yes. The HAL1509 SU-A supply voltage range (2.7V ~ 24V) fully encompasses the HAL516 SF-K specification (3.8V ~ 24V). The substitute component supports operation across the entire original voltage window and extends capability to lower supply voltages.

Q: What compliance certifications apply to the HAL1509 SU-A? A: The HAL1509 SU-A is ROHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating unrestricted shelf life and environmental compliance with current regulatory standards.

Q: Is the HAL1509 SU-A suitable for applications requiring the full -40°C to 140°C temperature range? A: Yes. The HAL1509 SU-A operating temperature range (-40°C ~ 170°C) exceeds the original specification, providing full compatibility and additional thermal margin for the original application requirements.
