HAL730SF-K Equivalent & Substitute Parts

Part Overview

The HAL730SF-K is a digital switch latch Hall Effect magnetic sensor manufactured by TDK-Micronas GmbH, designed for magnetic field detection applications requiring open drain output configuration. This component operates as a latching switch, responding to South Pole magnetic field polarization with trip and release thresholds of ±19.1mT. The product is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design requirements and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HAL730SF-K is determined by strict alignment of the following critical parameters:

• Function & Technology: Latching Hall Effect magnetic switch with open drain output
• Polarization: South Pole detection capability
• Sensing Threshold: Trip and release points within acceptable tolerance of ±19.1mT
• Voltage Supply Range: Compatibility with 3.8V ~ 24V operating envelope
• Output Current Capability: Minimum 20mA open drain output
• Operating Temperature Range: Coverage of -40°C ~ 140°C operational window
• Mounting & Package: Surface mount configuration with compatible pinout

The DRV5013BCQDBZR from Texas Instruments meets these substitution criteria through equivalent functional performance, Hall Effect technology, South Pole polarization, and open drain output architecture. While package form factors differ (SOT-23-3 versus SOT-89B-2), electrical compatibility and functional equivalence are maintained.

Engineering Selection Recommendations

The DRV5013BCQDBZR is the designated manufacturer-recommended substitute for the obsolete HAL730SF-K. Selection of this alternative is supported by the following engineering factors:

• Product Status: DRV5013BCQDBZR maintains active production status with established supply chain availability (15,775 Pcs in stock), whereas HAL730SF-K is obsolete with limited remaining inventory (2,400 Pcs).
• Compliance & Certification: DRV5013BCQDBZR is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.
• Functional Equivalence: Both components share identical Hall Effect technology, latching function, South Pole polarization, and open drain output configuration.
• Electrical Performance: DRV5013BCQDBZR demonstrates superior electrical characteristics including lower supply current consumption (2.7mA typical versus 9mA maximum), higher output current capability (30mA versus 20mA), and extended supply voltage range (2.7V ~ 38V versus 3.8V ~ 24V).
• Sensing Threshold Compatibility: Trip and release thresholds of 18.5mT / -18.5mT are within acceptable tolerance of the original 19.1mT / -19.1mT specification.

Package Consideration: The DRV5013BCQDBZR utilizes SOT-23-3 packaging versus the HAL730SF-K SOT-89B-2 package. PCB layout modification is required to accommodate the different form factor and pinout configuration.

Frequently Asked Questions (FAQ)

Q: Can the DRV5013BCQDBZR directly replace the HAL730SF-K without PCB modifications?

A: No. While electrically and functionally equivalent, the DRV5013BCQDBZR uses SOT-23-3 packaging compared to the HAL730SF-K SOT-89B-2 package. PCB footprint and layout modifications are necessary. Verify pinout compatibility and trace routing before implementation.

Q: What is the difference in sensing threshold between these components?

A: The HAL730SF-K operates at ±19.1mT, while the DRV5013BCQDBZR operates at ±18.5mT. This 0.6mT difference represents a 3.1% variance and is within acceptable tolerance for most magnetic switch applications. Verify application-specific threshold requirements before selection.

Q: Is the DRV5013BCQDBZR suitable for the full operating temperature range of the HAL730SF-K?

A: The DRV5013BCQDBZR operates from -40°C to 125°C, while the HAL730SF-K operates to 140°C. If your application requires operation above 125°C, the DRV5013BCQDBZR is not suitable. Verify maximum operating temperature requirements for your specific application.

Q: What are the supply current advantages of the DRV5013BCQDBZR?

A: The DRV5013BCQDBZR draws 2.7mA typical supply current compared to 9mA maximum for the HAL730SF-K. This 70% reduction in supply current consumption provides benefits for battery-powered and low-power applications.

Q: Are there any compliance or certification differences between these components?

A: The DRV5013BCQDBZR is RoHS3 compliant and REACH unaffected, meeting current regulatory standards. The HAL730SF-K, being obsolete, may not meet current compliance requirements. Verify regulatory requirements for your target market and application.

Q: What supply voltage range should I use for the DRV5013BCQDBZR?

A: The DRV5013BCQDBZR operates across 2.7V to 38V. If your design currently uses the HAL730SF-K within its 3.8V to 24V range, the DRV5013BCQDBZR will function within this envelope. The extended voltage range provides additional design flexibility.
