HAL730SF-E Equivalent & Substitute Parts

Part Overview

The HAL730SF-E 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 eligibility for the HAL730SF-E is determined by the following critical parameters:

• Function: Latching Hall Effect switch operation
• Output Configuration: Open drain topology
• Polarization: South Pole magnetic field detection
• Sensing Threshold: Magnetic field trip and release points within acceptable tolerance
• Voltage Supply Compatibility: Operating range must encompass or exceed the original 3.8V – 24V specification
• Output Current Capability: Minimum 20mA to support existing load requirements
• Temperature Range: Operating temperature envelope must support -40°C to 100°C minimum
• Mounting: Surface mount package suitable for PCB integration
• Compliance: RoHS and REACH compliance for current manufacturing standards

The DRV5013BCQDBZR from Texas Instruments qualifies as a direct functional equivalent based on matching latch function, open drain output, South Pole polarization, and Hall Effect technology. While package geometry differs (SOT-23-3 versus SOT-89B-2), electrical performance parameters align within acceptable substitution criteria.

Engineering Selection Recommendations

The DRV5013BCQDBZR is suitable as a functional replacement for the obsolete HAL730SF-E based on the following criteria:

Electrical Compatibility: The substitute maintains core electrical specifications including latch function, open drain output, South Pole polarization, and Hall Effect sensing technology. Sensing threshold variance (18.5mT versus 19.1mT) represents a 3.1% difference within typical sensor tolerance bands. Supply voltage range expansion (2.7V – 38V) and increased output current capability (30mA) provide enhanced operational flexibility without compromising existing circuit requirements.

Thermal Performance: Extended operating temperature range (-40°C to 125°C) exceeds the original specification, supporting broader environmental deployment scenarios.

Compliance Status: The DRV5013BCQDBZR carries active product status with ROHS3 compliance and REACH unaffected designation, meeting current manufacturing and environmental regulatory requirements. The HAL730SF-E obsolete status necessitates transition to actively supported alternatives.

Package Consideration: Substitution requires PCB layout modification due to package geometry change from SOT-89B-2 to SOT-23-3. Pin configuration and footprint redesign are mandatory for implementation.

Frequently Asked Questions (FAQ)

Q: Can the DRV5013BCQDBZR directly replace the HAL730SF-E without PCB modification?

A: No. While electrical specifications are compatible, the package geometry differs fundamentally. SOT-89B-2 and SOT-23-3 packages have different pin spacing, lead configurations, and footprints. PCB layout redesign and component footprint modification are required.

Q: What is the significance of the 0.6mT sensing threshold difference?

A: The HAL730SF-E operates at 19.1mT trip threshold while the DRV5013BCQDBZR operates at 18.5mT. This 0.6mT variance represents approximately 3.1% difference and falls within standard Hall Effect sensor tolerance specifications. Applications with tight magnetic field margin requirements should evaluate this difference against specific design thresholds.

Q: Is the DRV5013BCQDBZR suitable for the full -40°C to 100°C temperature range of the original design?

A: Yes. The DRV5013BCQDBZR operates across -40°C to 125°C, which encompasses and exceeds the original -40°C to 100°C requirement. No thermal performance degradation occurs within the original operating envelope.

Q: What are the supply current implications of substitution?

A: The DRV5013BCQDBZR draws 2.7mA typical supply current compared to the HAL730SF-E maximum of 9mA. This represents reduced power consumption, which may benefit battery-powered or low-power applications. Circuit design should not assume the higher current draw of the original component.

Q: Are there compliance or regulatory differences between these components?

A: The DRV5013BCQDBZR carries ROHS3 compliance and REACH unaffected status, meeting current environmental and manufacturing standards. The HAL730SF-E obsolete status indicates it no longer receives manufacturer support or compliance updates. New designs should prioritize the actively supported substitute.

Q: What output current capability is available with the DRV5013BCQDBZR?

A: Maximum output current is 30mA, exceeding the HAL730SF-E specification of 20mA. Existing load circuits designed for 20mA operation remain fully compatible.
