Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS466A-T3 is determined by strict alignment of the following critical parameters:

Functional Parameters: Function (Latch), Technology (Hall Effect), and Polarization (South Pole) must match exactly.

Electrical Parameters: Sensing range (18mT Trip, -18mT Release) and output type (Open Collector/Open Drain) must be compatible. Supply voltage range and output current ratings must support the application requirements.

Physical Parameters: Package type (TO-92-3 Short Body) and mounting method (Through Hole) must be identical to ensure mechanical compatibility with existing PCB layouts.

Environmental Parameters: Operating temperature range must encompass or match the application's thermal requirements.

The DRV5013BCQLPG from Texas Instruments qualifies as a substitute based on matching function, technology, polarization, sensing range, package type, and mounting method. Differences in supply voltage range, output current capability, and operating temperature ceiling are noted in the parameter comparison.

Engineering Selection Recommendations

The DRV5013BCQLPG is a direct functional substitute for the obsolete SS466A-T3 magnetic latch switch. Both components share identical sensing characteristics, output behavior, and physical form factor, enabling pin-compatible replacement in through-hole applications.

Compliance Status: The DRV5013BCQLPG maintains active production status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The SS466A-T3, being obsolete, presents supply chain risk for new designs and ongoing production.

Electrical Considerations: The DRV5013BCQLPG operates across a wider supply voltage range (2.7V ~ 38V versus 3.8V ~ 30V), providing greater design flexibility. Output current capability is increased to 30mA, supporting higher load requirements. Supply current consumption is reduced to 2.7mA typical, improving power efficiency.

Thermal Considerations: The SS466A-T3 specifies operation to 150°C, while the DRV5013BCQLPG is rated to 125°C. Applications requiring operation above 125°C must retain the original component or identify alternative solutions. For standard industrial and commercial temperature ranges, the DRV5013BCQLPG is suitable.

Certification: Both components carry EAR99 export classification and identical HTSUS codes, with no additional regulatory barriers to substitution.

Frequently Asked Questions (FAQ)

Q: Can the DRV5013BCQLPG directly replace the SS466A-T3 in existing designs?

A: Yes, for applications operating within -40°C to 125°C. The DRV5013BCQLPG is pin-compatible, functionally equivalent, and shares identical sensing range and output characteristics. Applications requiring operation above 125°C require alternative solutions.

Q: What is the difference between Open Collector and Open Drain outputs?

A: Both output types function identically in circuit operation, requiring external pull-up resistors to establish logic levels. The terminology differs by manufacturer convention; the functional behavior is equivalent for this application.

Q: Does the wider supply voltage range of the DRV5013BCQLPG affect circuit design?

A: No. The DRV5013BCQLPG operates across 2.7V to 38V, encompassing the SS466A-T3 range of 3.8V to 30V. Existing power supply designs require no modification.

Q: Are there package differences between these components?

A: Both use TO-92-3 Short Body through-hole packages. Physical dimensions and pin spacing are identical, enabling direct PCB layout compatibility.

Q: What is the significance of the DRV5013BCQLPG being in active production?

A: Active production status ensures component availability, consistent manufacturing quality, and long-term supply chain stability. The obsolete SS466A-T3 presents increasing sourcing difficulty and potential quality variation from remaining inventory.

Q: How do the current consumption specifications compare?

A: The SS466A-T3 draws 10mA maximum supply current, while the DRV5013BCQLPG draws 2.7mA typical. The DRV5013BCQLPG offers improved power efficiency, beneficial for battery-powered or low-power applications.

Q: Is the DRV5013BCQLPG suitable for high-temperature applications?

A: The DRV5013BCQLPG operates to 125°C maximum. Applications requiring sustained operation above 125°C must use the original SS466A-T3 or identify alternative components rated for higher temperatures.
