Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4966H is determined by strict equivalence across the following critical parameters:

• Functional Equivalence: Bipolar Hall Effect switch with open collector output
• Electrical Specifications: Supply voltage range 2.7V ~ 18V, maximum supply current 7mA, maximum output current 10mA
• Sensing Characteristics: Magnetic polarization (North Pole, South Pole), sensing range 10mT trip and -10mT release at 25°C test condition
• Thermal Performance: Operating temperature range -40°C ~ 150°C with temperature compensation
• Mechanical Compatibility: Surface mount technology, SOT-23-6 Thin package (TSOT-23-6), PG-TSOP6-6 supplier device package

The substitute part TLE4966KHTSA1 maintains full electrical and mechanical compatibility with the TLE4966H across all specified parameters, with the addition of automotive-grade qualification (AEC-Q100) and RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The TLE4966KHTSA1 serves as the direct substitute for the obsolete TLE4966H. Both components are manufactured by Infineon Technologies and share identical electrical and mechanical specifications across all critical parameters including supply voltage, sensing range, output characteristics, and operating temperature range.

The TLE4966KHTSA1 carries automotive-grade qualification (AEC-Q100) and RoHS3 compliance, making it suitable for applications requiring enhanced reliability standards. The component is classified as "Not For New Designs," indicating limited availability for future production; however, it remains the specified equivalent for direct replacement of TLE4966H in existing designs.

Selection between these parts should be based on application requirements: the TLE4966KHTSA1 is preferred for automotive and high-reliability applications due to its AEC-Q100 qualification, while both parts are electrically and mechanically interchangeable for standard industrial applications.

Frequently Asked Questions (FAQ)
