Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE4906H are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Hall Effect technology implementation
• Unipolar switch function with open collector/drain output
• Surface mount packaging (SC-59 / SOT-23-3)
• Operating voltage range overlap
• Magnetic sensing polarity and trip/release thresholds
• Output current capability
• Operating temperature range

Substitute Classification:

Direct Substitute (Active Status): TLE4906KHTSA1 maintains identical electrical specifications, sensing characteristics, and package configuration as the TLE4906H. This part is manufactured by Infineon Technologies and carries active product status with automotive-grade qualification (AEC-Q100).

Alternative Substitute (Obsolete Status): AH183-WG-7 is manufactured by Diodes Incorporated and shares the same package footprint and Hall Effect technology. However, this part exhibits different electrical parameters including reduced supply voltage range (2.5V ~ 5.5V), lower supply current (500µA), reduced output current (10mA), and different magnetic sensing characteristics (North Pole polarity, -6mT Trip, 1mT Release). Operating temperature range is also reduced to -40°C ~ 85°C.

Engineering Selection Recommendations

Recommended Primary Substitute: TLE4906KHTSA1

The TLE4906KHTSA1 is the preferred substitute for the obsolete TLE4906H. This part is manufactured by the same supplier (Infineon Technologies) and maintains complete electrical and functional equivalence. The TLE4906KHTSA1 carries active product status, ensuring long-term availability and supply chain stability. The part holds AEC-Q100 automotive qualification and is ROHS3 compliant, meeting modern regulatory requirements. Packaging and pinout are identical, enabling direct board-level substitution without design modification.

Alternative Substitute: AH183-WG-7

The AH183-WG-7 manufactured by Diodes Incorporated shares the same physical package and Hall Effect sensing technology. However, this part is also classified as obsolete and exhibits significant electrical parameter differences. The reduced supply voltage range (2.5V ~ 5.5V versus 2.7V ~ 18V), lower output current capability (10mA versus 20mA), different magnetic polarity (North Pole versus South Pole), and reduced operating temperature range (-40°C ~ 85°C versus -40°C ~ 150°C) make this substitute suitable only for applications where these parameter constraints are acceptable. The AH183-WG-7 is not recommended as a primary choice due to its obsolete status and parameter limitations.

Frequently Asked Questions (FAQ)

Q: Can TLE4906KHTSA1 be used as a direct replacement for TLE4906H?

A: Yes. The TLE4906KHTSA1 is electrically and functionally equivalent to the TLE4906H. Both parts share identical supply voltage range (2.7V ~ 18V), sensing characteristics (13.5mT Trip, 5mT Release), output current capability (20mA), operating temperature range (-40°C ~ 150°C), and package configuration (SC-59). No circuit modifications are required for substitution.

Q: What are the key differences between TLE4906KHTSA1 and AH183-WG-7?

A: The primary differences are: (1) Magnetic polarity—TLE4906KHTSA1 responds to South Pole while AH183-WG-7 responds to North Pole; (2) Supply voltage range—TLE4906KHTSA1 operates from 2.7V to 18V while AH183-WG-7 operates from 2.5V to 5.5V; (3) Output current—TLE4906KHTSA1 supports 20mA maximum while AH183-WG-7 supports 10mA; (4) Operating temperature—TLE4906KHTSA1 operates to 150°C while AH183-WG-7 operates to 85°C; (5) Product status—TLE4906KHTSA1 is active while AH183-WG-7 is obsolete.

Q: Is the AH183-WG-7 suitable for high-temperature applications?

A: No. The AH183-WG-7 has a maximum operating temperature of 85°C, which is significantly lower than the TLE4906H specification of 150°C. Applications requiring operation above 85°C must use TLE4906KHTSA1.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the SC-59 package (TO-236-3, SOT-23-3), which provides identical pinout and footprint compatibility. However, electrical parameter differences must be verified for circuit compatibility before substitution.

Q: What is the supply current difference between TLE4906KHTSA1 and AH183-WG-7?

A: The TLE4906KHTSA1 has a maximum supply current of 6mA, while the AH183-WG-7 has a maximum supply current of 500µA. The AH183-WG-7 draws significantly less current, which may be advantageous in power-constrained applications but does not affect functional compatibility if other parameters are acceptable.

Q: Why is TLE4906KHTSA1 preferred over AH183-WG-7?

A: TLE4906KHTSA1 is preferred because it maintains complete parameter equivalence with the original TLE4906H, carries active product status ensuring availability, holds AEC-Q100 automotive qualification, and is ROHS3 compliant. The AH183-WG-7, while sharing the same package, introduces parameter constraints that limit its applicability and is also obsolete.
