Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4935LHALA1 is determined by the following critical parameters:

Functional Compatibility: All substitute parts must operate as digital switch latch Hall Effect sensors with open collector output and south pole polarization.

Electrical Compatibility: Supply voltage range, maximum supply current, and maximum output current must support the application requirements. The TLE4935LHALA1 operates at 3.8V ~ 24V with 100mA maximum output current.

Sensing Characteristics: Magnetic trip and release thresholds determine sensor sensitivity. The TLE4935LHALA1 operates at 20mT trip and -20mT release points.

Thermal Performance: Operating temperature range and temperature compensation features must meet application requirements. The TLE4935LHALA1 operates from -40°C to 150°C (TJ).

Compliance & Certification: Automotive-grade classification and AEC-Q100 qualification are mandatory for equivalent substitution in automotive applications.

Mounting & Packaging: Through hole mounting with 3-SSIP/SSO-3-02 package defines the physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes with Through Hole Mounting:

The AH1751-PG-A-A and AH1751-PG-B-A from Diodes Incorporated provide the closest functional equivalence to the TLE4935LHALA1. Both parts maintain 100mA maximum output current, matching the original specification. These components operate across 3.5V ~ 20V supply voltage, which overlaps the TLE4935LHALA1 range. The 7mT sensing threshold differs from the original 20mT specification but remains within the same product family logic. Both parts carry automotive grade classification and AEC-Q100 qualification, ensuring compliance with automotive requirements. Operating temperature range extends to -40°C ~ 125°C (TA), which is slightly lower than the original -40°C ~ 150°C (TJ) specification.

Alternative Substitutes with Reduced Output Current:

The AH175-PG-A-A, AH175-PG-A-B, AH175-PG-B-A, and AH175-PG-B-B from Diodes Incorporated are functionally compatible but feature reduced maximum output current of 25mA compared to the original 100mA. These parts are suitable for applications where output current requirements do not exceed 25mA. Sensing thresholds vary between 6mT and 8mT. All parts maintain automotive grade and AEC-Q100 qualification.

Surface Mount Alternative:

The TLE49462KHTSA1 from Infineon Technologies is a surface mount variant with SC-59 package. This part operates at 3.5mT sensing threshold with reduced maximum output current of 20mA. Supply voltage range is 2.7V ~ 18V. This option is applicable only for designs that can accommodate surface mount technology and do not require the original 100mA output current capability.

Frequently Asked Questions (FAQ)

Q: Can the AH1751-PG-A-A directly replace the TLE4935LHALA1 in my circuit?

A: The AH1751-PG-A-A is functionally compatible as a through hole mounted Hall Effect latch sensor with 100mA output current capability. However, the sensing threshold differs at 7mT compared to the original 20mT. Verify that your application can operate with this different magnetic sensitivity level. Both parts carry AEC-Q100 qualification and automotive grade classification.

Q: What is the key difference between the AH175 and AH1751 series?

A: The primary difference is maximum output current. The AH1751 series supports 100mA output current, matching the TLE4935LHALA1 specification. The AH175 series is limited to 25mA output current. Select based on your circuit's output current requirements.

Q: Why does the TLE49462KHTSA1 have a different package type?

A: The TLE49462KHTSA1 uses surface mount SC-59 packaging instead of through hole 3-SSIP. This requires different PCB layout and assembly processes. Use this part only if your design supports surface mount technology.

Q: Are all substitute parts RoHS3 compliant and AEC-Q100 qualified?

A: All substitute parts listed are ROHS3 compliant and carry AEC-Q100 automotive qualification, ensuring compliance with automotive industry standards and environmental regulations.

Q: What happens if I use a substitute with a different sensing threshold?

A: The magnetic trip and release thresholds determine when the sensor activates. Using a part with different thresholds (for example, 7mT instead of 20mT) changes the magnetic field strength required to trigger the sensor. Ensure your application's magnetic field environment is compatible with the substitute part's sensitivity specification.

Q: Can I use the AH175 series parts if my application requires 100mA output current?

A: No. The AH175 series is limited to 25mA maximum output current. For applications requiring 100mA output capability, use the AH1751 series or the original TLE4935LHALA1.

Q: What is the temperature difference between TJ and TA specifications?

A: TJ refers to junction temperature, while TA refers to ambient temperature. The TLE4935LHALA1 specifies -40°C ~ 150°C (TJ), while substitute parts from Diodes Incorporated specify -40°C ~ 125°C (TA). Verify that your application's thermal environment is compatible with the specified temperature range.
