TLE4935G Equivalent & Substitute Parts

Part Overview

The TLE4935G is a digital switch latch Hall Effect magnetic sensor manufactured by Infineon Technologies, designed for applications requiring magnetic field detection with open collector output. The device operates across a wide supply voltage range (4V to 18V) and features temperature compensation for stable performance across industrial temperature ranges (-40°C to 125°C).

The TLE4935G is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support long-term product availability for applications currently utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4935G is determined by the following critical parameters:

Core Functional Requirements:

• Hall Effect technology with latch function
• South pole polarization
• Open collector output configuration
• Surface mount packaging in TO-243AA or compatible variant

Electrical Compatibility Criteria:

• Supply voltage range must encompass or overlap with 4V ~ 18V
• Output current capability must meet or exceed 100mA
• Sensing threshold (trip/release points) must be compatible with application requirements
• Operating temperature range must cover -40°C ~ 125°C

Physical Compatibility:

• Package type: TO-243AA or approved variant
• Mounting type: Surface mount

The VF526DT from Honeywell Sensing and Productivity Solutions meets these substitution criteria as an active product with compatible Hall Effect latch functionality, open collector output, and surface mount packaging.

Engineering Selection Recommendations

Product Status Consideration: The VF526DT is classified as active product status, ensuring ongoing manufacturer support, availability, and supply chain continuity. This addresses the primary limitation of the obsolete TLE4935G.

Compliance and Certifications: The VF526DT carries RoHS Compliant certification, meeting modern environmental and regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, maintaining regulatory consistency.

Electrical Performance Trade-offs: The VF526DT provides expanded supply voltage range (3.5V ~ 24V versus 4V ~ 18V), offering greater design flexibility. However, the output current maximum is reduced to 10mA compared to the TLE4935G's 100mA. Applications requiring the full 100mA output capability must evaluate this limitation against functional requirements.

The release threshold differs (VF526DT: -6mT versus TLE4935G: -20mT), which may affect hysteresis characteristics in specific magnetic field applications.

Packaging Compatibility: Both devices use TO-243AA packaging with surface mount configuration, ensuring mechanical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the VF526DT directly replace the TLE4935G in all applications?

A: The VF526DT is functionally compatible as a Hall Effect latch sensor with open collector output and matching polarization. However, two parameters require evaluation: output current capability (10mA maximum versus 100mA) and release threshold (-6mT versus -20mT). Applications must confirm these specifications align with circuit requirements before implementation.

Q: What is the significance of the "Dual" function designation for the VF526DT?

A: The VF526DT incorporates dual output capability, providing two independent open collector outputs. Applications utilizing single output may use one output channel, while designs requiring dual outputs benefit from integrated functionality.

Q: Are the packages physically interchangeable?

A: Both devices use TO-243AA surface mount packaging. The VF526DT is specified as TO-243AA Variant, indicating minor dimensional or pin configuration differences. PCB layout verification is required to confirm mechanical fit and pin alignment before production implementation.

Q: What is the impact of the different supply voltage ranges?

A: The VF526DT's expanded range (3.5V ~ 24V) accommodates broader power supply designs compared to the TLE4935G (4V ~ 18V). The lower minimum voltage (3.5V) enables operation in lower-voltage systems, while the higher maximum (24V) supports industrial 24V supply rails.

Q: How do the sensing thresholds compare?

A: Both devices trigger at 20mT. The release threshold differs: TLE4935G releases at -20mT while VF526DT releases at -6mT. This affects the hysteresis window and magnetic field behavior. Application-specific magnetic field profiles must be evaluated to ensure the VF526DT's narrower hysteresis meets functional requirements.

Q: Is the VF526DT RoHS compliant?

A: Yes, the VF526DT is RoHS Compliant. The TLE4935G's RoHS status is not specified in available documentation. For applications requiring RoHS compliance, the VF526DT provides documented certification.
