Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4905LHALA1 is determined by the following critical parameters:

• Functional equivalence: Unipolar Hall Effect switch with open collector output
• Package compatibility: 3-SSIP SSO-3-02 through-hole mounting
• Polarization: South Pole detection
• Temperature range: Operating capability within -40°C to 150°C
• Supply voltage overlap: Minimum compatibility with 3.8V ~ 24V range
• Output current capability: Sufficient for 100mA maximum output current
• Regulatory compliance: ROHS3 and REACH compliance maintained

The TLE4906LHALA1 qualifies as a manufacturer-recommended substitute based on these criteria, despite variations in specific sensing thresholds and supply current specifications.

Parameter Comparison

Engineering Selection Recommendations

The TLE4906LHALA1 is the manufacturer-recommended substitute for the TLE4905LHALA1. Key selection considerations:

• The TLE4906LHALA1 maintains active product status, ensuring ongoing availability and supply chain stability compared to the Last Time Buy status of the TLE4905LHALA1.
• Both devices share identical package specifications (3-SSIP, SSO-3-02) and mounting type (through hole), enabling direct physical replacement without PCB redesign.
• Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.
• The TLE4906LHALA1 includes AEC-Q100 automotive qualification, providing additional reliability assurance for applications requiring automotive-grade components.
• The TLE4906LHALA1 operates within a narrower supply voltage range (2.7V ~ 18V) compared to the TLE4905LHALA1 (3.8V ~ 24V). Applications requiring operation above 18V supply voltage are not compatible with this substitute.
• The TLE4906LHALA1 has a lower maximum output current (20mA) compared to the TLE4905LHALA1 (100mA). Applications requiring output currents exceeding 20mA require circuit redesign or alternative components.
• The TLE4906LHALA1 has a lower trip threshold (13.5mT versus 18mT), resulting in increased sensitivity to magnetic field detection.

Frequently Asked Questions (FAQ)

Q: Can the TLE4906LHALA1 directly replace the TLE4905LHALA1 in all applications?

A: Direct replacement is possible only when application requirements fall within the TLE4906LHALA1 specifications. Verify that supply voltage does not exceed 18V and that output current requirements do not exceed 20mA. The lower trip threshold (13.5mT versus 18mT) may affect magnetic field detection sensitivity in specific applications.

Q: What is the significance of the Last Time Buy status for the TLE4905LHALA1?

A: Last Time Buy indicates that Infineon Technologies has discontinued production of this part. Existing inventory is limited, and no future manufacturing is planned. The TLE4906LHALA1 is recommended as the active alternative to ensure long-term supply availability.

Q: Are the package dimensions identical between these two parts?

A: Yes. Both the TLE4905LHALA1 and TLE4906LHALA1 use the 3-SSIP SSO-3-02 package with through-hole mounting. No PCB layout modifications are required for physical substitution.

Q: What is the difference in sensing range between these parts?

A: The TLE4905LHALA1 has a trip threshold of 18mT with 5mT release. The TLE4906LHALA1 has a trip threshold of 13.5mT with 5mT release. The TLE4906LHALA1 is more sensitive and will activate at lower magnetic field strengths.

Q: Does the TLE4906LHALA1 meet automotive standards?

A: Yes. The TLE4906LHALA1 carries AEC-Q100 automotive qualification, indicating compliance with automotive reliability and quality standards. The TLE4905LHALA1 does not specify automotive qualification.

Q: What are the regulatory compliance differences?

A: Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent between the two devices.
