• Mounting Type: Through Hole compatibility
• Operating Temperature Range: -40°C ~ 150°C (TJ)
• Automotive Grade: AEC-Q100 qualification
• RoHS Compliance: ROHS3 Compliant status

The TLE4905LHALA1 meets all substitution criteria as a functionally equivalent alternative, maintaining identical package geometry, output architecture, temperature operating range, and automotive qualification standards.

Parameter Comparison

Engineering Selection Recommendations

The TLE4905LHALA1 serves as the primary substitute for the obsolete TLE4976LHALA1. Both components maintain identical package geometry, mounting configuration, and automotive qualification standards. The TLE4905LHALA1 retains Last Time Buy status, providing extended procurement availability compared to the Obsolete classification of the original part.

Key considerations for component selection:

• Both parts maintain AEC-Q100 automotive qualification and ROHS3 compliance
• Identical package and mounting specifications ensure direct physical compatibility
• Operating temperature range remains consistent across both components
• Supply voltage range of TLE4905LHALA1 extends to 24V maximum, accommodating broader system requirements
• Sensing range differential (18mT Trip vs. 11mT Trip) requires application-level validation for magnetic field sensitivity requirements

Frequently Asked Questions (FAQ)

Q: Can the TLE4905LHALA1 directly replace the TLE4976LHALA1 in existing designs?

A: Physical and electrical compatibility is established through identical package specifications (3-SSIP, SSO-3-02), matching output type (Open Collector), and equivalent operating temperature range (-40°C ~ 150°C). Application-specific validation is required for magnetic sensing threshold differences.

Q: What is the primary difference between these two components?

A: The sensing range trip point differs: TLE4976LHALA1 operates at 11mT, while TLE4905LHALA1 operates at 18mT. This parameter determines the magnetic field strength required to activate the switch output.

Q: Are both components automotive-qualified?

A: Both the TLE4976LHALA1 and TLE4905LHALA1 carry AEC-Q100 qualification and are ROHS3 compliant, meeting automotive-grade standards.

Q: What is the packaging format for these components?

A: Both components utilize the 3-SSIP, SSO-3-02 package with through-hole mounting configuration.

Q: Why is the TLE4976LHALA1 classified as Obsolete?

A: Obsolete status indicates the component is no longer in active production. The TLE4905LHALA1, classified as Last Time Buy, represents the recommended alternative for new designs and ongoing procurement requirements.
