TLE4476DATMA2 Equivalent & Substitute Parts

Part Overview

The TLE4476DATMA2 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for positive fixed dual-output regulation at 3.3V and 5V. This Surface Mount device in TO-252-5 packaging delivers 350mA and 430mA output currents respectively, with integrated protection features including over-current, over-temperature, over-voltage, reverse polarity, and short-circuit protection. The part is qualified to AEC-Q100 automotive standards and operates across -40°C to 170°C.

The TLE4476DATMA2 is currently listed as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4476DATMA2 is determined by strict equivalence across the following critical parameters:

• Dual positive fixed-output voltage regulation at 3.3V and 5V
• Output current capability of 350mA and 430mA respectively
• Maximum input voltage of 42V
• Dropout voltage specification of 0.7V @ 330mA
• TO-252-5 package configuration with identical pinout
• Automotive grade qualification and AEC-Q100 certification
• Identical protection feature set: over-current, over-temperature, over-voltage, reverse polarity, and short-circuit protection
• Operating temperature range of -40°C to 170°C
• Quiescent current of 150 µA

The TLE4476DATMA1 meets all these criteria and is classified as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The TLE4476DATMA1 is the direct equivalent substitute for the obsolete TLE4476DATMA2. Both parts share identical electrical specifications, package configuration, and automotive qualification status. The primary distinction is product lifecycle status: the TLE4476DATMA2 is obsolete, while the TLE4476DATMA1 maintains active production status.

For new designs or ongoing production requiring this dual-output linear regulator topology, the TLE4476DATMA1 is the appropriate selection. Both parts carry AEC-Q100 automotive qualification and ROHS3 compliance (TLE4476DATMA1), ensuring suitability for automotive and industrial applications requiring regulated 3.3V and 5V outputs with integrated protection mechanisms.

Frequently Asked Questions (FAQ)

Q: Can the TLE4476DATMA1 be used as a direct replacement for the TLE4476DATMA2?

A: Yes. The TLE4476DATMA1 is electrically and mechanically identical to the TLE4476DATMA2. Both devices provide dual positive fixed-output regulation at 3.3V and 5V with 350mA and 430mA output currents, identical dropout voltage, quiescent current, protection features, and TO-252-5 package configuration. The TLE4476DATMA1 is currently in active production.

Q: What is the significance of the product status difference between these parts?

A: The TLE4476DATMA2 is classified as obsolete, indicating Infineon has discontinued production. The TLE4476DATMA1 maintains active status, meaning it is currently manufactured and available through authorized distributors. For supply chain continuity, the TLE4476DATMA1 is the recommended selection.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are qualified to AEC-Q100 automotive standards and operate across -40°C to 170°C. The TLE4476DATMA1 carries explicit ROHS3 compliance certification. Both parts are REACH Unaffected. These certifications ensure suitability for automotive and industrial applications.

Q: Is the TO-252-5 package pinout identical between these parts?

A: Yes. Both the TLE4476DATMA2 and TLE4476DATMA1 use the TO-252-5 package configuration (DPAK with 4 Leads + Tab, TO-252AD designation). Pinout and PCB footprint are identical, enabling direct board-level substitution without layout modifications.

Q: What protection features are included in both parts?

A: Both the TLE4476DATMA2 and TLE4476DATMA1 incorporate over-current, over-temperature, over-voltage, reverse polarity, and short-circuit protection. These integrated protection mechanisms ensure robust operation in automotive and industrial environments.
