TLE4275DNTMA1 Equivalent & Substitute Parts

Part Overview

The TLE4275DNTMA1 is a linear voltage regulator IC from Infineon Technologies designed for positive fixed 5V output at 450mA. This automotive-grade component features integrated protection against overcurrent, overtemperature, reverse polarity, short circuit, and transient voltage conditions. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across input voltage range, output current capacity, dropout voltage, and automotive qualification standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Output voltage matching at 5V fixed
• Output current capability of 450mA or greater
• Maximum input voltage of 42V or higher
• Dropout voltage not exceeding 0.5V @ 300mA
• Automotive grade classification with AEC-Q100 qualification
• Surface mount packaging in TO-252-5 (DPAK) form factor
• Operating temperature range of -40°C to 150°C

The substitute parts listed below satisfy these core electrical and mechanical requirements, enabling direct functional replacement in automotive applications.

Parameter Comparison

Engineering Selection Recommendations

TLE4275QKVURQ1 (Texas Instruments) provides the closest electrical match to the TLE4275DNTMA1, maintaining identical output current (450mA), dropout voltage (0.5V @ 300mA), and quiescent current (200 µA) specifications. This part is currently in active production status with AEC-Q100 automotive qualification, ensuring long-term availability and supply chain stability.

NCV4275CDT50RKG (onsemi) meets all core electrical requirements with equivalent 450mA output current and 0.5V dropout voltage. This part offers improved quiescent current performance (150 µA) and maintains full automotive grade certification with AEC-Q100 qualification and active product status.

NCV8675DT50RKG (onsemi) is suitable for applications where output current requirements can be reduced to 350mA. This part provides superior quiescent current performance (45 µA) and extended input voltage tolerance (45V maximum). Selection of this part requires confirmation that the 350mA output current is sufficient for the target application.

All substitute parts maintain automotive grade classification, AEC-Q100 qualification, and TO-252-5 package compatibility, ensuring compliance with automotive design standards and manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can TLE4275QKVURQ1 be used as a direct replacement for TLE4275DNTMA1?

A: Yes. TLE4275QKVURQ1 maintains identical electrical specifications for output voltage (5V), output current (450mA), dropout voltage (0.5V @ 300mA), and quiescent current (200 µA). Both parts are housed in TO-252-5 packaging and carry AEC-Q100 automotive qualification. The primary difference is product status: TLE4275QKVURQ1 is in active production.

Q: What is the key difference between NCV4275CDT50RKG and NCV8675DT50RKG?

A: The primary difference is output current capacity. NCV4275CDT50RKG provides 450mA output current matching the original part, while NCV8675DT50RKG is rated for 350mA. NCV8675DT50RKG offers lower quiescent current (45 µA versus 150 µA) and higher maximum input voltage (45V versus 42V). Selection depends on whether the application requires the full 450mA output current.

Q: Are all substitute parts compatible with automotive applications?

A: Yes. All listed substitute parts carry automotive grade classification and AEC-Q100 qualification, meeting automotive industry standards for reliability and quality.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts use identical TO-252-5 (DPAK) packaging with the same pinout and thermal characteristics, enabling direct PCB-level substitution without layout modifications.

Q: What should be considered when selecting between the three substitute options?

A: Selection should be based on output current requirements (450mA for TLE4275QKVURQ1 and NCV4275CDT50RKG; 350mA for NCV8675DT50RKG), quiescent current performance needs, and supply chain availability. All three parts meet the core electrical and automotive qualification requirements of the original TLE4275DNTMA1.
