TLE4275GV33ATMA1 Equivalent & Substitute Parts

Part Overview

The TLE4275GV33ATMA1 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed to deliver a fixed 3.3V output at 400mA. This device is classified as Obsolete, which necessitates identification of active alternative components for new designs and production continuity. The part features automotive-grade qualification (AEC-Q100) and comprehensive protection mechanisms including over-current, over-temperature, reverse polarity, short-circuit, and transient voltage protection. Finding equivalent substitutes ensures design flexibility and supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4275GV33ATMA1 is determined by the following critical parameters:

• Fixed output voltage of 3.3V
• Output current capability of 400mA or greater
• Maximum input voltage of 40V or higher
• Automotive-grade qualification (AEC-Q100)
• Operating temperature range of -40°C to 150°C
• Surface-mount packaging compatible with TO-263 or TO-252 footprints
• ROHS3 compliance and automotive-grade protection features

The identified substitutes maintain these core electrical and mechanical specifications while offering improved product status (Active) and enhanced performance characteristics such as lower quiescent current and better dropout voltage performance.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are classified as Active products with full AEC-Q100 automotive qualification, providing superior supply chain availability compared to the Obsolete TLE4275GV33ATMA1.

The TLS850C2TEV33ATMA1 (Infineon Technologies) offers the highest output current capability at 500mA with significantly reduced quiescent current of 30 µA, making it suitable for applications requiring extended battery life or lower standby power consumption. This part uses TO-252-5 (DPAK) packaging, which differs from the original TO-263-6 (D2PAK) footprint and requires PCB layout modification.

The NCV4275CDS33R4G (onsemi) maintains the original TO-263-6 (D2PAK) package footprint, enabling direct PCB compatibility without layout redesign. It provides 450mA output current with improved dropout voltage performance (0.5V @ 300mA) and moderate quiescent current of 150 µA. This part is recommended for designs prioritizing minimal PCB rework.

Both substitutes maintain the full automotive-grade protection feature set and ROHS3 compliance required for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can TLS850C2TEV33ATMA1 be used as a direct replacement without PCB modification?

A: No. The TLS850C2TEV33ATMA1 uses TO-252-5 (DPAK) packaging, while the original TLE4275GV33ATMA1 uses TO-263-6 (D2PAK) packaging. These packages have different pin configurations and footprints, requiring PCB layout changes.

Q: Can NCV4275CDS33R4G be used as a direct replacement without PCB modification?

A: Yes. The NCV4275CDS33R4G uses the same TO-263-6 (D2PAK) package as the original part, maintaining identical pin configuration and PCB footprint compatibility.

Q: What is the minimum output current requirement for substitution?

A: The substitute part must deliver at least 400mA to meet the original specification. Both identified substitutes exceed this requirement at 500mA and 450mA respectively.

Q: Are both substitutes qualified for automotive applications?

A: Yes. Both TLS850C2TEV33ATMA1 and NCV4275CDS33R4G hold AEC-Q100 automotive qualification and are classified as Automotive-grade components.

Q: What is the maximum input voltage tolerance for substitution?

A: The original part specifies 42V maximum input voltage. The TLS850C2TEV33ATMA1 has a 40V maximum rating, which is 2V lower. The NCV4275CDS33R4G maintains the 42V maximum rating. Applications operating near 40V should use the NCV4275CDS33R4G.

Q: Do both substitutes provide the same protection features?

A: The TLS850C2TEV33ATMA1 provides over-current, over-temperature protection. The NCV4275CDS33R4G provides over-temperature, reverse-polarity, and short-circuit protection. The original part includes all five protection mechanisms. Application-specific requirements should determine which substitute is appropriate.
