TLE7272D Equivalent & Substitute Parts

Part Overview

The TLE7272D is a linear voltage regulator IC manufactured by Infineon Technologies, designed to provide a fixed 5V output at 300mA. This Surface Mount device in TO-252-5 packaging is classified as Obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

The obsolete status of the TLE7272D necessitates sourcing equivalent components that maintain electrical and mechanical compatibility while offering active product availability and modern manufacturing support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE7272D is determined by the following critical parameters:

• Output Voltage: Must be fixed at 5V
• Package / Case: Must be TO-252-5 (DPAK with 4 Leads + Tab)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -40°C ~ 150°C
• Output Current: Must meet or exceed 300mA requirement
• Input Voltage (Max): Must support minimum 42V input
• Protection Features: Must include Over Current and Over Temperature protection

Both identified substitute parts meet these core substitution criteria while offering active product status and improved availability compared to the obsolete TLE7272D.

Parameter Comparison

Engineering Selection Recommendations

TPS7A6050QKVURQ1 is the primary substitute for direct replacement of the TLE7272D. This part maintains identical output current specification (300mA), matching the original design requirements precisely. Both devices share equivalent dropout voltage performance and operating temperature range. The TPS7A6050QKVURQ1 carries Active product status with AEC-Q100 automotive qualification and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

TLE4275QKVURQ1 serves as an alternative substitute with enhanced output current capability (450mA). This part accommodates designs requiring higher current headroom while maintaining all core electrical parameters. The TLE4275QKVURQ1 also carries Active status with AEC-Q100 qualification and ROHS3 compliance. Selection of this part is appropriate when system design permits utilization of the increased current capacity.

Both substitutes are pin-compatible in TO-252-5 packaging and support the full operating temperature range of the original device.

Frequently Asked Questions (FAQ)

Q: Can TPS7A6050QKVURQ1 directly replace TLE7272D without PCB modification?

A: Yes. Both parts use identical TO-252-5 packaging with matching pinout. No PCB layout changes are required for direct substitution.

Q: What is the difference between TPS7A6050QKVURQ1 and TLE4275QKVURQ1?

A: The primary difference is output current rating. TPS7A6050QKVURQ1 provides 300mA (matching the original TLE7272D), while TLE4275QKVURQ1 provides 450mA. Both maintain 5V fixed output and identical package configuration. Selection depends on system current requirements.

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both TPS7A6050QKVURQ1 and TLE4275QKVURQ1 carry AEC-Q100 automotive qualification, making them suitable for automotive-grade designs.

Q: What is the input voltage limitation for TPS7A6050QKVURQ1?

A: Maximum input voltage is 40V, compared to 42V for the original TLE7272D. Verify that your system input voltage does not exceed 40V when selecting this substitute.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both TPS7A6050QKVURQ1 and TLE4275QKVURQ1 are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the quiescent current difference between the substitutes?

A: TPS7A6050QKVURQ1 has 40 µA quiescent current, while TLE4275QKVURQ1 has 200 µA. For low-power standby applications, TPS7A6050QKVURQ1 is the preferred choice.
