Substitute Part Grouping Explanation

Substitution for the TLE4266-2GS V33 is determined by strict alignment of the following electrical and mechanical parameters:

• Output voltage: 3.3V fixed
• Output current capability: 150mA minimum
• Package type: SOT-223-4 (TO-261-4, TO-261AA)
• Operating temperature range: -40°C to 150°C
• Automotive grade with AEC-Q100 qualification
• Protection features: Over-temperature and short-circuit protection

The substitute parts identified maintain these core specifications, ensuring functional and mechanical compatibility within the same application context.

Parameter Comparison

Engineering Selection Recommendations

TLE42662GSV33HTMA2 (Infineon Technologies) is the parametric equivalent substitute. This part maintains identical electrical specifications to the original TLE4266-2GS V33, including output voltage, current rating, dropout voltage, and quiescent current. Both components share the same OPTIREG™ series lineage and automotive qualification. The primary distinction is product status: TLE42662GSV33HTMA2 is active and available in Tape & Reel packaging, whereas the original is obsolete. This substitute provides direct functional replacement with no design modifications required.

TPS7B6933QDCYRQ1 (Texas Instruments) is the manufacturer-recommended alternative from a different supplier. While maintaining the same output voltage, current capability, package type, and automotive qualification, this part exhibits improved performance characteristics: lower dropout voltage (0.8V vs. 1.1V) and reduced quiescent current (25 µA vs. 60 µA). The maximum input voltage is reduced to 40V. This substitute is suitable for applications where the lower input voltage specification is acceptable and where improved efficiency is beneficial.

Both substitutes are active products with AEC-Q100 qualification and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can TLE42662GSV33HTMA2 be used as a direct replacement for TLE4266-2GS V33?

A: Yes. TLE42662GSV33HTMA2 is a parametric equivalent with identical electrical specifications, including output voltage (3.3V), output current (150mA), dropout voltage (1.1V @ 100mA), and quiescent current (60 µA). Both use SOT-223-4 packaging and maintain the same operating temperature range and automotive qualification. No circuit modifications are required.

Q: What are the key differences between TLE42662GSV33HTMA2 and TPS7B6933QDCYRQ1?

A: Both parts deliver 3.3V at 150mA in SOT-223-4 packaging with automotive qualification. TLE42662GSV33HTMA2 is an Infineon part with 1.1V dropout voltage and 60 µA quiescent current. TPS7B6933QDCYRQ1 is a Texas Instruments part with improved performance: 0.8V dropout voltage and 25 µA quiescent current. The TPS7B6933QDCYRQ1 has a lower maximum input voltage (40V vs. 45V). Selection depends on input voltage requirements and efficiency priorities.

Q: Are both substitutes suitable for automotive applications?

A: Yes. Both TLE42662GSV33HTMA2 and TPS7B6933QDCYRQ1 carry automotive grade classification and AEC-Q100 qualification, meeting automotive industry standards. Both are ROHS3 compliant.

Q: What is the packaging difference between the original part and substitutes?

A: All three parts use SOT-223-4 package (TO-261-4, TO-261AA). The original TLE4266-2GS V33 packaging is not specified in detail. TLE42662GSV33HTMA2 is supplied in Tape & Reel format. TPS7B6933QDCYRQ1 is supplied in Cut Tape & Digi-Reel® format. Both packaging formats are standard for surface-mount production.

Q: Why is the original TLE4266-2GS V33 marked as obsolete?

A: Product obsolescence is determined by the manufacturer. The TLE42662GSV33HTMA2 provides continuity as an active equivalent from the same manufacturer and series, ensuring design support and production availability.
