TLE4269GXUMA2 Equivalent & Substitute Parts

Part Overview

The TLE4269GXUMA2 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed to deliver a fixed 5V output at 100mA. This automotive-grade component features integrated protection against over-temperature, reverse polarity, and short-circuit conditions, with a maximum input voltage of 45V and a dropout voltage of 0.5V at full load. The device is currently in Last Time Buy status, making identification of suitable substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4269GXUMA2 is determined by the following critical parameters:

• Fixed output voltage of 5V
• Automotive-grade qualification (AEC-Q100)
• Maximum input voltage tolerance of 45V
• Dropout voltage specification of 0.5V @ 100mA
• Operating temperature range of -40°C ~ 150°C
• ROHS3 compliance and REACH unaffected status

The TLE42994GMXUMA3 qualifies as a manufacturer-recommended substitute because it maintains all core electrical specifications (5V fixed output, 45V max input, 0.5V dropout, identical temperature range, and automotive qualification). While the substitute offers enhanced performance characteristics (150mA output current versus 100mA, lower quiescent current, and additional control features), these represent functional improvements rather than deviations from the original specification envelope.

Parameter Comparison

Engineering Selection Recommendations

The TLE42994GMXUMA3 is the manufacturer-recommended substitute for the TLE4269GXUMA2. Both devices maintain identical automotive qualification (AEC-Q100) and regulatory compliance (ROHS3, REACH unaffected). The substitute is currently in Active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the original part.

The primary design consideration is package footprint: the substitute uses a 14-SOIC package versus the 8-SOIC of the original. PCB layout modifications are required to accommodate this change. The substitute's enhanced current capability (150mA versus 100mA) and significantly lower quiescent current (1 µA versus 300 µA) provide functional improvements suitable for applications where the original 100mA specification is adequate.

Frequently Asked Questions (FAQ)

Q: Can the TLE42994GMXUMA3 directly replace the TLE4269GXUMA2 without design changes?

A: Electrical substitution is valid; however, the package change from 8-SOIC to 14-SOIC requires PCB layout modification. Pin-to-pin compatibility does not exist due to the different package formats.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the TLE4269GXUMA2 and TLE42994GMXUMA3 carry AEC-Q100 automotive qualification and operate across the identical temperature range of -40°C ~ 150°C.

Q: What is the significance of the output current difference (100mA vs. 150mA)?

A: The TLE42994GMXUMA3 provides 50% higher output current capacity. For applications requiring only 100mA, the substitute operates well within its rating. The lower quiescent current (1 µA versus 300 µA) offers improved efficiency in low-power standby scenarios.

Q: Are there regulatory or compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, with identical ECCN and HTSUS classifications.

Q: What control features differ between these regulators?

A: The TLE4269GXUMA2 includes Reset control. The TLE42994GMXUMA3 adds Enable control in addition to Reset, providing more flexible power sequencing options in system designs.
