Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4268GSXUMA2 is determined by the following critical parameters:

• Fixed output voltage of 5V
• Positive output configuration
• 8-SOIC surface mount package (0.154", 3.90mm Width)
• Automotive grade qualification (AEC-Q100)
• Operating temperature range of -40°C to 150°C
• Maximum input voltage of 45V
• ROHS3 compliance

The TLE42632ESXUMA1 qualifies as a manufacturer-recommended substitute. Both devices share identical package geometry, voltage specifications, temperature range, automotive qualification, and compliance certifications. The substitute part provides enhanced current capacity (180mA versus 150mA) and improved quiescent current performance, making it a direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

The TLE42632ESXUMA1 is the manufacturer-recommended substitute for the obsolete TLE4268GSXUMA2. Both devices maintain identical automotive qualification (AEC-Q100) and ROHS3 compliance status, ensuring regulatory and quality standards are preserved.

The substitute part is currently in active production with substantial inventory availability (15,940 pcs), compared to the obsolete status of the main part. The TLE42632ESXUMA1 provides superior electrical performance through increased output current capacity (180mA versus 150mA) and reduced quiescent current consumption (400 µA versus 450 µA), while maintaining full package and thermal compatibility.

Selection of the TLE42632ESXUMA1 is appropriate for new designs and replacement applications where the enhanced current capability and active product status provide long-term supply security and performance benefits.

Frequently Asked Questions (FAQ)

Q: Can the TLE42632ESXUMA1 be used as a direct replacement for the TLE4268GSXUMA2?

A: Yes. Both devices share identical package geometry (8-SOIC), fixed 5V output voltage, maximum input voltage (45V), operating temperature range (-40°C to 150°C), automotive grade qualification, and ROHS3 compliance. The substitute part is the manufacturer-recommended equivalent.

Q: What are the key differences between these parts?

A: The TLE42632ESXUMA1 provides higher output current capacity (180mA versus 150mA), lower quiescent current (400 µA versus 450 µA), and is in active production status. The voltage dropout specification is slightly higher (0.6V versus 0.5V at 150mA). The substitute part includes an Enable control feature in addition to Reset and Watchdog functions.

Q: Are there any package compatibility concerns?

A: No. Both parts use the identical 8-SOIC (0.154", 3.90mm Width) package. PCB layouts and footprints require no modification for substitution.

Q: Does the substitute part maintain automotive qualification?

A: Yes. The TLE42632ESXUMA1 carries AEC-Q100 qualification and ROHS3 compliance, identical to the main part. Automotive application requirements are fully satisfied.

Q: Why is the main part listed as obsolete?

A: The TLE4268GSXUMA2 has been discontinued by Infineon Technologies. The TLE42632ESXUMA1 represents the active product line continuation with enhanced specifications and ongoing manufacturing support.
