Substitute Part Grouping Explanation

Substitution eligibility for the TLE42644GHTMA1 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Fixed output voltage of 5V
• Output current rating of 100mA
• Maximum input voltage of 40V
• Maximum dropout voltage of 0.5V @ 100mA
• Positive output configuration
• Single regulator output

Mechanical Equivalence Criteria:

• Surface mount packaging in TO-261-4 or TO-261AA case
• PG-SOT223-4 supplier device package designation

Compliance Equivalence Criteria:

• Automotive grade classification
• AEC-Q100 qualification
• RoHS3 compliance
• Operating temperature range of -40°C to 150°C

Parts meeting all three equivalence categories are classified as parametric equivalents and direct substitutes. The TLE42644GHTSA3 satisfies all substitution criteria and is identified as a compatible alternative.

Parameter Comparison

Engineering Selection Recommendations

The TLE42644GHTSA3 is a direct parametric equivalent to the TLE42644GHTMA1 and qualifies as a substitute part based on the following engineering criteria:

Electrical Performance: Both parts deliver identical fixed 5V output at 100mA with matching input voltage tolerance (40V maximum), dropout voltage specification (0.5V @ 100mA), and protection feature sets. The TLE42644GHTSA3 exhibits a lower quiescent current of 60 µA compared to 70 µA in the TLE42644GHTMA1, representing an improvement in standby power consumption without affecting functional equivalence.

Mechanical Compatibility: Both parts utilize identical surface mount packaging (TO-261-4, TO-261AA) with PG-SOT223-4 supplier device package designation, ensuring direct PCB footprint compatibility and assembly process alignment.

Compliance and Certification: Both parts maintain automotive grade classification with AEC-Q100 qualification, RoHS3 compliance, and identical operating temperature range (-40°C to 150°C). These certifications confirm suitability for automotive and industrial applications with equivalent reliability standards.

Product Status: Both parts maintain active product status with Infineon Technologies, ensuring continued availability and manufacturing support.

Selection between these parts depends on inventory availability and supply chain requirements rather than functional or compliance differences.
