Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE42702AKSA1 is determined by the following critical parameters:

• Output voltage specification (5V fixed)
• Output current capability (650mA minimum)
• Input voltage range tolerance (42V maximum)
• Dropout voltage performance (0.7V @ 550mA)
• Quiescent current characteristics (1.5mA)
• Protection feature set (all six protection types required)
• Automotive qualification status (AEC-Q100)
• Operating temperature range (-40°C to 150°C)
• Regulatory compliance (ROHS3, REACH Unaffected)

The TLE42702GATMA1 qualifies as a direct substitute based on identical electrical specifications across all critical parameters. The primary distinction is packaging format: the original uses TO-220-5 through-hole mounting, while the substitute employs TO-263-5-1 surface-mount technology. Both variants share the same base product number (TLE42702) and are manufactured by Infineon Technologies within the OPTIREG™ series.

Parameter Comparison

Engineering Selection Recommendations

The TLE42702GATMA1 is the direct electrical equivalent for the obsolete TLE42702AKSA1. Both devices maintain identical performance specifications across all functional parameters and share AEC-Q100 automotive qualification.

The TLE42702GATMA1 holds active product status with Infineon Technologies, ensuring continued availability and manufacturing support. This substitute is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Selection between these parts depends on PCB design requirements. The original TLE42702AKSA1 uses through-hole TO-220-5 packaging suitable for through-hole assembly processes. The TLE42702GATMA1 employs surface-mount TO-263-5-1 packaging, appropriate for surface-mount technology (SMT) assembly. PCB layout, thermal management approach, and assembly process capabilities determine which package format is suitable for your application.

Frequently Asked Questions (FAQ)

Q: Can the TLE42702GATMA1 directly replace the TLE42702AKSA1 in existing designs?

A: Electrical substitution is complete. The TLE42702GATMA1 provides identical voltage regulation performance, current capacity, protection features, and automotive qualification. However, the packaging differs: TLE42702AKSA1 uses through-hole TO-220-5 mounting, while TLE42702GATMA1 uses surface-mount TO-263-5-1. PCB redesign is required if switching between through-hole and surface-mount assembly processes.

Q: What are the thermal considerations when switching packages?

A: Both packages are rated for the same operating temperature range (-40°C to 150°C). Thermal performance depends on PCB layout, copper area allocation, and heat dissipation design. Consult the respective device datasheets for thermal resistance specifications (junction-to-ambient and junction-to-case) specific to each package variant.

Q: Are there any compliance differences between these parts?

A: Both the TLE42702AKSA1 and TLE42702GATMA1 are ROHS3 compliant, REACH unaffected, and AEC-Q100 qualified for automotive applications. No compliance differences exist between the two variants.

Q: Why is the TLE42702AKSA1 marked as obsolete?

A: Product obsolescence reflects Infineon's manufacturing lifecycle decisions. The TLE42702GATMA1 remains in active production and provides equivalent functionality, making it the recommended path for new designs and ongoing supply requirements.

Q: What is the difference between the TO-220-5 and TO-263-5-1 packages?

A: TO-220-5 is a through-hole package with formed leads for insertion into PCB holes. TO-263-5-1 (D2PAK) is a surface-mount package with a metal tab for enhanced thermal dissipation. Package selection depends on assembly process capability and thermal management requirements of your application.
