Key Parameters

Substitute Part Grouping Explanation

The TLE4284DVATMA1 qualifies as a manufacturer-recommended substitute based on the following alignment criteria:

Matching Parameters:

• Identical manufacturer (Infineon Technologies)
• Same series (OPTIREG™)
• Identical package and case (TO-252-3, DPAK, SC-63)
• Identical mounting type (Surface Mount)
• Identical input voltage maximum (40V)
• Identical dropout voltage specification (1.4V @ 1A)
• Identical operating temperature range (-40°C ~ 150°C)
• Identical automotive grade and AEC-Q100 qualification
• Identical RoHS3 compliance status

Functional Difference: The substitute part features adjustable output voltage (1.25V to 38.6V) versus the fixed 5V output of the main part. This adjustability allows the TLE4284DVATMA1 to be configured for 5V operation through external resistor networks while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TLE4284DVATMA1 is the manufacturer-recommended substitute for the TLE4284DV50ATMA1. Both devices maintain identical automotive-grade specifications and AEC-Q100 qualification, ensuring compliance with automotive reliability standards. The substitute part's Active product status provides extended availability compared to the main part's Last Time Buy designation.

The primary design consideration is the output voltage configuration. The main part delivers a fixed 5V output, while the substitute requires external resistor divider networks to establish the 5V output voltage. This substitution is valid only when the design can accommodate the adjustable output topology and associated external components.

Both parts share identical electrical performance characteristics including dropout voltage, input voltage rating, output current capacity, and operating temperature range. The substitute's lower quiescent current (120 µA versus 1.6 mA) represents an additional benefit for power-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the TLE4284DVATMA1 directly replace the TLE4284DV50ATMA1 without circuit modifications?

A: No. The TLE4284DVATMA1 requires external resistor networks to set the output voltage to 5V, whereas the TLE4284DV50ATMA1 provides fixed 5V output. Circuit redesign is necessary to implement the adjustable output configuration.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the TLE4284DV50ATMA1 and TLE4284DVATMA1 carry automotive-grade designation with AEC-Q100 qualification and operate across the identical temperature range of -40°C to 150°C.

Q: What is the packaging difference between these parts?

A: Both parts use identical TO-252-3 (DPAK) surface mount packaging with the same pin configuration and footprint. The main part is supplied in Cut Tape (CT) & Digi-Reel® format, while the substitute is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Why does the substitute have lower quiescent current?

A: The TLE4284DVATMA1's adjustable output topology results in 120 µA quiescent current compared to the fixed-output main part's 1.6 mA. This difference is inherent to the device architectures and does not affect substitution validity.

Q: Are there compliance or regulatory differences between these parts?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and ECCN/HTSUS classifications. Regulatory and environmental compliance is equivalent.
