Substitute Part Grouping Explanation

Substitute parts for the TLE4276GVATMA2 are classified based on electrical parameter compatibility and packaging considerations:

Parametric Equivalent (TLE4276GVATMA3): Maintains identical electrical specifications including output voltage range (2.5V–20V), output current (400mA), dropout voltage (0.5V @ 250mA), quiescent current (200 µA), PSRR (54dB @ 100Hz), protection features, and automotive qualification (AEC-Q100). Differs only in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Discontinued). Same package type (TO-263-5) and supplier device package (PG-TO263-5-1).

Direct Manufacturer Alternative (TLE4276GVATMA4): Shares the same base product number (TLE4276) and manufacturer (Infineon Technologies) with identical electrical performance parameters. Differs in package type (TO220-5 vs. TO-263-5), which affects PCB layout and thermal characteristics. Product status is Active.

Substitution eligibility is determined by:

• Identical output voltage range (2.5V–20V)
• Identical output current (400mA)
• Identical dropout voltage specification (0.5V @ 250mA)
• Identical quiescent current (200 µA)
• Identical PSRR (54dB @ 100Hz)
• Identical protection features (Over Current, Over Temperature, Reverse Polarity, Short Circuit)
• Identical automotive grade and AEC-Q100 qualification
• Identical control features (Inhibit)
• Compatible package footprint or acceptable PCB redesign

Parameter Comparison

Engineering Selection Recommendations

TLE4276GVATMA3 is the primary substitute for TLE4276GVATMA2. Both parts maintain identical electrical specifications, automotive qualification (AEC-Q100), and package footprint (TO-263-5). The TLE4276GVATMA3 is currently Active in product status with higher inventory availability (1,233 pcs vs. 700 pcs), making it the preferred choice for design continuity. Packaging format differs (Tape & Reel vs. bulk), which affects procurement logistics but not electrical or mechanical compatibility.

TLE4276GVATMA4 is an alternative when package redesign is acceptable. This part uses a TO220-5 package instead of TO-263-5, requiring PCB layout modification. The TO220-5 package offers different thermal and mechanical characteristics suitable for applications where through-hole or larger footprint mounting is preferred. Product status is Active with full availability.

Both substitutes maintain ROHS3 compliance, MSL Level 1, and identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001).

Frequently Asked Questions (FAQ)

Q: Can TLE4276GVATMA3 be used as a direct drop-in replacement for TLE4276GVATMA2?

A: Yes. Both parts share identical electrical specifications, package type (TO-263-5), and supplier device package (PG-TO263-5-1). The only difference is packaging format (Tape & Reel vs. bulk) and product status. No circuit redesign is required.

Q: What is the key difference between TLE4276GVATMA2 and TLE4276GVATMA4?

A: The primary difference is package type. TLE4276GVATMA2 uses TO-263-5 (surface mount, D2PAK), while TLE4276GVATMA4 uses TO220-5 (through-hole or surface mount). This affects PCB footprint, thermal dissipation path, and mounting method. Electrical specifications are identical based on the base product number TLE4276.

Q: Are all three parts automotive-qualified?

A: TLE4276GVATMA2 and TLE4276GVATMA3 are explicitly automotive-grade with AEC-Q100 qualification. TLE4276GVATMA4 specifications do not include automotive grade or AEC-Q100 qualification data in the provided parameters.

Q: What does "Parametric Equivalent" mean for TLE4276GVATMA3?

A: Parametric Equivalent indicates that TLE4276GVATMA3 maintains all critical electrical parameters (voltage range, current rating, dropout voltage, quiescent current, PSRR, protection features) identical to TLE4276GVATMA2. Differences are limited to packaging format and product lifecycle status.

Q: Can I use TLE4276GVATMA4 without modifying my PCB?

A: No. TLE4276GVATMA4 uses a different package type (TO220-5 vs. TO-263-5), requiring PCB footprint redesign. Electrical compatibility is maintained, but physical layout changes are necessary.

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

A: All three parts are ROHS3 compliant, MSL Level 1, and share identical regulatory classifications (ECCN: EAR99, HTSUS: 8542.39.0001). No compliance differences exist.

Q: Why is TLE4276GVATMA2 discontinued?

A: Product discontinuation information is provided by DiGi Electronics. TLE4276GVATMA3 and TLE4276GVATMA4 remain Active, ensuring continued supply availability.
