Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE42672GATMA2 is determined by strict equivalence across the following critical parameters:

• Output voltage configuration: Fixed 5V positive output
• Output current capability: 400mA minimum
• Input voltage tolerance: Maximum 40V
• Voltage dropout specification: 0.6V @ 400mA
• Quiescent current: 4 mA
• PSRR performance: 54dB (100Hz)
• Control features: Inhibit and Reset functionality
• Protection features: Over-current, over-temperature, reverse polarity, short circuit, and transient voltage protection
• Package type: TO-263-8 D2PAK (7 Leads + Tab)
• Automotive qualification: AEC-Q100 compliance required
• Temperature range: -40°C to 150°C

The TLE42672GATMA1 qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The TLE42672GATMA1 is the direct substitute for the obsolete TLE42672GATMA2. Both devices are manufactured by Infineon Technologies and share identical electrical specifications, control features, and protection mechanisms. The TLE42672GATMA1 maintains active product status, ensuring continued availability and supply chain support. Both parts meet automotive-grade requirements with AEC-Q100 qualification and comply with RoHS3 and REACH regulatory standards.

The primary difference between these parts is packaging format: the TLE42672GATMA2 is supplied in bulk format, while the TLE42672GATMA1 is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TLE42672GATMA1 directly replace the TLE42672GATMA2 in existing designs?

A: Yes. The TLE42672GATMA1 is electrically and functionally identical to the TLE42672GATMA2. Both devices deliver 5V at 400mA with identical dropout voltage, quiescent current, PSRR, and protection features. The TO-263-8 D2PAK package pinout is identical, enabling direct PCB-level substitution.

Q: What is the significance of the product status difference?

A: The TLE42672GATMA2 is classified as obsolete, indicating Infineon has discontinued production and support. The TLE42672GATMA1 maintains active status, ensuring ongoing manufacturing, technical support, and supply availability. For new designs and long-term production, the TLE42672GATMA1 is the recommended selection.

Q: Are there packaging considerations when switching from TLE42672GATMA2 to TLE42672GATMA1?

A: The TLE42672GATMA2 is supplied in bulk packaging, while the TLE42672GATMA1 is supplied in Tape & Reel (TR) format. This affects procurement logistics and automated assembly processes but does not impact the component's electrical performance or PCB integration.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the TLE42672GATMA2 and TLE42672GATMA1 are automotive-grade components qualified to AEC-Q100 standards. Both comply with RoHS3 and REACH regulatory requirements, making them suitable for automotive applications requiring regulatory compliance.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by fixed 5V output voltage, 400mA output current, 40V maximum input voltage, 0.6V dropout voltage at 400mA, 4mA quiescent current, 54dB PSRR at 100Hz, identical control features (Inhibit, Reset), and identical protection mechanisms (over-current, over-temperature, reverse polarity, short circuit, and transient voltage protection).
