Key Parameters

Substitute Part Grouping Explanation

The TLE42962GV50HTSA1 qualifies as a direct substitute based on the following alignment of critical parameters:

Substitution Criteria:

• Identical output voltage: 5V fixed
• Identical package type: 6-SMD (5 Leads), Gull Wing with PG-SCT595-5 supplier device package
• Identical series: OPTIREG™ from Infineon Technologies
• Identical operating temperature range: -40°C ~ 150°C
• Identical automotive grade and AEC-Q100 qualification
• Identical control features: Inhibit function
• Identical RoHS and REACH compliance status

Enhanced Specifications in Substitute: The TLE42962GV50HTSA1 provides higher output current (30mA vs. 15mA) and improved dropout voltage (0.3V @ 20mA vs. 1.1V @ 10mA), making it suitable for applications requiring greater current capacity while maintaining full backward compatibility in form factor and electrical interface.

Engineering Selection Recommendations

The TLE42962GV50HTSA1 is the recommended substitute for the TLE4286GHTSA1 based on the following engineering factors:

Product Status Alignment: The TLE4286GHTSA1 is in Last Time Buy status, indicating discontinued production. The TLE42962GV50HTSA1 maintains Active product status, ensuring long-term availability and supply chain continuity.

Compliance & Certification: Both parts maintain identical automotive-grade qualification (AEC-Q100) and ROHS3 compliance, meeting all regulatory requirements for automotive applications. No additional qualification or testing is required for substitution within the specified electrical parameters.

Electrical Compatibility: The substitute part operates within the same voltage specifications (5V output, -40°C ~ 150°C operating range) and maintains identical package geometry and pinout. The enhanced current capacity (30mA vs. 15mA) and improved dropout voltage provide design margin without requiring circuit modifications.

Protection Enhancement: The TLE42962GV50HTSA1 includes additional protection features (Over Current and Reverse Polarity protection) compared to the original part, providing improved robustness in automotive environments.

Frequently Asked Questions (FAQ)

Q: Can the TLE42962GV50HTSA1 be used as a direct replacement for the TLE4286GHTSA1 without PCB modifications?

A: Yes. Both parts share identical package type (6-SMD, Gull Wing), pinout configuration (PG-SCT595-5), and electrical interface specifications. No PCB layout changes are required for substitution.

Q: What are the key differences between these two parts?

A: The primary differences are output current capacity (30mA vs. 15mA), dropout voltage performance (0.3V @ 20mA vs. 1.1V @ 10mA), and protection features. The substitute includes Over Current and Reverse Polarity protection in addition to the original Over Temperature and Short Circuit protection.

Q: Is the higher quiescent current (170 µA vs. 100 µA) in the substitute part a concern?

A: The increase in quiescent current is 70 µA, which is negligible in most automotive applications. This trade-off is offset by improved dropout voltage and enhanced protection features.

Q: Are both parts qualified for automotive use?

A: Yes. Both the TLE4286GHTSA1 and TLE42962GV50HTSA1 carry automotive-grade designation and AEC-Q100 qualification, meeting automotive industry reliability and quality standards.

Q: What is the impact of the higher maximum input voltage (45V vs. 42V) in the substitute?

A: The increased input voltage rating provides additional design margin and compatibility with a broader range of automotive power supply configurations. This is a beneficial enhancement with no negative impact on existing designs.

Q: Can the substitute part handle higher current loads than the original?

A: Yes. The TLE42962GV50HTSA1 is rated for 30mA output current compared to 15mA for the TLE4286GHTSA1. Applications requiring current levels between 15mA and 30mA can utilize the substitute part's full capacity.
