Key Parameters

Substitute Part Grouping Explanation

Substitution for the TLE4291EXUMA1 is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 450mA
• Maximum input voltage of 42V
• Voltage dropout specification of 0.5V @ 300mA
• Identical control features (Enable, Reset, Watchdog)
• Identical protection features (Over Current, Over Temperature, Reverse Polarity, Short Circuit)
• Operating temperature range of -40°C ~ 150°C
• Automotive grade with AEC-Q100 qualification
• 14-LSSOP package with exposed pad
• ROHS3 compliance

The TLE4291EXUMA2 meets all these criteria and is classified as a parametric equivalent within the TLE4291 base product family.

Parameter Comparison

Engineering Selection Recommendations

The TLE4291EXUMA2 is the direct substitute for the discontinued TLE4291EXUMA1. Both parts are manufactured by Infineon Technologies within the same OPTIREG™ series and share identical electrical and mechanical specifications. The TLE4291EXUMA2 maintains active product status and full availability, ensuring supply chain continuity.

Both parts carry automotive grade qualification with AEC-Q100 certification, meeting the same reliability and quality standards. ROHS3 compliance is maintained across both variants. The identical package footprint (14-LSSOP with exposed pad) and pinout enable direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the TLE4291EXUMA2 be used as a direct replacement for the TLE4291EXUMA1?

A: Yes. The TLE4291EXUMA2 is a parametric equivalent with identical electrical specifications, control features, protection features, operating temperature range, package, and automotive qualifications. Direct substitution is supported without circuit design changes.

Q: What is the difference between the TLE4291EXUMA1 and TLE4291EXUMA2?

A: The primary difference is product status. The TLE4291EXUMA1 is discontinued, while the TLE4291EXUMA2 is active. The suffix designations (EXUMA1 vs. EXUMA2) indicate different manufacturing batches or revisions within the same base product family, but all electrical and mechanical parameters remain identical.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the TLE4291EXUMA1 and TLE4291EXUMA2 carry automotive grade classification and AEC-Q100 qualification, meeting automotive reliability and quality standards.

Q: Is the package footprint identical between these parts?

A: Yes. Both parts use the 14-LSSOP package with 0.154" width (3.90mm) and exposed pad. PCB layouts and component placement are fully compatible.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected. They carry identical environmental and regulatory compliance status.
