Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4253EXUMA1 is determined by strict equivalence across the following critical parameters:

• Output configuration and type (Positive Adjustable)
• Current output rating (250mA)
• Maximum input voltage (40V)
• Voltage dropout specification (0.6V @ 200mA)
• Quiescent current (150 µA)
• PSRR performance (60dB @ 100Hz)
• Operating temperature range (-40°C ~ 150°C)
• Package type (8-SOIC with exposed pad)
• Automotive grade and AEC-Q100 qualification
• Control features (Enable function)
• Protection features (Over Temperature, Reverse Polarity, Short Circuit)

The TLE4253EXUMA2 meets all these criteria as a direct functional equivalent within the same OPTIREG™ series, differing only in packaging format and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The TLE4253EXUMA2 is the direct equivalent substitute for the TLE4253EXUMA1. Both parts maintain identical electrical and mechanical specifications, with the primary distinction being product lifecycle status. The TLE4253EXUMA1 carries a "Not For New Designs" classification, whereas the TLE4253EXUMA2 maintains active production status. Both parts satisfy automotive-grade requirements and hold AEC-Q100 qualification, ensuring compliance with automotive reliability standards. The packaging difference (Tape & Reel versus Cut Tape & Digi-Reel®) reflects only the supply format and does not affect functional performance or PCB integration. Selection between these parts should be based on supply chain availability and production continuity requirements.

Frequently Asked Questions (FAQ)

Q: Can TLE4253EXUMA2 be used as a direct replacement for TLE4253EXUMA1 in existing designs?

A: Yes. The TLE4253EXUMA2 is functionally identical to the TLE4253EXUMA1 across all electrical parameters, output characteristics, protection features, and operating specifications. Both parts use the same 8-SOIC package with exposed pad and require identical PCB layout and circuit design.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: These are supply format variations only. Tape & Reel packaging is continuous reel format suitable for high-volume automated assembly. Cut Tape & Digi-Reel® provides smaller quantity options with individual tape segments. The actual component and its performance characteristics remain unchanged.

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

A: No. Both TLE4253EXUMA1 and TLE4253EXUMA2 carry identical automotive-grade classification, AEC-Q100 qualification, ROHS3 compliance, and REACH unaffected status. Moisture sensitivity level (MSL 3, 168 hours) is also identical.

Q: Why is TLE4253EXUMA1 marked as "Not For New Designs"?

A: This classification indicates the part has reached end-of-life status in Infineon's product portfolio. The TLE4253EXUMA2 represents the active production equivalent and should be specified for new design implementations.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is valid when the following parameters match: output configuration (Positive Adjustable), current rating (250mA), maximum input voltage (40V), dropout voltage (0.6V @ 200mA), quiescent current (150 µA), PSRR (60dB @ 100Hz), operating temperature range (-40°C to 150°C), package type (8-SOIC with exposed pad), and protection features (Over Temperature, Reverse Polarity, Short Circuit).
