TLE4254GAXUMA4 Equivalent & Substitute Parts

Part Overview

The TLE4254GAXUMA4 is a linear voltage regulator IC from Infineon Technologies' power management product line. This positive adjustable output regulator delivers 70mA with a maximum input voltage of 45V and features integrated protection against over-temperature, reverse polarity, and short circuit conditions. The device is qualified to AEC-Q100 automotive standards and operates across the temperature range of -40°C to 150°C. As an active product with established supply availability, alternative equivalent parts may be required for specific packaging formats, lead times, or inventory optimization in production environments.

Key Parameters

Substitute Part Grouping Explanation

The TLE4254GAXUMA4 has one parametric equivalent: TLE4254GSXUMA4. Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive)
• Output type (Adjustable)
• Number of regulators (1)
• Maximum input voltage (45V)
• Output current rating (70mA)
• Voltage dropout specification (0.4V @ 70mA)
• Quiescent current (80 µA)
• Protection features (Over Temperature, Reverse Polarity, Short Circuit)
• Operating temperature range (-40°C ~ 150°C)
• Automotive grade and AEC-Q100 qualification
• Package type (8-SOIC, PG-DSO-8)
• Regulatory compliance (ROHS3, REACH Unaffected)

The substitute part maintains identical electrical performance and mechanical compatibility while differing in packaging format (Cut Tape & Digi-Reel) and moisture sensitivity level classification.

Parameter Comparison

Engineering Selection Recommendations

Both the TLE4254GAXUMA4 and TLE4254GSXUMA4 are active products from Infineon Technologies with full AEC-Q100 automotive qualification and ROHS3 compliance. The parts are electrically and mechanically identical across all specified parameters. Selection between these parts should be based on packaging format requirements and moisture sensitivity handling procedures. The TLE4254GAXUMA4 features MSL 1 classification (unlimited moisture exposure tolerance), while the TLE4254GSXUMA4 carries MSL 3 classification (168-hour moisture exposure limit). Organizations with established moisture control protocols and bake-out procedures may utilize either part interchangeably. The TLE4254GSXUMA4 offers higher inventory availability (11,600 pcs) compared to the TLE4254GAXUMA4 (3,400 pcs).

Frequently Asked Questions (FAQ)

Q: Are TLE4254GAXUMA4 and TLE4254GSXUMA4 pin-for-pin compatible?

A: Yes. Both parts use the 8-SOIC (PG-DSO-8) package with identical pinout and electrical characteristics. Direct substitution on the PCB is supported without design modification.

Q: What is the difference between MSL 1 and MSL 3 classifications?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling. MSL 3 (168 Hours) specifies the component must be used within 168 hours of package opening under controlled humidity conditions, or the component must undergo a bake-out procedure before reflow soldering.

Q: Can I substitute TLE4254GSXUMA4 for TLE4254GAXUMA4 in automotive applications?

A: Yes. Both parts carry identical AEC-Q100 automotive qualification and meet all specified electrical and thermal requirements for automotive-grade applications.

Q: What packaging formats are available?

A: TLE4254GAXUMA4 is supplied in standard packaging format. TLE4254GSXUMA4 is available in Cut Tape (CT) and Digi-Reel® formats, offering flexibility for different assembly and inventory management workflows.

Q: Are there any performance differences between these parts?

A: No. Both parts deliver identical electrical performance: 70mA output current, 0.4V maximum dropout voltage at rated current, 80 µA quiescent current, and 60dB PSRR at 100Hz.
