TLE4250GNTSA1 Equivalent & Substitute Parts

Part Overview

The TLE4250GNTSA1 is a linear voltage regulator IC from Infineon Technologies designed for positive adjustable output applications. This Surface Mount device delivers 50mA output current with a maximum dropout voltage of 0.3V at 10mA, suitable for low-power regulation circuits requiring adjustable voltage output with integrated protection features.

The TLE4250GNTSA1 carries a "Not For New Designs" product status. This designation indicates the part is no longer recommended for new circuit designs. Identifying equivalent substitute parts ensures design continuity, maintains supply chain flexibility, and enables transition to actively supported alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4250GNTSA1 is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive) and type (Adjustable)
• Single regulator topology
• Maximum input voltage (40V)
• Output current capability (50mA)
• Voltage dropout specification (0.3V @ 10mA)
• Quiescent current (20 µA)
• Operating temperature range (-40°C ~ 150°C)
• Surface Mount packaging in 6-SMD (5 Leads), Gull Wing configuration
• Supplier device package designation (PG-SCT595-5-1)
• Protection features (Over Current, Over Temperature, Reverse Polarity, Short Circuit)
• RoHS3 compliance

The TLE42502GHTSA1 meets all these criteria and qualifies as a parametric equivalent substitute.

Engineering Selection Recommendations

The TLE42502GHTSA1 is the recommended substitute for the TLE4250GNTSA1 based on the following engineering criteria:

The TLE42502GHTSA1 maintains full parametric equivalence across all critical electrical specifications including output configuration, current rating, voltage dropout, and operating temperature range. Both parts share identical package geometry and pinout (PG-SCT595-5-1), enabling direct board-level substitution without layout modifications.

The TLE42502GHTSA1 offers superior product lifecycle status as an Active part, eliminating obsolescence risk associated with the "Not For New Designs" designation of the original part. The substitute carries Automotive grade qualification with AEC-Q100 certification, providing enhanced reliability assurance suitable for demanding applications.

The TLE42502GHTSA1 demonstrates improved moisture handling with MSL 1 (Unlimited) rating compared to MSL 3 (168 Hours) of the original part, reducing storage and handling constraints during manufacturing.

Minor parameter variations exist in Current - Supply (Max) specification (5 mA versus 3 mA) and PSRR performance (48dB versus 60dB at 100Hz). These differences do not affect functional equivalence for standard adjustable regulator applications within the specified electrical operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the TLE42502GHTSA1 be used as a direct replacement for the TLE4250GNTSA1 on existing circuit boards?

A: Yes. Both parts share identical electrical specifications for output configuration, current rating, voltage dropout, and operating temperature. The package geometry and pinout (PG-SCT595-5-1, 6-SMD 5 Leads, Gull Wing) are identical, enabling direct substitution without PCB layout changes or design modifications.

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

A: The primary differences are product status and qualification level. The TLE42502GHTSA1 is an Active part with Automotive grade and AEC-Q100 qualification, while the TLE4250GNTSA1 is designated "Not For New Designs." The TLE42502GHTSA1 also features improved moisture sensitivity (MSL 1 versus MSL 3) and slightly higher maximum supply current (5 mA versus 3 mA). PSRR performance differs at 48dB versus 60dB at 100Hz.

Q: Are there any application restrictions when using the TLE42502GHTSA1 as a substitute?

A: No application restrictions exist based on the provided electrical and mechanical parameters. Both parts operate identically across the specified voltage, current, and temperature ranges. The automotive qualification of the substitute part does not impose additional constraints on standard industrial or consumer applications.

Q: How do the moisture sensitivity levels affect component handling?

A: The TLE42502GHTSA1 carries MSL 1 (Unlimited) rating, meaning it has no time-to-moisture-sensitivity restrictions during storage and handling. The original TLE4250GNTSA1 carries MSL 3 (168 Hours), requiring controlled storage conditions and limiting shelf life after packaging. The substitute part offers superior handling flexibility in manufacturing environments.

Q: Is the TLE42502GHTSA1 suitable for new design implementations?

A: Yes. The TLE42502GHTSA1 carries Active product status and is recommended for new designs. Its Automotive grade qualification and AEC-Q100 certification provide long-term availability assurance and enhanced reliability documentation suitable for production implementations.
