TLE4263G Equivalent & Substitute Parts

Part Overview

The TLE4263G is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed to deliver a fixed 5V output at 200mA. This automotive-grade component features integrated reset and watchdog control functions, along with comprehensive protection mechanisms including over-temperature, reverse polarity, and short-circuit protection. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4263G is determined by strict equivalence across the following electrical and mechanical parameters:

• Output voltage specification (5V fixed)
• Output current capability (200mA minimum)
• Input voltage tolerance (45V maximum)
• Voltage dropout characteristics (0.5V @ 150mA)
• Quiescent current (50 µA)
• Control feature set (Reset and Watchdog functions)
• Protection mechanisms (Over Temperature, Reverse Polarity, Short Circuit)
• Operating temperature range (-40°C to 150°C)
• Automotive qualification (AEC-Q100)
• Base product family (TLE4263 series)

The substitute part TLE4263GXUMA2 maintains electrical equivalence across all specified parameters. Package configuration differences (20-SOIC versus 8-SOIC) represent the primary distinction and must be evaluated against PCB layout constraints and mechanical assembly requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the TLE4263G and TLE4263GXUMA2 are classified as obsolete products. Selection between these parts must be based on PCB layout and mechanical assembly constraints, as the primary difference is package configuration.

The TLE4263G utilizes a 20-SOIC package (7.50mm width), while the TLE4263GXUMA2 uses an 8-SOIC package (3.90mm width). The 8-SOIC variant offers reduced board footprint and may be preferred for space-constrained applications. Both parts maintain identical electrical specifications, control features, and protection mechanisms.

Both parts carry AEC-Q100 automotive qualification and ROHS3 compliance status (where applicable). Moisture sensitivity level remains constant at MSL 3 (168 Hours) for both variants, requiring equivalent handling and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can TLE4263GXUMA2 directly replace TLE4263G in existing designs?

A: Electrical substitution is valid across all specified parameters. However, the package difference (20-SOIC versus 8-SOIC) requires PCB layout verification. Pin configuration and footprint compatibility must be confirmed before implementation.

Q: What is the primary difference between these substitute parts?

A: The TLE4263GXUMA2 features a smaller 8-SOIC package compared to the 20-SOIC package of the TLE4263G. All electrical characteristics, output specifications, and protection features remain identical.

Q: Are both parts suitable for automotive applications?

A: Both the TLE4263G and TLE4263GXUMA2 are automotive-grade components qualified to AEC-Q100 standards and operate across the -40°C to 150°C temperature range required for automotive environments.

Q: What handling precautions apply to these components?

A: Both parts carry Moisture Sensitivity Level 3 (168 Hours). Standard ESD protection and dry storage conditions are required. Reflow soldering processes must comply with IPC standards for MSL 3 components.

Q: Are there additional substitute variants within the TLE4263 family?

A: The TLE4263 base product family includes variants TLE42632ESXUMA1 and TLE4263GSXUMA1, which maintain the same electrical specifications and automotive qualification as the primary substitute part.
