TLE42642GHTSA2 Equivalent & Substitute Parts

Part Overview

The TLE42642GHTSA2 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for positive fixed 5V output applications with 150mA current capacity. This automotive-grade component operates across an extended temperature range of -40°C to 150°C and includes integrated protection features for over-current, over-temperature, and short-circuit conditions. The part is actively produced and maintains full AEC-Q100 automotive qualification status. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, packaging preferences, or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

The TLE42642GHTSA2 has one identified parametric equivalent: TLE42642GHTMA1. Substitution eligibility is determined by the following criteria:

• Identical output voltage specification (5V fixed)
• Identical output current rating (150mA)
• Identical maximum input voltage (45V)
• Identical voltage dropout characteristic (0.5V @ 100mA)
• Identical package type (PG-SOT223-4)
• Identical automotive qualification (AEC-Q100)
• Identical protection feature set (Over Current, Over Temperature, Short Circuit)
• Identical operating temperature range (-40°C to 150°C)

The primary difference between these parts is the packaging format: TLE42642GHTSA2 is supplied in Cut Tape (CT) & Digi-Reel® format, while TLE42642GHTMA1 is supplied in Tape & Reel (TR) format. This distinction affects handling and assembly processes but does not alter electrical or thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Both TLE42642GHTSA2 and TLE42642GHTMA1 maintain active product status and full AEC-Q100 automotive qualification. Selection between these parts should be based on packaging and supply requirements:

• TLE42642GHTSA2 is appropriate for applications requiring Cut Tape or Digi-Reel® packaging formats, typically suited for lower-volume production or manual assembly processes.
• TLE42642GHTMA1 is appropriate for high-volume automated assembly operations utilizing standard Tape & Reel (TR) packaging.

Both parts satisfy identical electrical specifications, thermal performance, and protection requirements. The quiescent current difference of 10 µA between the two variants (60 µA vs. 70 µA) is negligible for most applications and does not affect functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can TLE42642GHTMA1 be used as a direct replacement for TLE42642GHTSA2?

A: Yes. Both parts are electrically and mechanically equivalent. The difference is packaging format only. TLE42642GHTMA1 uses standard Tape & Reel (TR) packaging, while TLE42642GHTSA2 uses Cut Tape & Digi-Reel® format. PCB footprint and soldering requirements are identical.

Q: What is the significance of the quiescent current difference?

A: TLE42642GHTSA2 specifies 60 µA quiescent current, while TLE42642GHTMA1 specifies 70 µA. This 10 µA difference is within normal manufacturing tolerance and does not affect circuit performance or thermal characteristics in typical applications.

Q: Are both parts suitable for automotive applications?

A: Yes. Both parts carry AEC-Q100 automotive qualification and are rated for the extended temperature range of -40°C to 150°C, meeting automotive reliability and environmental stress requirements.

Q: What packaging considerations apply when substituting between these parts?

A: TLE42642GHTSA2 in Cut Tape format is suitable for manual pick-and-place or lower-volume assembly. TLE42642GHTMA1 in Tape & Reel format is optimized for automated high-speed assembly equipment. Verify that your assembly process supports the selected packaging format.

Q: Do both parts have identical protection features?

A: Yes. Both parts include over-current, over-temperature, and short-circuit protection. Protection thresholds and response characteristics are identical.
