TLE4268GSXUMA1 Equivalent & Substitute Parts

Part Overview

The TLE4268GSXUMA1 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for automotive applications. It provides a fixed 5V positive output with 180mA current capability in an 8-SOIC surface mount package. The device includes integrated protection features for over-current, over-temperature, reverse polarity, and short-circuit conditions, along with reset and watchdog control functions.

This part is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4268GSXUMA1 is determined by the following critical parameters:

• Fixed output voltage of 5V
• Output current rating of 180mA
• Maximum input voltage of 45V
• 8-SOIC surface mount package with 0.154" (3.90mm) width
• Automotive grade qualification with AEC-Q100 certification
• Operating temperature range of -40°C to 150°C
• ROHS3 compliance and equivalent moisture sensitivity level

The TLE42632ESXUMA1 meets all these core substitution criteria. While this substitute is an active product (versus the obsolete status of the main part), it maintains functional and electrical compatibility within the specified parameter envelope.

Parameter Comparison

Engineering Selection Recommendations

The TLE42632ESXUMA1 is the manufacturer-recommended substitute for the obsolete TLE4268GSXUMA1. Both devices maintain identical automotive qualification status (AEC-Q100) and comply with ROHS3 requirements. The substitute part is currently in active production with substantial inventory availability (15,940 pcs), ensuring supply chain continuity.

The TLE42632ESXUMA1 provides improved performance characteristics in certain areas: lower quiescent current (400 µA vs. 450 µA) and reduced maximum supply current (15 mA vs. 20 mA). The voltage dropout specification shows a marginal increase (0.6V vs. 0.5V at 150mA), which remains within acceptable tolerances for most 5V regulation applications. The substitute adds an Enable control feature not present in the original part.

Both devices are qualified for the same operating temperature range (-40°C to 150°C) and share identical package geometry, enabling direct PCB-level replacement without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TLE42632ESXUMA1 be used as a direct replacement for the TLE4268GSXUMA1?

A: Yes. Both parts share the same 5V fixed output voltage, 180mA current rating, 45V maximum input voltage, and 8-SOIC package footprint. Automotive qualification and AEC-Q100 certification are identical. The substitute is the manufacturer-recommended alternative.

Q: What are the key differences between these parts?

A: The TLE42632ESXUMA1 is an active product (versus obsolete status), offers lower quiescent and supply current consumption, and includes an additional Enable control feature. Voltage dropout increases marginally from 0.5V to 0.6V at 150mA. These differences do not affect functional compatibility in standard 5V regulation applications.

Q: Are there any package or pinout considerations?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) package. Verify pinout compatibility with your specific application schematic, as the addition of the Enable feature may require circuit design review.

Q: What is the inventory status of the substitute part?

A: The TLE42632ESXUMA1 has 15,940 pcs in stock as new original inventory, providing reliable supply availability compared to the obsolete TLE4268GSXUMA1.

Q: Are both parts compliant with automotive and environmental standards?

A: Yes. Both devices are automotive-grade, AEC-Q100 qualified, ROHS3 compliant, and carry identical moisture sensitivity levels (MSL 3, 168 hours). They meet equivalent environmental and regulatory requirements.
