TLE4254GAXUMA3 Equivalent & Substitute Parts

Part Overview

The TLE4254GAXUMA3 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for positive adjustable output applications with 70mA current capability. This component is classified as a Power Management PMIC and is currently marked as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity, production planning, and system maintenance. The availability of active alternatives ensures uninterrupted supply chain access for applications requiring this regulator's electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4254GAXUMA3 is determined by strict electrical and mechanical parameter matching across the TLE4254 product family. All substitute parts maintain identical core specifications: positive adjustable output configuration, 70mA output current, 45V maximum input voltage, 0.4V maximum dropout voltage at 70mA, 80µA quiescent current, automotive grade qualification (AEC-Q100), and 8-SOIC surface mount packaging. The substitute parts differ primarily in product status (active vs. obsolete), packaging format (tape & reel, cut tape, or standard), and compliance certifications (RoHS3 status and moisture sensitivity levels). These variations do not affect electrical interchangeability but influence supply chain availability, procurement logistics, and long-term reliability assurance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—TLE4254GAXUMA4, TLE4254EJAXUMA2, and TLE4254GSXUMA4—are electrically and mechanically interchangeable with the obsolete TLE4254GAXUMA3 based on identical core electrical parameters and automotive-grade AEC-Q100 qualification.

TLE4254GAXUMA4 is the primary direct substitute. It maintains active product status, achieves ROHS3 compliance, and offers superior moisture sensitivity rating (MSL 1 vs. MSL 3), providing extended shelf life and reduced handling risk. Standard packaging format supports typical procurement workflows.

TLE4254EJAXUMA2 is the manufacturer-recommended alternative. It retains active product status and ROHS3 compliance while offering tape & reel packaging suitable for high-volume automated assembly. The exposed pad variant (PG-DSO-8-27) provides enhanced thermal performance for applications requiring improved heat dissipation. MSL 3 rating matches the original part specification.

TLE4254GSXUMA4 is the parametric equivalent with highest inventory availability. It maintains all electrical specifications and automotive qualification while offering cut tape and Digi-Reel® packaging options for flexible procurement. ROHS3 compliance and MSL 3 rating align with production requirements.

Selection should prioritize TLE4254GAXUMA4 for standard applications, TLE4254EJAXUMA2 for high-volume production requiring tape & reel format, and TLE4254GSXUMA4 when maximum inventory availability is critical.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically identical to the TLE4254GAXUMA3?

A: Yes. All substitute parts maintain identical electrical specifications: 70mA output current, 45V maximum input voltage, 0.4V maximum dropout voltage, 80µA quiescent current, 60dB PSRR at 100Hz, and identical protection features (over temperature, reverse polarity, short circuit). They are direct electrical replacements.

Q: What is the difference between the packaging formats offered?

A: TLE4254GAXUMA4 uses standard packaging. TLE4254EJAXUMA2 is supplied in tape & reel format optimized for automated pick-and-place assembly in high-volume production. TLE4254GSXUMA4 offers cut tape and Digi-Reel® options for flexible procurement. All use identical 8-SOIC surface mount packages with 0.154" width.

Q: Does the exposed pad variant (TLE4254EJAXUMA2) affect PCB layout?

A: The exposed pad in the PG-DSO-8-27 package provides improved thermal performance through enhanced heat dissipation to the PCB. PCB layout should include thermal vias connected to ground or a thermal plane if maximum thermal performance is required. Standard 8-SOIC layouts remain compatible.

Q: What is the significance of MSL ratings?

A: MSL (Moisture Sensitivity Level) indicates shelf life and handling requirements. TLE4254GAXUMA4 with MSL 1 (unlimited shelf life) offers superior storage stability compared to MSL 3 parts (168-hour limit after moisture exposure). For applications with extended storage or challenging environmental conditions, MSL 1 is preferred.

Q: Are all parts AEC-Q100 qualified for automotive applications?

A: Yes. All substitute parts carry AEC-Q100 automotive qualification and operate across -40°C to 150°C temperature range, meeting automotive-grade reliability standards.

Q: Can I mix different substitute part numbers in the same production batch?

A: Electrical interchangeability is confirmed across all substitutes. However, procurement and quality assurance procedures should maintain consistent part number usage within a single production lot to ensure traceability and simplify supply chain documentation.
