Substitute Part Grouping Explanation

Substitution of the TLE4254GSXUMA1 is determined by strict equivalence across the following critical parameters:

Output configuration (Positive)
Output type (Adjustable)
Current rating (70mA)
Maximum input voltage (45V)
Dropout voltage (0.4V @ 70mA)
Quiescent current (80 µA)
PSRR performance (60dB @ 100Hz)
Operating temperature range (-40°C ~ 150°C)
Automotive grade and AEC-Q100 qualification
Package type (8-SOIC, PG-DSO-8)
Surface mount configuration

Two substitute parts meet these criteria: TLE4254GAXUMA4 and TLE4254GSXUMA4. Both maintain identical electrical performance and mechanical compatibility while differing in product status and packaging format.

Engineering Selection Recommendations

Both TLE4254GAXUMA4 and TLE4254GSXUMA4 are direct electrical and mechanical equivalents to the TLE4254GSXUMA1. Selection between these alternatives is based on product lifecycle and packaging requirements:

TLE4254GAXUMA4 is recommended for new designs requiring active product status from Infineon's current portfolio. This part carries active product status and features improved moisture sensitivity level (MSL 1, Unlimited) compared to the original part.

TLE4254GSXUMA4 maintains the OPTIREG™ series designation and is available in Cut Tape and Digi-Reel® packaging formats. This part also carries active product status and provides higher inventory availability (11,600 pcs) relative to other options.

Both substitute parts maintain full automotive grade qualification (AEC-Q100) and ROHS3 compliance, ensuring compatibility with automotive and industrial applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can TLE4254GAXUMA4 and TLE4254GSXUMA4 be used interchangeably with TLE4254GSXUMA1?

A: Yes. Both substitute parts are parametric equivalents with identical electrical specifications (70mA output, 45V maximum input, 0.4V dropout, 60dB PSRR) and mechanical compatibility (8-SOIC package, PG-DSO-8 supplier package). Pin configuration and functional behavior are identical.

Q: What is the difference between the substitute parts?

A: TLE4254GAXUMA4 offers improved moisture sensitivity (MSL 1 vs. MSL 3) and is available in standard packaging. TLE4254GSXUMA4 maintains the OPTIREG™ series designation, offers higher inventory availability, and is available in Cut Tape and Digi-Reel® formats. Both carry active product status.

Q: Are there packaging considerations for substitution?

A: The original TLE4254GSXUMA1 is supplied in Tape & Reel format. TLE4254GSXUMA4 is available in Cut Tape and Digi-Reel® formats, providing flexibility for different procurement and assembly workflows. TLE4254GAXUMA4 packaging format is not specified but maintains the same 8-SOIC physical package.

Q: Do the substitute parts meet automotive qualification requirements?

A: Yes. Both TLE4254GAXUMA4 and TLE4254GSXUMA4 are automotive grade with AEC-Q100 qualification, matching the original part's certification status.

Q: What is the impact of moisture sensitivity level differences?

A: TLE4254GAXUMA4 has MSL 1 (Unlimited storage), while TLE4254GSXUMA1 and TLE4254GSXUMA4 have MSL 3 (168 hours). MSL rating affects storage and handling requirements prior to assembly. Lower MSL values provide extended shelf life without special moisture control measures.
