Substitute Part Grouping Explanation

Substitution eligibility for the TLE4253GSXUMA2 is determined by strict equivalence across the following critical parameters:

Output configuration and type (Positive, Adjustable)
Current output rating (250mA)
Maximum input voltage (40V)
Voltage dropout specification (0.6V @ 200mA)
Operating temperature range (-40°C ~ 150°C)
Package type (8-SOIC, 0.154", 3.90mm Width)
Automotive grade and AEC-Q100 qualification
Protection features (Over Temperature, Reverse Polarity, Short Circuit)
Control features (Enable)

The TLE4253GSXUMA4 meets all these criteria and is classified as a parametric equivalent. The primary distinction is packaging format (Tape & Reel vs. standard packaging) and product status (Active vs. Discontinued).

Engineering Selection Recommendations

The TLE4253GSXUMA4 is a direct parametric equivalent to the TLE4253GSXUMA2 across all electrical and mechanical specifications. Both devices share identical performance characteristics, automotive qualification, and protection features. The primary differences are product status and packaging format.

For new designs or ongoing procurement, the TLE4253GSXUMA4 is the recommended selection due to its Active product status and current availability. This ensures long-term supply chain continuity and manufacturer support.

The TLE4253GSXUMA4 is supplied in Tape & Reel format, which is standard for high-volume production environments. The increased Moisture Sensitivity Level (MSL 3 vs. MSL 1) requires adherence to standard moisture handling procedures during storage and assembly, consistent with industry practices for surface mount components.

Both parts maintain full compliance with ROHS3, REACH, and automotive AEC-Q100 qualification requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLE4253GSXUMA4 be used as a direct replacement for the TLE4253GSXUMA2?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. They share the same output current (250mA), input voltage rating (40V), dropout voltage (0.6V @ 200mA), operating temperature range (-40°C ~ 150°C), package type (8-SOIC), and automotive qualification (AEC-Q100).

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The TLE4253GSXUMA2 is discontinued, while the TLE4253GSXUMA4 is active. The TLE4253GSXUMA4 is supplied in Tape & Reel format with MSL 3 moisture sensitivity, compared to standard packaging with MSL 1 for the TLE4253GSXUMA2.

Q: Are there any compatibility concerns when switching from TLE4253GSXUMA2 to TLE4253GSXUMA4?

A: No compatibility concerns exist at the electrical or mechanical level. PCB layout and schematic connections remain identical. The Tape & Reel packaging format is standard for production environments and requires only standard moisture handling procedures during component storage and assembly.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the TLE4253GSXUMA2 and TLE4253GSXUMA4 are qualified to AEC-Q100 automotive standards and are rated for the automotive grade. Both maintain full compliance with ROHS3 and REACH requirements.

Q: What is the significance of the MSL rating difference?

A: The TLE4253GSXUMA4 has MSL 3 (168 hours), meaning the component must be used within 168 hours of opening the moisture barrier bag. The TLE4253GSXUMA2 has MSL 1 (unlimited), requiring no time restriction. This is a standard consideration for surface mount components and does not affect electrical performance or reliability when proper handling procedures are followed.
