Substitute Part Grouping Explanation

Substitution eligibility for the TLE4254GSXUMA3 is determined by strict parameter matching across the following critical criteria:

Electrical Parameters (Must Match):

Output configuration: Positive
Output type: Adjustable
Number of regulators: 1
Maximum input voltage: 45V
Output current rating: 70mA
Quiescent current: 80 µA
Voltage dropout: 0.4V @ 70mA
PSRR: 60dB (100Hz)
Control features: Enable
Protection features: Over Temperature, Reverse Polarity, Short Circuit
Operating temperature range: -40°C ~ 150°C

Mechanical Parameters (Must Match):

Mounting type: Surface Mount

Engineering Selection Recommendations

All three substitute parts are electrically and mechanically equivalent to the TLE4254GSXUMA3. Selection should be based on the following factors:

Product Status: TLE4254GSXUMA4, TLE4254EJSXUMA2, and TLE4254EJAXUMA2 are all active products, ensuring long-term availability and manufacturing support compared to the obsolete TLE4254GSXUMA3.

Compliance: All substitute parts maintain automotive-grade classification and AEC-Q100 qualification, meeting the same reliability and qualification standards as the original part.

RoHS Compliance: The substitute parts are ROHS3 compliant, providing environmental compliance advantages over the main part where RoHS status was not specified.

Packaging Availability: TLE4254GSXUMA4 is available in Cut Tape and Digi-Reel® formats for lower-volume applications. TLE4254EJSXUMA2 and TLE4254EJAXUMA2 are available in Tape & Reel format for higher-volume production runs.

Frequently Asked Questions (FAQ)

Q: Can TLE4254GSXUMA4 be used as a direct replacement for TLE4254GSXUMA3?

A: Yes. Both parts share identical electrical specifications, automotive qualification, and AEC-Q100 certification. The primary difference is product status (active vs. obsolete) and packaging format. TLE4254GSXUMA4 is available in Cut Tape and Digi-Reel® formats, while TLE4254GSXUMA3 specifications do not specify packaging format.

Q: What is the difference between TLE4254EJSXUMA2 and TLE4254EJAXUMA2?

A: Both parts are parametrically equivalent with identical electrical performance. The difference lies in the supplier device package designation (PG-DSO-8 vs. PG-DSO-8-27) and inventory availability. Both are available in Tape & Reel format and are ROHS3 compliant.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All substitute parts carry automotive-grade classification and AEC-Q100 qualification, meeting the same automotive reliability standards as the original TLE4254GSXUMA3.

Q: Does the exposed pad on the package affect substitution compatibility?

A: No. The exposed pad is a thermal management feature that does not affect electrical functionality or pin compatibility. TLE4254GSXUMA4 does not specify an exposed pad in its package description, but this does not prevent its use as a substitute. PCB layout should accommodate the exposed pad where present for optimal thermal performance.

Q: What is the significance of the MSL rating?

A: All parts share MSL 3 (168 Hours) rating, indicating identical moisture sensitivity and storage requirements. This ensures consistent handling and storage protocols across all substitute options.
