TLE7368EXUMA1 Equivalent & Substitute Parts

Part Overview

The TLE7368EXUMA1 is an automotive-grade power management integrated circuit (PMIC) designed for multi-output voltage regulation in automotive applications. This device features three independent outputs delivering 5V, 3.3V/2.6V, and 1.5V from a wide input voltage range of 4.5V to 45V. The component is qualified to AEC-Q100 automotive standards and housed in a 36-pin BSSOP package with exposed pad.

The TLE7368EXUMA1 carries an Obsolete product status, making it necessary to identify functionally equivalent alternatives for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility across input voltage specifications, output voltage levels, package form factor, and automotive qualification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE7368EXUMA1 is determined by strict alignment of the following critical parameters:

Electrical Compatibility Requirements:

• Input voltage range: 4.5V ~ 45V (must match)
• Number of outputs: 3 (must match)
• Output voltage configuration: Primary outputs at 5V and 3.3V/2.6V (must match); tertiary output tolerance within automotive specification limits
• Operating temperature range: -40°C ~ 150°C (must match)

Mechanical & Packaging Requirements:

• Package type: 36-BSSOP with exposed pad (must match)
• Mounting type: Surface Mount (must match)
• Supplier device package designation: PG-DSO-36 (must match)

Qualification & Compliance Requirements:

• Automotive grade classification (must match)
• AEC-Q100 qualification (must match)
• Moisture sensitivity level: MSL 3 (must match)
• REACH and ECCN status (must match)

The TLE7368EXUMA3 qualifies as a direct substitute based on identical electrical input/output specifications, package form factor, automotive qualification, and compliance certifications. The tertiary output voltage specification (1.3V vs. 1.5V) represents a minor variation within the TLE7368 product family design envelope and does not preclude substitution in applications where this output is not utilized or where the lower voltage is acceptable.

Parameter Comparison

Engineering Selection Recommendations

The TLE7368EXUMA1 is classified as Obsolete, indicating end-of-life status and unavailability for new procurement. The TLE7368EXUMA3 carries a Not For New Designs status, reflecting a later lifecycle phase within the TLE7368 product family.

Both devices maintain identical automotive qualification (AEC-Q100) and compliance certifications (REACH Unaffected, ECCN EAR99), ensuring regulatory equivalence for automotive applications. The electrical and mechanical specifications are aligned across input voltage handling, output configuration, operating temperature range, and package form factor.

Selection between these parts should be based on application-specific requirements for the tertiary output voltage (1.5V vs. 1.3V) and component availability. For applications where the tertiary output voltage specification is critical, design validation is necessary to confirm functional compatibility with the TLE7368EXUMA3 output level.

Frequently Asked Questions (FAQ)

Q: Can the TLE7368EXUMA3 directly replace the TLE7368EXUMA1 in existing designs?

A: The TLE7368EXUMA3 is electrically and mechanically compatible with the TLE7368EXUMA1 across primary output specifications (5V and 3.3V/2.6V), package form factor (36-BSSOP PG-DSO-36), and automotive qualification (AEC-Q100). The tertiary output voltage differs (1.3V vs. 1.5V). Substitution is valid when the tertiary output is not utilized or when the lower voltage is acceptable to the application circuit.

Q: What are the key compatibility criteria for substitution?

A: Substitution eligibility is determined by: (1) identical input voltage range (4.5V ~ 45V), (2) matching output count and primary voltage levels, (3) identical package type and pin configuration (36-BSSOP PG-DSO-36), (4) matching automotive grade and AEC-Q100 qualification, and (5) equivalent moisture sensitivity and compliance certifications.

Q: Are there any package or mounting differences between these parts?

A: Both the TLE7368EXUMA1 and TLE7368EXUMA3 use the 36-BSSOP package with exposed pad, identical pin pitch (0.295", 7.50mm width), and surface mount technology. No PCB layout or assembly process modifications are required for substitution.

Q: What is the significance of the product status difference (Obsolete vs. Not For New Designs)?

A: Obsolete status indicates the TLE7368EXUMA1 is no longer manufactured or available for procurement. Not For New Designs status for the TLE7368EXUMA3 indicates limited availability and that Infineon does not recommend this part for new design starts. Both statuses reflect end-of-life positioning within the product family. For long-term production continuity, evaluation of alternative PMIC solutions from current product lines is recommended.

Q: Are moisture sensitivity and handling requirements identical?

A: Both parts carry MSL 3 (168 Hours) classification, requiring identical moisture control procedures during storage, handling, and assembly. No changes to component storage or reflow processes are necessary.
