Key Parameters

Substitute Part Grouping Explanation

The TLE4699GMXUMA1 qualifies as a direct substitute based on the following critical parameters:

• Fixed 5V output voltage matching the main part
• Identical 200mA output current rating
• Identical 45V maximum input voltage specification
• Matching automotive grade and AEC-Q100 qualification
• Identical operating temperature range (-40°C to 150°C)
• ROHS3 compliance and equivalent regulatory status
• Same series family (OPTIREG™) ensuring functional compatibility

The primary distinction is packaging: TLE4263GSXUMA1 uses 8-SOIC while TLE4699GMXUMA1 uses 14-SOIC. Both packages maintain the same 0.154" (3.90mm) width, allowing substitution in designs with adequate PCB layout space. The TLE4699GMXUMA1 carries Active product status, making it suitable for new designs and ongoing production.

Parameter Comparison

Engineering Selection Recommendations

The TLE4699GMXUMA1 is the qualified substitute for TLE4263GSXUMA1 applications. Selection between these parts depends on design constraints:

Use TLE4699GMXUMA1 when:

• New designs or production continuation is required (Active product status)
• PCB layout accommodates 14-pin SOIC packaging
• Lower dropout voltage (0.35V vs 0.5V) provides system margin benefit
• Higher PSRR (65dB vs 54dB) improves noise performance
• Enable control feature is required for power sequencing

Retain TLE4263GSXUMA1 only when:

• Existing PCB layout is constrained to 8-pin SOIC footprint
• Watchdog functionality is specifically required
• Lower quiescent current (50µA vs 100µA) is critical for battery-powered applications
• Existing inventory supports production timelines

Both parts maintain identical automotive qualification (AEC-Q100), compliance certifications (ROHS3), and regulatory status, ensuring equivalent reliability and supply chain eligibility.

Frequently Asked Questions (FAQ)

Q: Can TLE4699GMXUMA1 directly replace TLE4263GSXUMA1 on existing PCBs?

A: Direct PCB replacement requires layout modification. While both packages maintain 0.154" width, the pin count differs (8 vs 14). The 14-pin package requires a larger footprint. Schematic review is necessary to confirm all control features (Enable vs Watchdog) align with system requirements.

Q: What are the key electrical differences between these parts?

A: The TLE4699GMXUMA1 offers improved performance: 0.35V dropout versus 0.5V, and 65dB PSRR versus 54dB. The TLE4263GSXUMA1 draws lower quiescent current (50µA vs 100µA). Both deliver identical 5V/200mA output and support -40°C to 150°C operation.

Q: Why is TLE4263GSXUMA1 marked "Not For New Designs"?

A: This status indicates Infineon has transitioned the product line. The TLE4699GMXUMA1 represents the active alternative within the OPTIREG™ series, offering enhanced specifications and ongoing manufacturing support.

Q: Are both parts automotive qualified?

A: Yes. Both TLE4263GSXUMA1 and TLE4699GMXUMA1 carry AEC-Q100 qualification and automotive-grade designation, meeting identical reliability and testing standards.

Q: What control features differ between these regulators?

A: TLE4263GSXUMA1 includes Reset and Watchdog functions. TLE4699GMXUMA1 includes Enable and Reset functions. System design must accommodate this functional difference during substitution.
