Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE4263GXUMA2 are identified based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output voltage: 5V fixed
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Input voltage rating: 45V maximum
• Operating temperature range: -40°C ~ 150°C
• Automotive grade with AEC-Q100 qualification
• ROHS3 compliance and equivalent regulatory status

Substitute Categories:

MFR Recommended Substitute: TLE42632ESXUMA1 represents the manufacturer-recommended alternative, offering active product status with enhanced protection features (over-current protection added) and improved quiescent current specification (400 µA). Output current is reduced to 180mA with slightly higher dropout voltage (0.6V @ 150mA).

Parametric Equivalent: TLE4263GSXUMA1 maintains identical electrical specifications to the main part (200mA output, 0.5V dropout, 50 µA quiescent current) with matching control features. This part carries "Not For New Designs" status and differs only in packaging format (Tape & Reel vs. standard packaging) and supplier device package designation (PG-DSO-8-16).

Parameter Comparison

Engineering Selection Recommendations

For New Production: TLE42632ESXUMA1 is the manufacturer-recommended substitute with active product status, ensuring long-term availability and supply chain stability. This part is qualified for new designs and carries full AEC-Q100 automotive certification. The 20mA reduction in output current (180mA vs. 200mA) and increased quiescent current (400 µA vs. 50 µA) must be evaluated against application load requirements. Enhanced over-current protection provides additional circuit safeguarding.

For Legacy System Support: TLE4263GSXUMA1 provides parametric equivalence with identical electrical performance (200mA output, 0.5V dropout, 50 µA quiescent current) and maintains all control features. The "Not For New Designs" status indicates this part is suitable for sustaining existing production runs and field replacements where electrical specifications must match the original component exactly. Packaging format differs (Tape & Reel) but maintains identical 8-SOIC physical dimensions.

Compliance Verification: All substitute parts maintain automotive-grade classification with AEC-Q100 qualification, ROHS3 compliance, and equivalent regulatory status (REACH Unaffected, EAR99 ECCN classification). Moisture sensitivity level remains constant at MSL 3 (168 Hours) across all variants.

Frequently Asked Questions (FAQ)

Q: Can TLE42632ESXUMA1 directly replace TLE4263GXUMA2 in existing designs?

A: TLE42632ESXUMA1 is the manufacturer-recommended substitute but introduces three specification changes: output current reduced from 200mA to 180mA, dropout voltage increased from 0.5V to 0.6V @ 150mA, and quiescent current increased from 50 µA to 400 µA. Applications requiring the full 200mA output or operating with tight power budgets must evaluate these differences against system requirements.

Q: What is the difference between TLE42632ESXUMA1 and TLE4263GSXUMA1?

A: TLE4263GSXUMA1 maintains identical electrical specifications to the original TLE4263GXUMA2 (200mA output, 0.5V dropout, 50 µA quiescent current). TLE42632ESXUMA1 offers manufacturer support with active product status but with reduced output current and increased quiescent current. TLE4263GSXUMA1 is designated "Not For New Designs" while TLE42632ESXUMA1 is qualified for new production.

Q: Are all substitute parts in the same physical package?

A: Yes. All three parts use the 8-SOIC (0.154", 3.90mm Width) package with identical physical dimensions. Packaging format differs (Cut Tape & Digi-Reel® for TLE42632ESXUMA1, Tape & Reel for TLE4263GSXUMA1), but this affects supply and handling only, not PCB layout or mechanical compatibility.

Q: Do substitute parts maintain automotive qualification?

A: Yes. Both TLE42632ESXUMA1 and TLE4263GSXUMA1 carry automotive-grade classification with AEC-Q100 qualification, matching the original part's certification level. Operating temperature range (-40°C ~ 150°C) and moisture sensitivity level (MSL 3, 168 Hours) remain unchanged.

Q: Which substitute should be selected for new automotive designs?

A: TLE42632ESXUMA1 is the appropriate choice for new designs, as it carries active product status and is explicitly qualified for new production. This ensures long-term component availability and manufacturer support. Verify that the 180mA output current and 400 µA quiescent current specifications meet application requirements.
