Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4285GHTSA1 is determined by the following critical parameters that must remain compatible:

• Fixed output voltage of 5V
• Surface mount package configuration (6-SMD, 5 Leads, Gull Wing)
• Automotive-grade qualification (AEC-Q100)
• Operating temperature range (-40°C to 150°C)
• Positive output configuration
• Linear regulator topology within the OPTIREG™ series

The TLE42962GV50HTSA1 qualifies as a direct substitute based on these parameters. While this substitute offers enhanced specifications (30mA output current versus 15mA, improved dropout voltage of 0.3V @ 20mA versus 1.1V @ 10mA, and additional protection features), it maintains full compatibility with the original part's core electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

The TLE42962GV50HTSA1 is the qualified substitute for the TLE4285GHTSA1. Both components maintain identical output voltage specifications, package configurations, and automotive-grade certifications required for AEC-Q100 applications. The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the Last Time Buy status of the original part.

The TLE42962GV50HTSA1 provides enhanced performance characteristics including doubled output current capacity (30mA versus 15mA) and significantly reduced dropout voltage (0.3V @ 20mA versus 1.1V @ 10mA). These improvements offer design flexibility for applications requiring higher current delivery or lower input voltage margins. Both parts comply with ROHS3 and REACH requirements and operate across the full automotive temperature range.

Frequently Asked Questions (FAQ)

Q: Can the TLE42962GV50HTSA1 directly replace the TLE4285GHTSA1 in existing designs?

A: Yes. Both parts share identical output voltage (5V), package configuration (6-SMD, 5 Leads, Gull Wing), and automotive qualification (AEC-Q100). The substitute part is pin-compatible and functionally compatible for all applications designed for the original part.

Q: What are the key differences between these two regulators?

A: The primary differences are output current capacity (30mA versus 15mA), dropout voltage performance (0.3V @ 20mA versus 1.1V @ 10mA), maximum input voltage (45V versus 42V), and product status (Active versus Last Time Buy). The substitute offers superior electrical performance while maintaining full compatibility.

Q: Are there any thermal or reliability concerns when substituting these parts?

A: Both parts operate across -40°C to 150°C and carry AEC-Q100 automotive qualification. Thermal performance is comparable given identical package types and similar quiescent current specifications (150 µA versus 170 µA).

Q: Does the substitute part require PCB layout modifications?

A: No. The TLE42962GV50HTSA1 uses the identical 6-SMD (5 Leads), Gull Wing package as the original part, requiring no changes to PCB footprints or assembly processes.

Q: What protection features does the substitute part provide?

A: The TLE42962GV50HTSA1 includes Over Current, Over Temperature, Reverse Polarity, and Short Circuit protection. The original TLE4285GHTSA1 provides Over Temperature and Short Circuit protection.
