Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4250GHTSA1 is determined by strict equivalence across the following critical parameters:

• Output configuration (Positive) and type (Adjustable)
• Current output rating (50mA)
• Maximum input voltage (40V)
• Voltage dropout specification (0.3V @ 10mA)
• Operating temperature range (-40°C ~ 150°C)
• Package type (6-SMD (5 Leads), Gull Wing)
• Protection feature set (Over Current, Over Temperature, Reverse Polarity, Short Circuit)
• Control features (Enable function)

The TLE42502GHTSA1 meets all these criteria and qualifies as a direct substitute. This part maintains identical electrical specifications and mechanical compatibility while offering active product status and automotive-grade qualification.
