TLE4252DNTMA1 Equivalent & Substitute Parts

Part Overview

The TLE4252DNTMA1 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for positive adjustable output applications with 250mA current capability in a TO-252-5 surface mount package. This component is classified as obsolete, making identification of compatible substitutes essential for ongoing production and maintenance applications. The part operates across automotive-grade specifications with AEC-Q100 qualification, supporting input voltages up to 40V with integrated protection features including over-temperature, reverse polarity, and short-circuit protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE4252DNTMA1 is determined by strict equivalence across the following critical parameters:

Electrical Performance: Output configuration (positive), output type (adjustable), current rating (250mA), maximum input voltage (40V), dropout voltage (0.6V @ 200mA), quiescent current (150 µA), and PSRR (60dB @ 100Hz) must remain identical.

Mechanical Compatibility: Package type (TO-252-5 / DPAK with 4 leads + tab), surface mount mounting type, and pin configuration must match exactly.

Environmental & Compliance: Operating temperature range (-40°C ~ 150°C), automotive grade classification, and AEC-Q100 qualification are mandatory for equivalent substitution.

Series Continuity: Parts must belong to the OPTIREG™ series from Infineon Technologies to maintain design consistency.

The TLE4252DATMA1 qualifies as a parametric equivalent based on identical electrical specifications, mechanical packaging, and automotive compliance requirements. The primary distinction is product status: TLE4252DNTMA1 is obsolete while TLE4252DATMA1 is active, with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The TLE4252DATMA1 is the direct substitute for the obsolete TLE4252DNTMA1. Both parts maintain identical electrical performance, mechanical compatibility, and automotive-grade compliance specifications. Selection between these parts is determined by availability and product lifecycle status.

For new designs or production requiring active component support, the TLE4252DATMA1 is the appropriate choice, offering significantly higher inventory availability (1,000,300 pcs vs. 827 pcs) and active product status with ongoing manufacturer support. The TLE4252DATMA1 carries RoHS3 compliance certification, providing additional environmental regulatory alignment.

For legacy system maintenance or repair applications where the original TLE4252DNTMA1 specification must be maintained, the TLE4252DATMA1 provides complete functional and mechanical equivalence without design modification.

Both parts are qualified to AEC-Q100 automotive standards and maintain identical electrical characteristics across all specified parameters, ensuring direct substitution without circuit redesign or performance degradation.
