Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE4290DATMA1 is determined by the following critical parameters:

• Fixed output voltage of 5V
• Output current capability of 450mA or greater
• Maximum input voltage of 40V or higher
• TO-252-5 / DPAK package compatibility
• Automotive grade with AEC-Q100 qualification
• Operating temperature range of -40°C to 150°C
• Surface mount mounting type
• ROHS3 compliance

The three identified substitutes meet these core electrical and mechanical requirements while offering active product status and improved availability compared to the obsolete TLE4290DATMA1.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain full electrical and mechanical compatibility with the TLE4290DATMA1 within the specified parameter constraints. Selection among these alternatives should be based on the following factors:

TLS850C2TEV50ATMA1 (Infineon): Offers the highest output current capability at 500mA with significantly reduced quiescent current of 30 µA, providing improved power efficiency. Maintains Infineon OPTIREG™ series continuity. Maximum input voltage is 40V, which is acceptable for most applications within the 42V specification.

TLE4275QKVURQ1 (Texas Instruments): Provides exact output current matching at 450mA with identical dropout voltage characteristics. Maintains 42V maximum input voltage specification. Quiescent current of 200 µA is comparable to the original part.

NCV4275CDT50RKG (onsemi): Delivers 450mA output current with the lowest quiescent current at 150 µA among the three alternatives. Maintains full 42V input voltage specification and includes reset control functionality.

All three parts carry automotive grade designation with AEC-Q100 qualification, ROHS3 compliance, and unlimited moisture sensitivity level (MSL 1), ensuring suitability for automotive applications requiring long-term reliability.

Frequently Asked Questions (FAQ)

Q: Can TLS850C2TEV50ATMA1 be used as a direct replacement despite the 40V maximum input voltage versus the original 42V specification?

A: The TLS850C2TEV50ATMA1 operates at a maximum input voltage of 40V compared to the TLE4290DATMA1's 42V. This substitute is compatible for applications where the actual input voltage does not exceed 40V. System design review is necessary to confirm input voltage operating conditions.

Q: What are the key differences in protection features among the substitute parts?

A: The TLE4290DATMA1 includes over-current, over-temperature, reverse polarity, and short-circuit protection with power good and delay control features. TLS850C2TEV50ATMA1 provides over-current and over-temperature protection with reset output control. TLE4275QKVURQ1 includes over-current, over-temperature, and reverse polarity protection. NCV4275CDT50RKG provides over-temperature, reverse polarity, and short-circuit protection with reset control. Application-specific protection requirements should guide selection.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use TO-252-5 / DPAK (4 Leads + Tab) packaging, ensuring mechanical and thermal compatibility with the original TLE4290DATMA1. Pinout compatibility must be verified during circuit board layout review.

Q: What is the significance of the quiescent current differences among the substitutes?

A: Quiescent current values range from 30 µA (TLS850C2TEV50ATMA1) to 230 µA (TLE4290DATMA1). Lower quiescent current reduces standby power consumption. Selection depends on application power budget requirements and duty cycle characteristics.

Q: Do all substitute parts meet automotive qualification requirements?

A: All three substitute parts carry automotive grade designation with AEC-Q100 qualification, ROHS3 compliance, and REACH unaffected status, meeting automotive industry standards equivalent to the original TLE4290DATMA1.
