Engineering Selection Recommendations

TLE42664GHTMA2 is the manufacturer-recommended substitute. This part maintains all critical electrical specifications while offering improved performance characteristics: reduced quiescent current (60 µA vs. 400 µA), lower supply current (4 mA vs. 15 mA), and enhanced PSRR (68dB vs. 54dB). The TLE42664GHTMA2 includes short-circuit protection in addition to the standard protection suite. Critically, this part carries Active product status, ensuring long-term availability and supply chain stability. The maximum input voltage is 40V, which is acceptable for applications not requiring the full 45V input range of the original part.

TLE42344GHTMA1 is a parametric equivalent substitute. This part matches the TLE42364GHTMA1 across all core electrical parameters, including the 45V maximum input voltage, 400 µA quiescent current, and 54dB PSRR. Both parts share Last Time Buy status, indicating similar end-of-life timelines. The TLE42344GHTMA1 is suitable for direct replacement in applications where the original part's full electrical specification range is required.

Frequently Asked Questions (FAQ)

Q: Can TLE42664GHTMA2 be used as a direct replacement for TLE42364GHTMA1?

A: Yes. The TLE42664GHTMA2 meets all critical substitution criteria: identical 5V output, 100mA current capability, 0.5V dropout specification, and PG-SOT223-4 package. The 40V maximum input voltage is the only parameter difference; applications operating below 40V input will experience no functional change. The improved quiescent current and PSRR represent performance enhancements.

Q: What is the difference between TLE42664GHTMA2 and TLE42344GHTMA1?

A: TLE42664GHTMA2 offers lower power consumption (60 µA Iq vs. 400 µA) and better noise rejection (68dB PSRR vs. 54dB), with Active product status ensuring continued availability. TLE42344GHTMA1 maintains identical electrical performance to the original TLE42364GHTMA1 but carries Last Time Buy status. Selection depends on power budget requirements and supply chain longevity needs.

Q: Are all three parts in the same package?

A: Yes. All three parts use the PG-SOT223-4 package (TO-261-4, TO-261AA designation), ensuring identical PCB footprint and mounting compatibility.

Q: Do these parts require design validation before substitution?

A: All substitute parts maintain automotive-grade qualification (AEC-Q100) and identical operating temperature ranges (-40°C to 150°C). Substitution is valid within the specified electrical parameter ranges. Applications requiring the full 45V input range must use TLE42364GHTMA1 or TLE42344GHTMA1.

Q: What is the inventory status of these parts?

A: TLE42364GHTMA1 has 946 units in stock (Last Time Buy status). TLE42664GHTMA2 has 10,400 units available (Active status), providing superior supply continuity. TLE42344GHTMA1 has 1,614 units in stock (Last Time Buy status).
