TLE4276GV50ATMA2 Equivalent & Substitute Parts

Part Overview

The TLE4276GV50ATMA2 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for automotive applications. This positive fixed output regulator delivers 400mA at 5V with integrated protection features including over-current, over-temperature, reverse polarity, and short-circuit protection. The device is qualified to AEC-Q100 automotive standards and operates across the extended temperature range of -40°C to 150°C.

The TLE4276GV50ATMA2 is currently discontinued at DiGi Electronics, necessitating identification of equivalent substitute parts that maintain electrical and mechanical compatibility for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitution of the TLE4276GV50ATMA2 is determined by strict equivalence across the following critical parameters:

Output voltage and current rating (5V, 400mA)
Input voltage specification (40V maximum)
Dropout voltage performance (0.5V @ 250mA)
Protection feature set (over-current, over-temperature, reverse polarity, short-circuit)
Automotive qualification and AEC-Q100 certification
Operating temperature range (-40°C ~ 150°C)
RoHS3 compliance status

The identified substitute parts maintain identical electrical specifications and automotive-grade qualification. Differences exist only in packaging configuration and product availability status, which are secondary considerations for functional equivalence.

Engineering Selection Recommendations

Both TLE4276GV50ATMA3 and TLE4276GV50ATMA4 are direct functional equivalents to the discontinued TLE4276GV50ATMA2, with identical electrical specifications and automotive-grade AEC-Q100 qualification.

TLE4276GV50ATMA3 is recommended as the primary substitute. It maintains the same packaging format (Cut Tape & Digi-Reel®) as the original part and carries active product status with higher inventory availability (6562 units in stock).

TLE4276GV50ATMA4 serves as an alternative substitute with active product status and adequate inventory (797 units in stock). The packaging difference (Tape & Reel format) does not affect electrical performance but may require adjustment to assembly line handling procedures.

Both substitutes maintain full compliance with RoHS3 and REACH requirements, ensuring regulatory continuity for automotive applications.

Frequently Asked Questions (FAQ)

Q: Are TLE4276GV50ATMA3 and TLE4276GV50ATMA4 electrically identical to TLE4276GV50ATMA2?

A: Yes. Both substitute parts deliver identical electrical performance: 5V fixed output at 400mA, 40V maximum input voltage, 0.5V dropout voltage at 250mA, and the complete protection feature set (over-current, over-temperature, reverse polarity, short-circuit). All three parts are AEC-Q100 qualified automotive-grade devices operating across -40°C to 150°C.

Q: What is the difference between the substitute parts?

A: The primary difference is packaging configuration. TLE4276GV50ATMA3 is supplied in Cut Tape & Digi-Reel® format, while TLE4276GV50ATMA4 is supplied in Tape & Reel format. Both are surface-mount devices with identical pinout and electrical specifications. The packaging difference affects supply chain logistics and assembly line compatibility but not circuit performance.

Q: Can I use either substitute interchangeably with the original part?

A: Yes, from an electrical and functional standpoint. Both substitutes are pin-compatible and electrically equivalent. Selection between them depends on your assembly process requirements and packaging preferences. Verify that your pick-and-place equipment supports the selected packaging format.

Q: Are the substitute parts still in production?

A: Yes. Both TLE4276GV50ATMA3 and TLE4276GV50ATMA4 carry active product status, ensuring continued availability and long-term supply security for production applications.

Q: Do the substitutes maintain automotive compliance?

A: Yes. Both substitute parts retain AEC-Q100 automotive qualification, RoHS3 compliance, and REACH unaffected status, matching the regulatory requirements of the original TLE4276GV50ATMA2.
