Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLE4276DVATMA1 are identified based on strict electrical and mechanical parameter compatibility within the automotive power management IC category. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

• Output configuration (Positive)
• Output type (Adjustable)
• Voltage output range (2.5V to 20V minimum/maximum)
• Current output capability (400mA minimum)
• Voltage dropout specification (0.5V @ 250mA maximum)
• Operating temperature range (-40°C ~ 150°C minimum)

Mechanical Compatibility Criteria:

• Package type (TO-252-5 / DPAK with 4 Leads + Tab)
• Surface mount mounting type
• Automotive grade qualification (AEC-Q100)
• RoHS3 compliance

Identified Substitute Parts:

1. TLE4276DVATMA2 (Infineon Technologies) – Direct manufacturer equivalent with identical electrical specifications and packaging. Active product status.

2. NCV4276BDTADJRKG (onsemi) – Cross-manufacturer substitute meeting all electrical and mechanical parameters. Manufacturer-recommended alternative with enhanced PSRR performance.

Parameter Comparison

Engineering Selection Recommendations

TLE4276DVATMA2 (Infineon Technologies): This part is the primary substitute for the discontinued TLE4276DVATMA1. It maintains identical electrical specifications, packaging, and automotive qualification. The part is currently in active production status with substantial inventory availability (94,085 pcs). This option is suitable for both replacement and new design applications requiring continuity with the original specification.

NCV4276BDTADJRKG (onsemi): This cross-manufacturer substitute meets all critical electrical and mechanical compatibility requirements. The part features enhanced PSRR performance (70dB vs. 54dB at 100Hz) and slightly higher maximum input voltage rating (45V vs. 40V). However, the product status is listed as "Not For New Designs," making it suitable only for replacement applications in existing designs where component qualification has already been established. The part carries full automotive grade and AEC-Q100 qualification.

Both substitute parts maintain compliance with RoHS3 and REACH requirements, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can TLE4276DVATMA2 be used as a direct replacement for TLE4276DVATMA1?

A: Yes. TLE4276DVATMA2 is a direct equivalent with identical electrical specifications, output voltage range (2.5V to 20V), current capability (400mA), dropout voltage (0.5V @ 250mA), operating temperature range (-40°C to 150°C), and TO-252-5 DPAK packaging. Both parts are AEC-Q100 qualified automotive-grade components with ROHS3 compliance.

Q: What are the differences between TLE4276DVATMA1 and NCV4276BDTADJRKG?

A: Both parts share identical core electrical specifications for output voltage range, current output, dropout voltage, and operating temperature. The NCV4276BDTADJRKG offers enhanced PSRR performance (70dB vs. 54dB at 100Hz) and a higher maximum input voltage rating (45V vs. 40V). Both use the same TO-252-5 DPAK package and carry AEC-Q100 automotive qualification. The primary difference is manufacturer (onsemi vs. Infineon) and product lifecycle status.

Q: Is the TO-252-5 package compatible across all three parts?

A: Yes. All three parts use the TO-252-5 DPAK package with 4 leads plus tab, ensuring mechanical and electrical pin compatibility. Surface mount assembly processes and PCB layouts designed for one part are compatible with the others.

Q: Can NCV4276BDTADJRKG be used in new designs?

A: NCV4276BDTADJRKG is designated "Not For New Designs" by the manufacturer. It is suitable only for replacement applications in existing designs. For new designs, TLE4276DVATMA2 is the recommended choice due to its active product status.

Q: Are all substitute parts automotive-grade qualified?

A: Yes. All three parts carry automotive grade classification and AEC-Q100 qualification, meeting automotive industry reliability and quality standards. All are ROHS3 compliant and REACH unaffected.

Q: What is the key parameter that determines substitutability for this regulator?

A: The critical parameters are output voltage adjustability range (2.5V to 20V), output current capability (400mA), dropout voltage specification (0.5V @ 250mA), and TO-252-5 DPAK package format. Parts meeting these specifications with matching automotive qualification are considered substitutable.
