TLE42762DVATMA1 Equivalent & Substitute Parts

Part Overview

The TLE42762DVATMA1 is a linear voltage regulator IC from Infineon Technologies' OPTIREG™ series, designed for positive adjustable output applications with 400mA current capability in a TO-252-5 surface mount package. This automotive-grade component (AEC-Q100 qualified) has been discontinued at DiGi Electronics, necessitating identification of equivalent and substitute parts for ongoing design requirements and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLE42762DVATMA1 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Output Configuration: Positive
• Current - Output: 400mA
• Voltage - Input (Max): 40V minimum
• Voltage Dropout (Max): 0.5V @ 250mA maximum
• Package / Case: TO-252-5 (DPAK)
• Operating Temperature: -40°C ~ 150°C
• Grade: Automotive
• Qualification: AEC-Q100

Allowable Variation Parameters:

• Output Type: Adjustable or Fixed (both acceptable for circuit redesign)
• Voltage - Output (Min/Fixed): 2.5V or higher (adjustable range or fixed value)
• Current - Quiescent (Iq): Minor variations acceptable
• Control Features: Inhibit or Enable (functional equivalence)
• Protection Features: Subset or superset of original features acceptable

The three identified substitutes meet these criteria with varying degrees of direct equivalence.

Parameter Comparison

Engineering Selection Recommendations

TLE42764DVATMA1 (Direct Manufacturer Equivalent)

This Infineon part is the primary substitute for the discontinued TLE42762DVATMA1. Both devices share identical electrical specifications across all critical parameters: 400mA output current, 40V maximum input voltage, 0.5V dropout voltage, and adjustable output range (2.5V to 20V). The only functional difference is the control feature (Enable versus Inhibit), which represents a design-level choice rather than a compatibility issue. With 17,500 units in active inventory and Active product status, this part ensures long-term supply continuity. Both parts carry identical automotive qualification (AEC-Q100) and RoHS3 compliance.

TLE4276DVATMA2 (Parametric Equivalent)

This alternative Infineon part provides identical electrical performance to the original TLE42762DVATMA1, including matching quiescent current (200 µA) and control features (Inhibit). The part maintains all critical specifications: 400mA output, 40V input maximum, adjustable 2.5V to 20V output, and 0.5V dropout voltage. With 94,085 units in inventory and Active status, this part offers superior availability. The primary distinction is the supplier device package designation (PG-TO252-5-1 versus PG-TO252-5), which reflects packaging variation within the same physical TO-252-5 form factor. Automotive grade and AEC-Q100 qualification are maintained.

NCV4276CDT50RKG (Cross-Manufacturer Substitute)

This onsemi part represents a functional substitute requiring circuit redesign due to its fixed 5V output configuration, contrasting with the adjustable output of the original part. The device maintains critical electrical parameters: 400mA output current, 45V maximum input voltage (exceeding the original 40V), 0.5V dropout voltage, and identical operating temperature range. PSRR performance is superior at 70dB versus 54dB. Over-current protection is not included in this part's feature set. Automotive qualification (AEC-Q100) and RoHS3 compliance are maintained. This substitute is applicable only when a fixed 5V output meets circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can TLE42764DVATMA1 directly replace TLE42762DVATMA1 without circuit modification?

A: Yes. Both parts are Infineon OPTIREG™ series devices with identical electrical specifications for output current (400mA), input voltage range (40V max), dropout voltage (0.5V @ 250mA), and adjustable output range (2.5V to 20V). The control feature difference (Enable versus Inhibit) does not prevent direct substitution at the component level, though circuit control logic may require evaluation.

Q: What is the difference between TLE42764DVATMA1 and TLE4276DVATMA2?

A: Both parts are functionally equivalent with identical electrical performance. The primary difference is inventory availability (17,500 units versus 94,085 units) and supplier device package designation. TLE4276DVATMA2 offers superior stock levels for high-volume production requirements.

Q: Can NCV4276CDT50RKG be used as a drop-in replacement?

A: No. The NCV4276CDT50RKG is a fixed 5V output regulator, whereas the original TLE42762DVATMA1 provides adjustable output (2.5V to 20V). This part requires circuit redesign and is applicable only when a fixed 5V output is acceptable for the application. All other electrical parameters (400mA output, 0.5V dropout, operating temperature) are compatible.

Q: Are all three substitutes automotive-qualified?

A: Yes. All substitute parts carry AEC-Q100 qualification and automotive-grade designation, matching the original TLE42762DVATMA1. All are ROHS3 compliant and suitable for automotive applications.

Q: What is the package compatibility across these parts?

A: All four parts use the TO-252-5 (DPAK with 4 leads plus tab) surface mount package. Physical and electrical pin configurations are compatible across all parts, enabling direct PCB-level substitution without layout modification.

Q: Which substitute offers the best long-term availability?

A: TLE4276DVATMA2 provides the highest inventory level (94,085 units) with Active product status, ensuring sustained availability for production continuity. TLE42764DVATMA1 (17,500 units) is the secondary choice for Infineon-preferred designs.

Q: Does NCV4276CDT50RKG offer any performance advantages?

A: The NCV4276CDT50RKG provides superior PSRR performance (70dB versus 54dB at 100Hz) and higher maximum input voltage rating (45V versus 40V). However, these advantages are offset by the fixed output configuration and absence of over-current protection, limiting its applicability to designs requiring fixed 5V regulation.
