TPS767D301PWPRG4 Equivalent & Substitute Parts

Part Overview

The TPS767D301PWPRG4 is a linear voltage regulator IC from Texas Instruments designed for positive adjustable (fixed) output applications. This dual-output 1A regulator operates with input voltages up to 10V and provides output voltage options of 3.3V or 1.5V to 5.5V adjustable range. The device integrates enable and reset control features alongside over-current, over-temperature, and reverse-polarity protection. Currently discontinued at DiGi Electronics, alternative equivalent parts are available to maintain design continuity and ensure supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

TPS767D301PWPR (MFR Recommended Substitute): This part is the primary substitute for the discontinued TPS767D301PWPRG4. It maintains identical electrical and mechanical specifications with active product status at Texas Instruments. The TPS767D301PWPR offers superior inventory availability (10200 units) and flexible packaging options (Cut Tape and Digi-Reel). Both parts share ROHS3 compliance and identical MSL ratings. This substitute is suitable for direct replacement in existing designs without circuit or layout modifications.

TPS767D301QPWPRQ1 (Parametric Equivalent): This part provides parametric equivalence with automotive-grade qualification (AEC-Q100) and automotive temperature range certification. The TPS767D301QPWPRQ1 maintains all electrical and mechanical specifications identical to the main part. The higher MSL rating (3 vs. 2) reflects automotive-grade moisture sensitivity requirements. This substitute is appropriate for applications requiring automotive-grade components or AEC-Q100 qualification. Standard industrial applications should prioritize the TPS767D301PWPR unless automotive specifications are mandated.

Frequently Asked Questions (FAQ)

Q: Can TPS767D301PWPR be used as a direct replacement for TPS767D301PWPRG4? A: Yes. Both parts are electrically and mechanically identical across all critical parameters including output configuration, voltage ratings, current capacity, protection features, and package specifications. No circuit redesign or board layout modification is required.

Q: What is the difference between TPS767D301PWPR and TPS767D301QPWPRQ1? A: The primary differences are grade classification and qualification status. TPS767D301QPWPRQ1 is automotive-grade with AEC-Q100 qualification, while TPS767D301PWPR is standard industrial-grade. Both maintain identical electrical and mechanical specifications. The automotive variant has a higher MSL rating (3 vs. 2). Select based on application requirements: industrial applications use TPS767D301PWPR; automotive applications use TPS767D301QPWPRQ1.

Q: Are packaging options interchangeable between substitutes? A: Yes. Both substitute parts offer Cut Tape (CT) and Digi-Reel packaging options, providing flexibility for different procurement and assembly workflows. The 28-PowerTSSOP package dimensions remain constant across all variants.

Q: Do all parts meet RoHS compliance requirements? A: Yes. The main part and both substitutes are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for electronic component manufacturing and distribution.

Q: Which substitute should be selected for new designs? A: For new industrial designs, TPS767D301PWPR is recommended due to active product status and superior inventory availability. For automotive applications or designs requiring AEC-Q100 qualification, TPS767D301QPWPRQ1 is the appropriate selection.
