Key Parameters

Substitute Part Grouping Explanation

Substitution for the TPS78833DBVR is determined by the following critical parameters:

• Output voltage specification (3.3V fixed)
• Package compatibility (SOT-23-5)
• Output current capability (minimum 150mA required for direct replacement)
• Input voltage rating (10V maximum)
• Protection features (Over Current, Over Temperature, Reverse Polarity)
• Surface Mount mounting type
• RoHS3 compliance

Two substitute parts are identified:

TPS78833DBVT - Parametric equivalent with identical electrical specifications and package format, differing only in tape reel configuration.

TPS76933DBVR - Manufacturer-recommended substitute with reduced output current (100mA) and improved quiescent current performance, suitable for applications where 100mA output is sufficient.

Parameter Comparison

Engineering Selection Recommendations

TPS78833DBVT is the direct parametric equivalent for applications requiring the full 150mA output current specification. Both the main part and this substitute share identical electrical performance and thermal operating range. Selection between TPS78833DBVR and TPS78833DBVT depends on packaging format availability (Cut Tape versus Digi-Reel) and inventory status. Both parts carry Last Time Buy status.

TPS76933DBVR is the manufacturer-recommended substitute for designs where output current requirements do not exceed 100mA. This part offers significant advantages including Active product status (ensuring long-term availability), extended operating temperature range (-40°C ~ 125°C), and substantially lower quiescent current (28 µA versus 385 µA). The reduced dropout voltage (0.2V @ 100mA) provides improved efficiency in current-limited applications. RoHS3 compliance is maintained across all three parts.

Frequently Asked Questions (FAQ)

Q: Can TPS76933DBVR replace TPS78833DBVR in all applications?

A: TPS76933DBVR is suitable only for applications where the maximum required output current does not exceed 100mA. If your circuit requires the full 150mA output capability, TPS76933DBVR is not a direct replacement. For 100mA-limited designs, TPS76933DBVR offers superior performance with lower quiescent current and extended temperature range.

Q: What is the difference between TPS78833DBVR and TPS78833DBVT?

A: These parts are parametrically identical. The difference lies in packaging format: TPS78833DBVR is supplied in Cut Tape, while TPS78833DBVT is also supplied in Cut Tape. Both share the same electrical specifications, thermal characteristics, and Last Time Buy status.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the SOT-23-5 package (SC-74A, SOT-753), ensuring identical pinout and PCB footprint compatibility.

Q: Which substitute should I select for new designs?

A: For new designs, TPS76933DBVR is the preferred choice due to its Active product status, which ensures continued availability and support. If your application requires 150mA output, TPS78833DBVT provides parametric equivalence while maintaining Last Time Buy status.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. TPS78833DBVR, TPS78833DBVT, and TPS76933DBVR are all ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited).
