Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS73201DCQRG4 is determined by strict equivalence across the following critical parameters:

• Identical output configuration (Positive) and output type (Adjustable)
• Matching voltage specifications: Input (Max) 5.5V, Output range 1.2V to 5.5V
• Equivalent current rating: 250mA output
• Identical package type: SOT-223-6
• Matching dropout voltage: 0.15V @ 250mA
• Same operating temperature range: -40°C ~ 125°C
• Identical protection features: Over Current, Over Temperature, Short Circuit, Reverse Polarity
• Same series classification: TPS732xx

The TPS73201DCQR meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The TPS73201DCQR is the direct parametric equivalent for the obsolete TPS73201DCQRG4. Both parts share identical electrical specifications, package configuration, and protection characteristics. The primary distinction is product status: TPS73201DCQRG4 is Obsolete, while TPS73201DCQR maintains Active status with current manufacturing availability.

For new designs and production continuity, TPS73201DCQR is the appropriate selection. Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment. The substitute part is available in Cut Tape (CT) and Digi-Reel packaging options, supporting both prototype and volume production workflows.
