Substitute Part Grouping Explanation

Substitution of the TPS73201DCQ is determined by strict equivalence across the following critical parameters:

• Identical package type: SOT-223-6 surface mount
• Matching output configuration: Positive adjustable
• Equivalent electrical specifications: 250mA output current, 5.5V maximum input, 1.2V to 5.5V adjustable output range
• Identical voltage dropout performance: 0.15V @ 250mA
• Same control and protection features: Enable control, Over Current, Over Temperature, Short Circuit, and Reverse Polarity protection
• Matching operating temperature range: -40°C ~ 125°C
• Compliance with RoHS3 and REACH requirements

The TPS73201DCQR qualifies as a direct substitute based on full alignment with all specified parameters.

Parameter Comparison

Engineering Selection Recommendations

The TPS73201DCQR is the direct substitute for the TPS73201DCQ. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the TPS73201DCQ is Last Time Buy, while the TPS73201DCQR maintains Active status, ensuring continued availability and long-term supply chain support.

Both parts meet ROHS3 compliance and REACH requirements, making them suitable for applications requiring regulatory adherence. The TPS73201DCQR is recommended for new designs and production continuity due to its active product status and availability in standard distribution channels.

Frequently Asked Questions (FAQ)

Q: Can TPS73201DCQR replace TPS73201DCQ in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. No circuit modifications are required for substitution.

Q: What is the difference between the tube and cut tape packaging options?

A: The TPS73201DCQ is supplied in tube packaging, while the TPS73201DCQR is available in cut tape and Digi-Reel formats. All three packaging options contain the same die and electrical performance. Packaging selection depends on assembly process requirements and volume needs.

Q: Why is the TPS73201DCQ marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer has discontinued active production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. The TPS73201DCQR, with Active status, is the recommended path forward for sustained supply.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain identical RoHS3 and REACH compliance status, with matching Moisture Sensitivity Level (MSL) ratings of 2 (1 Year).

Q: Can these parts be used interchangeably on the same PCB assembly line?

A: Yes. Identical SOT-223-6 package specifications and pinout allow direct substitution without PCB layout modifications. Assembly process parameters remain unchanged.
