TPS53015DGS Equivalent & Substitute Parts

Part Overview

The TPS53015DGS is a buck regulator positive output step-down DC-DC controller IC manufactured by Texas Instruments in a 10-VSSOP package. This device functions as a transistor driver for single-output, single-phase buck topology applications with a supply voltage range of 4.5V to 28V and a switching frequency of 500kHz. The TPS53015DGS is currently in Last Time Buy status, making identification of equivalent substitute parts essential for design continuity and procurement planning. The TPS53015DGSR provides a direct functional equivalent with improved availability and active product status.

Substitute Part Grouping Explanation

The TPS53015DGSR qualifies as a direct substitute for the TPS53015DGS based on identical electrical and mechanical parameters. Both parts share the same base product number (TPS53015), identical functional specifications, and compatible package designations. The substitution is valid across the following critical parameters:

• Voltage supply range: 4.5V ~ 28V (identical)
• Switching frequency: 500kHz (identical)
• Output configuration: Single-output, single-phase buck topology (identical)
• Control features: Enable and Power Good functions (identical)
• Operating temperature range: -40°C ~ 85°C (identical)
• Package / Case: 10-TFSOP, 10-MSOP (0.118", 3.00mm Width) (identical)
• Synchronous rectifier capability: Yes (identical)
• Series technology: D-CAP2™, Eco-Mode™ (identical)
• Compliance certifications: ROHS3, REACH Unaffected (identical)

The primary distinction between these parts is packaging format (Tube versus Cut Tape & Digi-Reel®) and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TPS53015DGSR is the recommended substitute for the TPS53015DGS. This recommendation is based on the following factors:

• Electrical equivalence: All functional parameters, electrical specifications, and control features are identical between the two parts.
• Mechanical compatibility: Both parts utilize the same 10-VSSOP package with identical pin configurations and physical dimensions.
• Compliance alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory continuity.
• Product lifecycle: The TPS53015DGSR maintains Active product status, providing long-term availability and support, whereas the TPS53015DGS is in Last Time Buy status.
• Inventory availability: The TPS53015DGSR demonstrates significantly higher inventory levels (5200 Pcs versus 784 Pcs), supporting procurement reliability.

For new designs or design revisions, the TPS53015DGSR should be specified. For existing designs currently using the TPS53015DGS, substitution with the TPS53015DGSR is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Are the TPS53015DGS and TPS53015DGSR pin-compatible?

A: Yes. Both parts use the 10-VSSOP package with identical pin assignments and electrical characteristics. No PCB layout modifications are required for substitution.

Q: What is the difference between Tube and Cut Tape & Digi-Reel® packaging?

A: Tube packaging is used for lower-volume orders and manual handling, while Cut Tape & Digi-Reel® packaging is optimized for automated assembly processes and higher-volume production. The electrical and functional performance of the component is identical regardless of packaging format.

Q: Can I use the TPS53015DGSR in a design currently specified for the TPS53015DGS?

A: Yes. The TPS53015DGSR is a direct functional and mechanical equivalent. No circuit design changes, PCB modifications, or firmware updates are required.

Q: Why is the TPS53015DGS marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific part number variant. The TPS53015DGSR remains in Active status and is the recommended long-term alternative.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts operate within the same temperature range (-40°C ~ 85°C) and deliver identical switching frequency (500kHz), control features, and efficiency characteristics.

Q: What compliance certifications apply to both parts?

A: Both the TPS53015DGS and TPS53015DGSR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
