Substitute Part Grouping Explanation

The TPS53014DGSR qualifies as a direct substitute for the TPS53014DGS based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria:

Key Parameters Determining Substitution:

• Identical output topology (buck, single-phase, positive output)
• Matching voltage supply range (4.5V ~ 28V)
• Same switching frequency (500kHz)
• Equivalent control architecture (enable, soft start)
• Identical package specification (10-VSSOP)
• Matching operating temperature range (-40°C ~ 85°C)
• Equivalent synchronous rectifier implementation
• Identical series designation (D-CAP2™, Eco-Mode™)

The sole distinction between these parts is packaging format: TPS53014DGS is supplied in Tube packaging, while TPS53014DGSR is supplied in Tape & Reel (TR) format. This difference affects only logistics and handling, not electrical or mechanical compatibility. Additionally, TPS53014DGSR maintains Active product status, ensuring continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The TPS53014DGSR is the qualified substitute for TPS53014DGS applications. Selection between these parts should be based on the following criteria:

Use TPS53014DGS when:

• Existing inventory or design documentation specifies tube packaging
• Current supply chain logistics accommodate tube format handling

Use TPS53014DGSR when:

• New designs or redesigns are being implemented
• Automated assembly processes require tape & reel packaging
• Long-term supply continuity is required (Active product status)
• Volume production demands standardized packaging formats

Both parts maintain identical electrical performance, thermal characteristics, and regulatory compliance (ROHS3, REACH Unaffected). The TPS53014DGSR is recommended for new designs due to its Active product status, ensuring manufacturer support and continued availability throughout the product lifecycle.

Frequently Asked Questions (FAQ)

Q: Can TPS53014DGSR be used as a direct replacement for TPS53014DGS in existing designs?

A: Yes. All electrical specifications, control features, package dimensions, and thermal characteristics are identical. The only difference is packaging format (tube versus tape & reel). No circuit modifications or PCB redesign is required.

Q: What is the significance of the different packaging formats?

A: Tube packaging (TPS53014DGS) is suitable for manual handling and lower-volume applications. Tape & Reel packaging (TPS53014DGSR) is optimized for automated pick-and-place assembly and high-volume production. Both formats contain the same die and provide identical electrical performance.

Q: Why is TPS53014DGS marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments is discontinuing this specific packaging configuration. The TPS53014DGSR in tape & reel format remains in Active status and is the recommended path forward for continued supply.

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

A: No. Both parts operate within the same temperature range (-40°C ~ 85°C), maintain identical moisture sensitivity levels (MSL 2), and share the same D-CAP2™ and Eco-Mode™ series characteristics.

Q: Can these parts be mixed in the same production batch?

A: Yes, from an electrical standpoint. However, logistics and assembly processes may require standardization on a single packaging format. Consult your manufacturing and procurement teams regarding packaging consolidation strategies.

Q: What compliance certifications apply to both parts?

A: Both TPS53014DGS and TPS53014DGSR are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.
