Substitute Part Grouping Explanation

Substitute parts for the TPS53667RTAR are determined by strict equivalence across the following critical parameters:

• Manufacturer & Series: Texas Instruments D-CAP+™ series
• Functional Topology: 6-phase buck step-down regulator with positive output configuration
• Electrical Specifications: Identical supply voltage range (4.5V ~ 17V), switching frequency range (270kHz ~ 1.1MHz), and control interface (PMBus with current limit and enable features)
• Package & Pinout: 40-WQFN (6x6) with exposed pad for thermal management
• Environmental Compliance: ROHS3 compliant, REACH unaffected, identical moisture sensitivity level (MSL 2, 1 Year)
• Packaging Format: Distinction based on delivery format (bulk vs. tape & reel)

The TPS53667RTAT is a parametric equivalent of the TPS53667RTAR, differing only in packaging format (tape & reel delivery) while maintaining identical electrical performance and physical package specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TPS53667RTAR and TPS53667RTAT are active production parts from Texas Instruments with identical electrical and thermal specifications. Selection between these parts is determined by procurement and assembly requirements rather than functional performance:

• TPS53667RTAR (bulk packaging): Suitable for low-volume prototyping, rework operations, and applications where individual component handling is required.
• TPS53667RTAT (tape & reel packaging): Optimized for high-volume automated assembly processes, reducing handling time and improving production efficiency.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring equivalent reliability and environmental performance across all operating conditions within the specified temperature range (-40°C ~ 150°C).

Frequently Asked Questions (FAQ)

Q: Can TPS53667RTAT be used as a direct replacement for TPS53667RTAR in production?

A: Yes. Both parts are electrically and functionally identical. The only difference is packaging format. TPS53667RTAT uses tape & reel delivery, while TPS53667RTAR uses bulk packaging. Assembly equipment compatibility should be verified based on your production line configuration.

Q: Are there any performance differences between these two part numbers?

A: No. Both parts share identical electrical specifications, including supply voltage range (4.5V ~ 17V), switching frequency capability (270kHz ~ 1.1MHz), phase count (6), and control interface (PMBus). Performance in circuit operation is equivalent.

Q: What is the significance of the packaging format difference?

A: Packaging format affects handling and assembly logistics. Tape & reel (TR) format is designed for automated pick-and-place assembly systems, while bulk format is suitable for manual handling and lower-volume applications. The actual component and its performance remain unchanged.

Q: Are both parts RoHS compliant?

A: Yes. Both TPS53667RTAR and TPS53667RTAT are ROHS3 compliant with identical moisture sensitivity levels (MSL 2, 1 Year rating), ensuring equivalent environmental and regulatory compliance.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. Both parts use the identical 40-WQFN (6x6) package with exposed pad. PCB footprints, thermal management requirements, and electrical connections are identical. No design changes are required when substituting between these part numbers.
