TPS54527DDA Equivalent & Substitute Parts

Part Overview

The TPS54527DDA is a buck switching regulator IC from Texas Instruments, part of the D-CAP2™ series. It functions as a step-down converter with positive adjustable output, delivering up to 5A at switching frequency of 650kHz. The device operates across input voltage range of 4.5V to 18V with adjustable output from 0.76V to 6V, incorporating synchronous rectification for improved efficiency. This Active product is ROHS3 compliant and suitable for surface mount applications in 8-PowerSOIC packaging. Substitute parts are identified when packaging format differs while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the TPS54527DDA is determined by strict equivalence across all electrical and mechanical parameters. The primary substitution criterion is packaging format. The TPS54527DDA is supplied in Bulk packaging, while the TPS54527DDAR is supplied in Cut Tape (CT) & Digi-Reel® packaging. Both variants share identical:

• Manufacturer: Texas Instruments
• Base Product Number: TPS54527
• Electrical specifications (input/output voltage, current rating, switching frequency)
• Synchronous rectification capability
• Package type: 8-PowerSOIC (0.154", 3.90mm Width)
• Thermal and compliance ratings

The substitution is valid because packaging format does not affect electrical performance or mechanical compatibility in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both TPS54527DDA and TPS54527DDAR are Active products from Texas Instruments with identical electrical and mechanical specifications. Selection between these variants depends on procurement and assembly requirements:

The TPS54527DDA in Bulk packaging is suitable for high-volume manufacturing environments with automated tape-and-reel handling systems or when bulk quantities are preferred for inventory management.

The TPS54527DDAR in Cut Tape & Digi-Reel® packaging is suitable for applications requiring standard reel formats compatible with pick-and-place equipment or when smaller quantity orders are necessary.

Both variants maintain ROHS3 compliance, REACH Unaffected status, and identical thermal performance across the -40°C to 85°C operating range. No electrical performance difference exists between the two packaging formats.

Frequently Asked Questions (FAQ)

Q: Can TPS54527DDAR replace TPS54527DDA in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Bulk versus Cut Tape & Digi-Reel®). Substitution is valid for any application using the 8-PowerSOIC package.

Q: Does packaging format affect circuit performance?

A: No. Packaging format is a supply chain and assembly consideration only. Electrical specifications, thermal performance, and switching characteristics are identical between both variants.

Q: Are there any compliance differences between these parts?

A: No. Both TPS54527DDA and TPS54527DDAR share identical RoHS3 compliance, REACH status, ECCN classification, and HTSUS codes.

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

A: Bulk packaging supplies loose components, while Cut Tape & Digi-Reel® packaging provides components on standard carrier tape wound on reels. Both formats contain the same die and package type (8-PowerSOIC).

Q: Can I use TPS54527DDAR if my design specifies TPS54527DDA?

A: Yes, provided your assembly process supports Cut Tape & Digi-Reel® format. The electrical and mechanical compatibility is complete.
