Key Parameters

Substitute Part Grouping Explanation

Substitution of the REF5045AIDGKT is determined by strict equivalence across the following critical parameters:

• Output voltage specification: 4.5V fixed
• Tolerance class: ±0.1%
• Output current capability: 10 mA
• Temperature coefficient: 8 ppm/°C
• Input voltage operating range: 4.7V ~ 18V
• Package type: 8-VSSOP (8-TSSOP, 8-MSOP)
• Mounting configuration: Surface Mount
• Manufacturer: Texas Instruments
• Base product number: REF5045

The REF5045AIDGKR qualifies as a parametric equivalent because it maintains identical electrical specifications and mechanical compatibility. The only distinction between these parts is the packaging format: the main part uses Tape & Reel (TR) packaging, while the substitute uses Cut Tape (CT) & Digi-Reel® packaging. Both packaging formats contain the identical die and are suitable for automated assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Both the REF5045AIDGKT and REF5045AIDGKR are active production components from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

The REF5045AIDGKT in Tape & Reel packaging is suitable for high-volume automated assembly operations where continuous reel feeding is required. The REF5045AIDGKR in Cut Tape & Digi-Reel® packaging accommodates lower-volume production runs, prototype builds, and applications where partial reel quantities are needed.

Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring equivalent environmental and regulatory performance. The choice between these variants does not affect circuit performance, reliability, or long-term operational characteristics.

Frequently Asked Questions (FAQ)

Q: Can REF5045AIDGKR be used as a direct replacement for REF5045AIDGKT in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format. If your assembly process can accommodate Cut Tape & Digi-Reel® packaging, the REF5045AIDGKR is a direct substitute.

Q: Are there any performance differences between Tape & Reel and Cut Tape packaging?

A: No. The internal die, electrical characteristics, and performance specifications are identical. Packaging format affects only procurement logistics and assembly handling, not circuit behavior.

Q: What does the packaging designation mean?

A: Tape & Reel (TR) packaging supplies components on continuous reels for automated high-speed pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components in tape segments on smaller reels, suitable for lower-volume or mixed-component assembly.

Q: Are both parts RoHS compliant?

A: Yes. Both REF5045AIDGKT and REF5045AIDGKR are ROHS3 compliant and carry identical environmental certifications.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical, they can be used interchangeably within the same circuit design and production run without any functional impact.
