Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5806T-I/KD is determined by strict equivalence across the following critical parameters:

• Functional Equivalence: Hub Controller function with USB 3.1 protocol support
• Interface Compatibility: I2C and SPI interface requirements
• Package Compatibility: 100-VQFN (12x12) with exposed pad configuration
• Electrical Specifications: Supply voltage ranges and operating temperature
• Compliance & Certification: RoHS3 compliance and MSL rating
• Packaging Format: Transition from Tape & Reel (TR) to Cut Tape (CT) & Digi-Reel® format

The USB5806CT-I/KD meets all substitution criteria as an active product from the same manufacturer with identical functional specifications and package geometry.

Parameter Comparison

Engineering Selection Recommendations

The USB5806CT-I/KD is the direct substitute for the obsolete USB5806T-I/KD. Both parts share identical functional specifications, package geometry, and compliance certifications. The primary distinction is product status: USB5806CT-I/KD is active with substantial inventory availability (1,000,399 pcs), whereas USB5806T-I/KD is obsolete with limited stock (910 pcs).

The voltage supply specification for USB5806CT-I/KD (1.08V ~ 1.32V, 3V ~ 3.6V) encompasses the discrete voltage levels specified for USB5806T-I/KD (1.2V, 3.3V), ensuring electrical compatibility within existing circuit designs. Both parts maintain ROHS3 compliance and identical MSL ratings, supporting equivalent handling and storage requirements.

Selection of USB5806CT-I/KD is appropriate for new designs, production continuity, and component replacement applications where the obsolete USB5806T-I/KD is no longer available.

Frequently Asked Questions (FAQ)

Q: Can USB5806CT-I/KD be used as a direct replacement for USB5806T-I/KD in existing designs?

A: Yes. Both parts are functionally equivalent with identical USB 3.1 Hub Controller specifications, I2C/SPI interface support, and 100-VQFN (12x12) package geometry. The voltage supply range of USB5806CT-I/KD encompasses the operating voltages of USB5806T-I/KD.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging?

A: Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® represent different packaging and delivery formats. Both formats contain identical die and package specifications. Selection depends on procurement volume and assembly line requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both USB5806T-I/KD and USB5806CT-I/KD maintain identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 3 (168 Hours) ratings.

Q: Why is USB5806T-I/KD classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The active equivalent USB5806CT-I/KD provides continued access to this functional specification.

Q: Are the operating temperature ranges identical?

A: Yes. Both parts operate across -40°C to 85°C temperature range.
