Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5826T/KD is determined by the following critical parameters:

• Package Compatibility: Identical 100-VQFN (12x12) form factor with exposed pad
• Functional Classification: USB Hub Controller designation
• Protocol Support: USB standard compliance (USB 2.0 and/or USB 3.1)
• Interface Protocols: I2C, SPI, and related communication interfaces
• Voltage Supply Range: Compatible operating voltage specifications
• Operating Temperature Range: 0°C ~ 70°C
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected status
• Moisture Sensitivity: MSL 3 (168 Hours)

The USB5826CT/KD qualifies as a direct substitute based on these parameters. It maintains identical packaging, form factor, and temperature specifications while supporting expanded interface protocols (addition of SMBus and UART) and dual USB standard support (USB 2.0 and USB 3.1).

Parameter Comparison

Engineering Selection Recommendations

The USB5826CT/KD is the qualified substitute for the obsolete USB5826T/KD based on the following engineering criteria:

• Product Status Alignment: The substitute maintains Active product status, ensuring long-term availability and manufacturing support compared to the Obsolete status of the main part.
• Regulatory Compliance: Both parts maintain ROHS3 Compliant and REACH Unaffected certifications, satisfying environmental and regulatory requirements.
• Identical Physical Interface: The 100-VQFN (12x12) package with exposed pad ensures direct mechanical and electrical compatibility without PCB redesign.
• Expanded Functional Capability: The substitute supports additional interface protocols (SMBus, UART) and dual USB standards (USB 2.0 and USB 3.1), providing enhanced flexibility for system integration.
• Voltage Supply Compatibility: The substitute's voltage range (1.08V ~ 1.32V, 3V ~ 3.6V) encompasses the main part's specifications (1.2V, 3.3V), ensuring operational compatibility.
• Thermal Specifications: Identical operating temperature range (0°C ~ 70°C) maintains thermal design consistency.

Frequently Asked Questions (FAQ)

Q: Can the USB5826CT/KD directly replace the USB5826T/KD without PCB modifications?

A: Yes. Both parts use the 100-VQFN (12x12) package with exposed pad, identical pin count, and compatible electrical specifications. No PCB layout changes are required for physical substitution.

Q: What are the key differences between these parts?

A: The USB5826CT/KD is an active product with expanded interface support (SMBus and UART protocols) and dual USB standard capability (USB 2.0 and USB 3.1), compared to the USB5826T/KD which supports only I2C and SPI interfaces with USB 3.1. The substitute also features a refined voltage supply range specification.

Q: Are there compliance or certification differences?

A: No. Both parts maintain identical ROHS3 Compliant and REACH Unaffected certifications, with matching Moisture Sensitivity Level 3 (168 Hours) ratings.

Q: Why is the USB5826T/KD marked as Obsolete?

A: The Obsolete status indicates the part is no longer in active production. The USB5826CT/KD represents the current active alternative from Microchip Technology for this hub controller function.

Q: What packaging options are available for the substitute?

A: The USB5826CT/KD is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Are the voltage supply specifications compatible?

A: Yes. The substitute's voltage range (1.08V ~ 1.32V for 1.2V rail, 3V ~ 3.6V for 3.3V rail) fully encompasses the main part's specifications and maintains operational compatibility across all supply conditions.
