Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USB7252CT/KDX are identified based on strict alignment of the following critical parameters:

Electrical Compatibility Criteria:

• Voltage supply range: 1.09V ~ 1.21V and 3V ~ 3.6V
• Operating temperature range: 0°C ~ 70°C (TA)
• Protocol support: USB with GPIO, I2C, I2S, SPI, and SMBus interfaces

Mechanical Compatibility Criteria:

• Package type: 100-VQFN (12x12) with exposed pad
• Moisture sensitivity level: 3 (168 Hours)

Regulatory & Compliance Criteria:

• RoHS3 compliance
• REACH unaffected status
• ECCN: EAR99 classification

Functional Criteria:

• Hub controller function
• USB 2.0 support (mandatory)
• Manufacturer: Microchip Technology
• Product status: Active

The USB7206CT/KDX and USB7216CT/KDX meet all electrical, mechanical, and regulatory requirements for substitution. The primary distinction between these parts is the USB generation support (USB 3.1 GEN2 versus USB 3.2 GEN2) and packaging format (Cut Tape & Digi-Reel® or Cut Tape versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

USB7252CT/KDX (Primary Part): The USB7252CT/KDX is the primary specification with USB 3.2 GEN2 capability and Tape & Reel packaging. This part is suitable for high-volume production environments where reel-based component handling is standard. Active product status and full ROHS3 compliance ensure long-term availability and regulatory adherence.

USB7206CT/KDX (Substitute - Preferred Alternative): The USB7206CT/KDX provides functional equivalence with USB 3.1 GEN2 support and Cut Tape & Digi-Reel® packaging. This part maintains all electrical specifications, interface protocols, and compliance certifications. The alternative packaging format accommodates different procurement and assembly workflows. Active product status confirms ongoing manufacturing support.

USB7216CT/KDX (Substitute - Alternative): The USB7216CT/KDX offers functional equivalence with USB 3.1 GEN2 support and Cut Tape packaging. This part maintains all electrical specifications, interface protocols, and compliance certifications. The Cut Tape format is suitable for lower-volume or mixed-component assembly processes. Active product status confirms ongoing manufacturing support.

All three parts share identical electrical operating parameters, thermal specifications, and regulatory compliance status. Selection between these parts is determined by packaging format requirements and USB generation specifications appropriate to the application.

Frequently Asked Questions (FAQ)

Q: Can USB7206CT/KDX or USB7216CT/KDX be used as direct replacements for USB7252CT/KDX?

A: Yes. Both substitute parts maintain identical electrical specifications including voltage supply range (1.09V ~ 1.21V, 3V ~ 3.6V), operating temperature range (0°C ~ 70°C), and all supported interface protocols (GPIO, I2C, I2S, SPI, SMBus, USB). The primary differences are USB generation support (USB 3.1 versus USB 3.2) and packaging format (Cut Tape variants versus Tape & Reel).

Q: What is the difference between USB 3.2 GEN2 and USB 3.1 GEN2 support?

A: USB 3.2 GEN2 and USB 3.1 GEN2 represent different USB specification generations. The USB7252CT/KDX implements USB 3.2 GEN2, while USB7206CT/KDX and USB7216CT/KDX implement USB 3.1 GEN2. Both support USB 2.0 as a baseline standard. The selection between these generations depends on application requirements for data transfer rates and protocol features.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The USB7252CT/KDX is supplied in Tape & Reel (TR) format, suitable for automated reel-fed assembly equipment. The USB7206CT/KDX is supplied in Cut Tape (CT) & Digi-Reel® format, and the USB7216CT/KDX is supplied in Cut Tape (CT) format. These packaging differences affect component handling, storage, and assembly processes. Verify that your assembly equipment and procurement workflow accommodate the selected packaging format.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is identical at 3 (168 Hours) for all parts. These compliance certifications ensure regulatory adherence across all three options.

Q: What is the significance of the 100-VQFN (12x12) package?

A: The 100-VQFN (12x12) package is a 100-pin Very Thin Quad Flat No-Lead package with 12mm x 12mm dimensions and an exposed pad for thermal management. All three substitute parts use this identical package type, ensuring mechanical and thermal compatibility in PCB layouts and thermal design considerations.

Q: Are there inventory or lead-time differences between these parts?

A: Inventory levels vary. The USB7252CT/KDX has 3,199 pieces in stock, USB7206CT/KDX has 1,000,299 pieces in stock, and USB7216CT/KDX has 1,000,099 pieces in stock. These inventory levels may affect procurement timelines and should be considered in supply chain planning.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on application-specific requirements for USB generation support and packaging format. If the design requires USB 3.2 GEN2 specifically, only the USB7252CT/KDX is appropriate. If USB 3.1 GEN2 meets application requirements, either USB7206CT/KDX or USB7216CT/KDX can be used. Packaging format must align with assembly equipment capabilities.
