Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the USB7252C/KDX are identified based on strict alignment of the following critical parameters:

Mechanical Compatibility:

• Identical package type: 100-VQFN (12x12) Exposed Pad
• Same supplier device package specification

Electrical Compatibility:

• Matching voltage supply ranges: 1.09V ~ 1.21V and 3V ~ 3.6V
• Identical operating temperature range: 0°C ~ 70°C (TA)

Functional Compatibility:

• Hub Controller function classification
• Identical interface protocol set: GPIO, I2C, I2S, SPI, SMBus, USB
• USB 2.0 standard support (baseline requirement)

Regulatory & Compliance:

• ROHS3 Compliance status
• Moisture Sensitivity Level 3 (168 Hours)
• REACH Unaffected classification
• ECCN EAR99 export control designation

The USB7252C/KDX supports USB 3.2 GEN2 standard. Substitute parts USB7206C/KDX and USB7216C/KDX support USB 3.1 GEN2 standard. Both USB 3.1 GEN2 and USB 3.2 GEN2 specifications maintain backward compatibility with USB 2.0 and share identical electrical, mechanical, and interface characteristics within the scope of this product category.

Parameter Comparison

Engineering Selection Recommendations

All three parts—USB7252C/KDX, USB7206C/KDX, and USB7216C/KDX—are active products from Microchip Technology with identical electrical specifications, mechanical packaging, and interface capabilities. Each part carries ROHS3 compliance certification and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution.

The primary technical distinction between these parts is the USB standard generation supported: USB7252C/KDX implements USB 3.2 GEN2, while USB7206C/KDX and USB7216C/KDX implement USB 3.1 GEN2. Both USB 3.1 GEN2 and USB 3.2 GEN2 specifications maintain full backward compatibility with USB 2.0 and share identical electrical and mechanical characteristics within this product category.

Selection between these parts depends on system-level USB standard requirements. All parts are suitable for applications requiring 100-pin VQFN packaging, dual voltage supply operation, and multi-protocol interface support within the 0°C to 70°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can USB7206C/KDX or USB7216C/KDX be used as direct replacements for USB7252C/KDX?

A: Yes. Both substitute parts share identical electrical specifications, mechanical packaging (100-VQFN 12x12), voltage supply ranges (1.09V ~ 1.21V and 3V ~ 3.6V), operating temperature range (0°C ~ 70°C), and interface protocol support (GPIO, I2C, I2S, SPI, SMBus, USB). The parts differ only in USB standard generation: USB7252C/KDX supports USB 3.2 GEN2, while USB7206C/KDX and USB7216C/KDX support USB 3.1 GEN2. Both generations maintain backward compatibility with USB 2.0.

Q: What are the key parameters that determine substitutability?

A: Substitutability is determined by: package type (100-VQFN 12x12 Exposed Pad), voltage supply ranges (1.09V ~ 1.21V and 3V ~ 3.6V), operating temperature (0°C ~ 70°C), interface protocol set (GPIO, I2C, I2S, SPI, SMBus, USB), USB 2.0 baseline support, RoHS3 compliance, and Moisture Sensitivity Level 3 (168 Hours).

Q: Are there differences in compliance certifications between these parts?

A: No. All three parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, ECCN EAR99, and Moisture Sensitivity Level 3 (168 Hours).

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

A: USB 3.2 GEN2 and USB 3.1 GEN2 are different USB standard generations. Both maintain backward compatibility with USB 2.0 and share identical electrical and mechanical specifications within this product category. Selection depends on system-level USB standard requirements.

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

A: Yes. All three parts use the same 100-VQFN (12x12) Exposed Pad package with identical pin configurations and electrical specifications. No PCB redesign is required for substitution.

Q: What is the Moisture Sensitivity Level (MSL) and why does it matter?

A: Moisture Sensitivity Level 3 (168 Hours) indicates the component can be exposed to ambient conditions (23°C, 50% relative humidity) for up to 168 hours before soldering without requiring baking. This specification affects component storage and handling procedures.

Q: Are all three parts currently available?

A: Yes. USB7252C/KDX has 1,138 units in stock, USB7206C/KDX has 762 units in stock, and USB7216C/KDX has 1,398 units in stock.
