USB7206/KDX Equivalent & Substitute Parts

Part Overview

The USB7206/KDX is a USB Hub Controller manufactured by Microchip Technology, designed for USB 3.1 GEN2 applications without Power Delivery or Type-C support. This component operates as an interface controller with I2C and SPI communication protocols, housed in a 100-VQFN (12x12) package with exposed pad.

The USB7206/KDX is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this controller architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB7206/KDX is determined by the following critical parameters:

Package Compatibility: The substitute part must utilize the same 100-VFQFN Exposed Pad package (100-VQFN 12x12 footprint) to ensure mechanical and thermal compatibility with existing PCB designs.

Functional Compatibility: The substitute must operate as a USB Hub Controller with support for USB protocol communication and I2C/SPI interface capabilities.

Electrical Specifications: The substitute must operate within the voltage supply range of 1.09V ~ 3.6V and maintain the same operating temperature range of 0°C ~ 70°C.

Compliance Requirements: The substitute must maintain ROHS3 compliance, REACH unaffected status, and equivalent moisture sensitivity level (MSL 3, 168 Hours).

Manufacturer Continuity: Substitutes are sourced from Microchip Technology to ensure design consistency and technical support alignment.

The USB7206C/KDX qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: USB7206C/KDX

The USB7206C/KDX is the direct substitute for the obsolete USB7206/KDX. Both components share identical package specifications (100-VQFN 12x12), operating temperature range (0°C ~ 70°C), and compliance certifications (ROHS3, REACH Unaffected, MSL 3).

The USB7206C/KDX maintains backward compatibility with the original design while offering active product status from Microchip Technology. This ensures continued technical support, availability, and supply chain reliability.

The substitute part expands interface capabilities to include GPIO, I2S, and SMBus protocols, and adds USB 2.0 support alongside USB 3.1. These enhancements do not conflict with existing designs and provide additional functionality for future development iterations.

Voltage supply specifications are compatible within the operational envelope of the original part. The USB7206C/KDX operates at 1.09V ~ 1.21V and 3V ~ 3.6V, which encompasses the original 1.09V ~ 3.6V range.

Frequently Asked Questions (FAQ)

Q: Can the USB7206C/KDX be used as a direct replacement for the USB7206/KDX in existing designs?

A: Yes. Both parts utilize the 100-VQFN (12x12) package with identical pinout and footprint. Operating temperature ranges, voltage specifications, and compliance certifications are compatible. No PCB redesign is required.

Q: What is the primary difference between USB7206/KDX and USB7206C/KDX?

A: The USB7206C/KDX is the active production variant of the USB7206/KDX. The substitute part adds GPIO, I2S, and SMBus interface support, and includes USB 2.0 compatibility alongside USB 3.1. The original part is classified as obsolete.

Q: Are there any voltage supply incompatibilities between the two parts?

A: No. The USB7206C/KDX voltage supply range (1.09V ~ 1.21V, 3V ~ 3.6V) is compatible with the original part specification (1.09V ~ 3.6V). Both parts operate within the same electrical envelope.

Q: Do both parts meet the same compliance and regulatory requirements?

A: Yes. Both the USB7206/KDX and USB7206C/KDX are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 3, 168 Hours). Regulatory and environmental compliance is equivalent.

Q: What packaging format is available for the USB7206C/KDX?

A: The USB7206C/KDX is supplied in Tray packaging. The original USB7206/KDX packaging format is not specified in the provided data.

Q: Can the additional interfaces on the USB7206C/KDX cause compatibility issues?

A: No. The expanded interface set (GPIO, I2S, SMBus) on the USB7206C/KDX is additive and does not conflict with the original I2C and SPI interface requirements. Existing designs utilizing I2C and SPI communication remain fully compatible.
