Substitute Part Grouping Explanation

Substitution eligibility for the USB7252C-I/KDX is determined by the following critical parameters:

Mechanical Compatibility: Package type must be 100-VQFN (12x12) with exposed pad configuration to ensure PCB footprint compatibility without layout redesign.

Electrical Specifications: Supply voltage ranges (1.09V – 1.21V and 3V – 3.6V) and operating temperature range (-40°C to 85°C) must be maintained to preserve circuit functionality and thermal performance.

Functional Interface: The substitute must support the same communication protocols: GPIO, I2C, I2S, SPI, SMBus, and USB interfaces.

Compliance Standards: RoHS3 compliance, REACH unaffected status, and MSL 3 rating must be equivalent to ensure regulatory and environmental requirements are met.

USB Protocol Support: While the main part supports USB 3.2 Gen 2, substitute parts supporting USB 3.1 Gen 2 or USB 3.2 Gen 2 are functionally compatible due to backward compatibility and overlapping electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the USB7252C-I/KDX and USB7206C-I/KDX are active production components from Microchip Technology with identical electrical specifications, packaging, and compliance certifications. Selection between these parts is based on application-specific USB protocol requirements and inventory availability.

The USB7252C-I/KDX supports USB 3.2 Gen 2 protocol and is suitable for applications requiring the latest USB 3.2 specification. The USB7206C-I/KDX supports USB 3.1 Gen 2 protocol and is appropriate for designs compatible with USB 3.1 specifications. Both devices maintain identical supply voltage ranges, operating temperature specifications, and interface capabilities.

From a compliance perspective, both parts satisfy ROHS3 requirements, maintain REACH unaffected status, and carry equivalent MSL 3 moisture sensitivity ratings. PCB integration is identical due to matching 100-VQFN (12x12) package configurations with exposed pads.

Inventory considerations show the USB7206C-I/KDX with higher stock availability (2200 units) compared to the USB7252C-I/KDX (920 units), which may influence procurement decisions for high-volume production schedules.

Frequently Asked Questions (FAQ)

Q: Can the USB7206C-I/KDX replace the USB7252C-I/KDX in existing designs?

A: Yes, the USB7206C-I/KDX is a direct substitute for the USB7252C-I/KDX.
