FUSB302B01MPX USB Type-C Controller Equivalent & Substitute Parts

Part Overview

The FUSB302B01MPX is an active USB Type-C controller manufactured by onsemi, designed for USB 2.0 interface applications requiring I2C communication protocol support. This interface controller operates across a supply voltage range of 3.3V to 5V and is housed in a 14-pin MLP package with exposed pad configuration. The part maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating, making it suitable for production deployment in consumer and industrial USB Type-C applications.

Equivalent substitute parts are necessary when primary part availability is constrained, when supply chain optimization requires multiple qualified sources, or when design flexibility permits selection from functionally identical alternatives within the same product family.

Substitute Part Grouping Explanation

Substitution eligibility for the FUSB302B01MPX is determined by strict parametric matching across the following criteria:

Mandatory Matching Parameters:

• Manufacturer: onsemi
• Base Product Number: FUSB302
• Protocol: USB
• Function: Controller
• Interface: I2C
• Standards: USB 2.0
• Voltage Supply: 3.3V, 5V
• Supply Current: 560mA
• Operating Temperature: -40°C to 85°C
• Package Type: 14-WFQFN Exposed Pad
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute parts FUSB302B10MPX and FUSB302B11MPX meet all mandatory parametric requirements and are therefore classified as direct parametric equivalents. Variation in the part number suffix (B01, B10, B11) reflects internal onsemi product line differentiation but does not alter functional or electrical characteristics relevant to circuit design or application performance.

Frequently Asked Questions (FAQ)

Q: Are FUSB302B10MPX and FUSB302B11MPX direct replacements for FUSB302B01MPX?

A: Yes. All three parts share identical electrical specifications, package configuration, and compliance certifications. The suffix variation in the part number does not affect functional performance or circuit compatibility.

Q: Does package designation differ between these parts?

A: No. All three parts use the 14-WFQFN Exposed Pad package with 2.5x2.5mm dimensions. Physical footprint and pin configuration are identical.

Q: Are there any supply voltage or current differences?

A: No. All three parts operate at 3.3V and 5V supply voltages with 560mA supply current specification and identical -40°C to 85°C operating temperature range.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (unlimited) for all variants.

Q: Can these parts be used interchangeably in production?

A: Yes. Parametric equivalence across all specified electrical and mechanical parameters permits direct substitution without circuit redesign or board layout modification.
