Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB3316B-CP-TR is determined by strict alignment of the following critical parameters:

• Manufacturer & Series: Microchip Technology flexPWR™ series ensures design continuity and pin compatibility
• Protocol & Function: USB 2.0 transceiver classification maintains functional equivalence
• Package Type: 24-VFQFN Exposed Pad ensures mechanical and electrical compatibility with existing PCB layouts
• Supply Voltage Range: 1.62V ~ 1.98V defines the operating envelope for power delivery circuits
• Operating Temperature Range: -40°C ~ 85°C establishes thermal compatibility with system requirements
• Compliance Standards: ROHS3 compliance and identical MSL ratings ensure regulatory and manufacturing process compatibility

The USB3316C-CP-TR qualifies as a direct substitute based on complete alignment across all these parameters. The primary distinction is product status: USB3316C-CP-TR is Active, whereas USB3316B-CP-TR is Obsolete.

Parameter Comparison

Engineering Selection Recommendations

The USB3316C-CP-TR is the direct substitute for USB3316B-CP-TR. Selection of the active part is justified by:

• Product Status: USB3316C-CP-TR maintains Active status, ensuring continued manufacturer support, availability, and compliance updates
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH Unaffected status, satisfying current environmental and safety requirements
• Functional Equivalence: Complete parameter alignment across voltage, temperature, package, and protocol specifications ensures drop-in compatibility
• Supply Chain Continuity: Transition to the active variant eliminates obsolescence risk and supports long-term production requirements

Frequently Asked Questions (FAQ)

Q: Can USB3316C-CP-TR be used as a direct replacement for USB3316B-CP-TR?

A: Yes. The USB3316C-CP-TR is a direct substitute. Both parts share identical electrical specifications, package geometry, supply voltage range, operating temperature range, and compliance certifications. The primary difference is product status: USB3316C-CP-TR is Active while USB3316B-CP-TR is Obsolete.

Q: Are there any pin compatibility concerns between these parts?

A: No. Both parts use the 24-VFQFN Exposed Pad package with identical pinout and electrical characteristics. PCB layouts and schematics require no modification.

Q: What is the significance of the product status difference?

A: Product status indicates manufacturer support lifecycle. Active parts receive ongoing support, compliance updates, and guaranteed availability. Obsolete parts are no longer manufactured and may face supply constraints. Transitioning to USB3316C-CP-TR ensures long-term design viability.

Q: Do the parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 3 (168 Hours) rating, requiring identical handling, storage, and reflow procedures.

Q: Are there packaging differences between these parts?

A: The primary packaging difference is that USB3316C-CP-TR is specified as Tape & Reel (TR), while USB3316B-CP-TR packaging is not specified. Both use the same 24-VFQFN Exposed Pad case. Tape & Reel packaging is standard for high-volume production and does not affect component functionality or compatibility.
