Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB3317-CP-TR is determined by strict alignment of the following electrical and mechanical parameters:

• Protocol Compatibility: USB 2.0 transceiver functionality
• Supply Voltage Range: 1.6V ~ 3.6V
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 24-VFQFN Exposed Pad (4x4mm)
• Mounting Technology: Surface Mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected
• Moisture Sensitivity: MSL 3 (168 Hours)

The USB3317C-CP-TR meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The USB3317C-CP-TR is the direct substitute for the obsolete USB3317-CP-TR. Both components share identical electrical specifications, package geometry, and regulatory compliance certifications. The primary distinction is product status: the USB3317C-CP-TR maintains active production status with current inventory availability, whereas the USB3317-CP-TR is obsolete.

For new designs or ongoing production requiring USB 2.0 transceiver functionality in the 24-VFQFN package, the USB3317C-CP-TR is the appropriate selection. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the USB3317C-CP-TR be used as a direct replacement for the USB3317-CP-TR?

A: Yes. Both parts are manufactured by Microchip Technology and share identical electrical parameters, supply voltage range (1.6V ~ 3.6V), operating temperature range (-40°C ~ 85°C), and package specifications (24-VFQFN Exposed Pad). Pin-to-pin compatibility is maintained.

Q: What is the difference between USB3317-CP-TR and USB3317C-CP-TR?

A: The primary difference is product lifecycle status. The USB3317-CP-TR is obsolete and no longer manufactured. The USB3317C-CP-TR is an active product with current production and inventory availability. All functional and electrical specifications are identical.

Q: Are there any packaging differences between these parts?

A: Both parts use the same 24-VFQFN Exposed Pad (4x4mm) package for surface mount assembly. The USB3317C-CP-TR is available in Cut Tape (CT) and Digi-Reel® packaging options, providing flexibility for different procurement volumes.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the USB3317-CP-TR and USB3317C-CP-TR are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is identical at MSL 3 (168 Hours) for both components.

Q: Which part should be specified for new designs?

A: The USB3317C-CP-TR should be specified for new designs due to its active production status and guaranteed long-term availability. The USB3317-CP-TR, being obsolete, should not be used for new development.
