Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB2660-JZX is determined by the following critical parameters:

• Base Product Number: Both parts share USB2660, confirming functional equivalence within the Microchip Technology product line
• Package / Case: Identical 64-VFQFN Exposed Pad package ensures mechanical and electrical compatibility
• Supplier Device Package: Both use 64-QFN (9x9), guaranteeing PCB footprint compatibility
• Mounting Type: Surface mount compatibility is maintained across both parts
• RoHS Status: Both parts meet ROHS3 compliance requirements
• Moisture Sensitivity Level: Identical MSL 3 (168 Hours) rating ensures equivalent handling and storage requirements

The USB2660I-JZX-03 is identified as a direct substitute based on these matching parameters. The primary distinction is product status: USB2660-JZX is obsolete while USB2660I-JZX-03 is active, making the latter suitable for new designs and ongoing procurement.

Parameter Comparison

Engineering Selection Recommendations

The USB2660I-JZX-03 is the appropriate selection for applications currently using or requiring the USB2660-JZX. This substitution is supported by:

• Identical mechanical compatibility through matching 64-VFQFN Exposed Pad package and 64-QFN (9x9) footprint
• Equivalent electrical specifications and supply voltage requirements
• Active product status ensuring long-term availability and supply chain continuity
• Maintained compliance certifications (ROHS3, REACH Unaffected)
• Consistent moisture sensitivity and handling requirements

The transition from USB2660-JZX (obsolete) to USB2660I-JZX-03 (active) presents no technical barriers for design implementation or PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can USB2660I-JZX-03 be used as a direct replacement for USB2660-JZX?

A: Yes. Both parts share identical package specifications (64-VFQFN Exposed Pad, 64-QFN 9x9), mounting type (surface mount), and compliance ratings. The USB2660I-JZX-03 is the active equivalent of the obsolete USB2660-JZX.

Q: Are there PCB layout modifications required when switching from USB2660-JZX to USB2660I-JZX-03?
