PI3USB10LP-AZMEX Equivalent & Substitute Parts

Part Overview

The PI3USB10LP-AZMEX is a USB Switch IC manufactured by Diodes Incorporated, designed for dual 2:1 multiplexing applications in USB 2.0 systems. This single-channel USB switch operates with bi-directional capability and is housed in a 10-UQFN surface mount package. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, design updates, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3USB10LP-AZMEX is determined by the following critical parameters:

• Package Compatibility: 10-UQFN surface mount package with compatible pinout
• Channel Configuration: Single-channel USB switch architecture
• Supply Voltage Range: Operating voltage window of 2.7V to 4.4V
• On-State Resistance: Maximum 6.5Ω for signal integrity in USB applications
• Bandwidth Performance: Minimum 1GHz -3dB bandwidth for USB 2.0 compliance
• Bi-Directional Capability: Support for bidirectional signal switching
• Compliance Standards: ROHS3 compliance and USB 2.0 feature set

The NLAS7222BMUTBG from onsemi is identified as a direct substitute based on matching package type (10-UQFN), single-channel configuration, compatible operating temperature range, and equivalent compliance certifications. However, specific electrical parameters differ and must be evaluated for application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the PI3USB10LP-AZMEX and NLAS7222BMUTBG are obsolete products with equivalent compliance certifications (ROHS3, REACH Unaffected, EAR99 classification). Selection between these parts must account for the following electrical parameter differences:

The PI3USB10LP-AZMEX provides superior on-state resistance (6.5Ω versus 12Ω) and higher bandwidth performance (1GHz versus 750MHz), making it preferable for applications requiring minimal signal attenuation and maximum frequency response. The NLAS7222BMUTBG operates within a narrower supply voltage range (3V ~ 3.6V versus 2.7V ~ 4.4V), which may limit applicability in systems with variable power supply specifications.

Both parts maintain identical operating temperature ranges and moisture sensitivity ratings, ensuring thermal and environmental compatibility in equivalent applications. Physical package dimensions differ slightly (1.8x1.4mm versus 1.4x1.8mm), though both conform to the 10-UQFN standard and should accommodate identical PCB footprints.

Frequently Asked Questions (FAQ)

Q: Can the NLAS7222BMUTBG directly replace the PI3USB10LP-AZMEX in all applications?

A: Direct replacement is possible only when the application tolerates the NLAS7222BMUTBG's higher on-state resistance (12Ω), reduced bandwidth (750MHz), and narrower supply voltage range (3V ~ 3.6V). Applications requiring the full 2.7V ~ 4.4V supply range or operating near the 1GHz bandwidth limit require verification against specific circuit requirements.

Q: What is the significance of the different package dimensions (1.8x1.4mm versus 1.4x1.8mm)?

A: Both parts use the 10-UQFN package standard. The dimension notation reflects physical orientation; both occupy equivalent PCB footprint space and are mechanically interchangeable on standard surface mount layouts.

Q: Are there compliance or regulatory differences between these parts?

A: Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected status, and EAR99 ECCN classification. No regulatory barriers exist to substitution from a compliance perspective.

Q: Why is the PI3USB10LP-AZMEX marked as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. Existing inventory may be available through authorized distributors, but long-term availability is not guaranteed. The NLAS7222BMUTBG is also obsolete, requiring evaluation of alternative active products for new designs.

Q: What electrical parameters are most critical for USB 2.0 switch compatibility?

A: On-state resistance directly affects signal integrity and insertion loss. Bandwidth performance determines maximum data rate support. Supply voltage range must encompass the system's power delivery specifications. All three parameters must align with application requirements for successful substitution.
