Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3USB221ZEEX is determined by strict equivalence across the following critical parameters:

• Base product number (PI3USB221 series)
• Single-channel configuration with 2:1 multiplexer/demultiplexer circuit
• On-state resistance maximum of 6 Ohm
• Supply voltage range of 2.3V ~ 3.6V
• -3dB bandwidth of 1.1 GHz
• Bi-directional USB 2.0 switching capability
• Operating temperature range of -40°C ~ 85°C
• Surface mount package with exposed pad
• ROHS3 compliance and MSL Level 1 rating

The PI3USB221AZWEX qualifies as a direct substitute based on identical electrical specifications and functional characteristics. The primary distinction lies in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The PI3USB221AZWEX is the designated manufacturer-recommended substitute for the obsolete PI3USB221ZEEX. Both components maintain identical electrical and functional specifications, ensuring direct compatibility in USB 2.0 switching applications.

Selection of the PI3USB221AZWEX provides the following advantages:

• Active product status with ongoing manufacturer support
• Identical electrical performance and switching characteristics
• Full compliance with ROHS3 and REACH requirements
• MSL Level 1 rating suitable for unlimited shelf life storage
• Availability in Tape & Reel packaging for production environments

The package designation difference (10-VFDFN versus 10-UFDFN) reflects manufacturing process variations within the same physical footprint and pin configuration, maintaining full PCB layout compatibility.

Frequently Asked Questions (FAQ)
