PI3USB40AEX Equivalent & Substitute Parts

Part Overview

The PI3USB40AEX is an octal USB switch IC manufactured by Diodes Incorporated, housed in a 48-TSSOP package. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations. The part functions as a 2:1 multiplexer/demultiplexer switch circuit suitable for USB signal routing applications. Due to its discontinued status, sourcing equivalent components with compatible electrical and mechanical characteristics is necessary for production continuity and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3USB40AEX is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 48-TFSOP (0.240", 6.10mm Width) package in 48-TSSOP configuration to ensure PCB layout compatibility without redesign.
• Mounting Type: Surface mount technology must be maintained for manufacturing process consistency.
• Regulatory Compliance: RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification must be preserved for supply chain and export requirements.
• Moisture Sensitivity: MSL 1 (Unlimited) rating ensures no special handling requirements during storage and assembly.

The TS3L301DGGR from Texas Instruments meets all mandatory package, mounting, and compliance criteria, qualifying it as a direct substitute for the obsolete PI3USB40AEX.

Parameter Comparison

Engineering Selection Recommendations

The TS3L301DGGR is qualified as a direct substitute for the PI3USB40AEX based on the following factors:

• Package Equivalence: Identical 48-TFSOP package dimensions and pin configuration eliminate PCB layout modifications.
• Active Product Status: The TS3L301DGGR maintains active manufacturing status, ensuring long-term availability and supply chain stability compared to the obsolete PI3USB40AEX.
• Regulatory Alignment: Both components maintain ROHS3 compliance, REACH unaffected designation, and EAR99 ECCN classification, satisfying regulatory requirements without additional qualification.
• Moisture Handling: Matching MSL 1 rating confirms compatibility with standard assembly and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can the TS3L301DGGR be used as a direct replacement for the PI3USB40AEX without PCB modifications?

A: Yes. Both components use the identical 48-TFSOP package with 0.240" width and 48-TSSOP pin configuration, enabling direct substitution without PCB layout changes.

Q: What is the primary reason for substituting the PI3USB40AEX?

A: The PI3USB40AEX is classified as obsolete. The TS3L301DGGR, with active product status, provides a compliant alternative for new designs and production continuity.

Q: Are there any compliance concerns when switching from PI3USB40AEX to TS3L301DGGR?
