PI3USB40AE Equivalent & Substitute Parts

Part Overview

The PI3USB40AE 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 compatible 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 obsolete status, sourcing equivalent or substitute components is necessary for production continuity and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3USB40AE is determined by the following critical parameters:

Package Compatibility: The 48-TFSOP (0.240", 6.10mm Width) package is the primary mechanical constraint. Substitute parts must use identical or pin-compatible packaging to ensure PCB layout compatibility without redesign.

Mounting Type: Surface mount technology is required to match the original component's assembly process and footprint.

Regulatory Compliance: RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification must be maintained for supply chain and regulatory continuity.

Moisture Sensitivity Level: MSL 1 (Unlimited) rating ensures no special handling or storage requirements beyond standard component care.

The identified substitute part TS3L301DGG meets these critical parameters while providing enhanced electrical specifications suitable for interface switching applications.

Parameter Comparison

Engineering Selection Recommendations

The TS3L301DGG qualifies as a direct substitute for the PI3USB40AE based on package compatibility, mounting type, and regulatory compliance alignment. Both components share identical package specifications (48-TFSOP), surface mount technology, and regulatory certifications (ROHS3, REACH unaffected, EAR99).

The TS3L301DGG carries a Last Time Buy status, indicating controlled availability. This status provides a defined procurement window for design transitions or inventory planning. The component maintains MSL 1 rating, eliminating special moisture handling requirements.

Selection between these parts should prioritize supply chain availability and project timeline requirements. The TS3L301DGG's enhanced electrical specifications (8 Ohm on-state resistance, 900 MHz bandwidth, 3V–3.6V supply range) position it for applications requiring higher performance characteristics within the interface switching category.

Frequently Asked Questions (FAQ)

Q: Can the TS3L301DGG be used as a direct replacement for the PI3USB40AE without PCB modifications?

A: Yes. Both components use the 48-TFSOP package with identical pin pitch and footprint dimensions (0.240", 6.10mm width). No PCB layout changes are required for mechanical compatibility.

Q: What is the significance of the TS3L301DGG's Last Time Buy status?

A: Last Time Buy indicates the manufacturer has announced end-of-life production. This status establishes a final procurement window. Designs using this substitute should plan for long-term availability or identify secondary alternatives for future production runs.

Q: Are there regulatory or compliance concerns when substituting these parts?

A: No. Both components maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. Regulatory documentation and supply chain requirements remain consistent.

Q: How do the electrical specifications of the TS3L301DGG compare to the PI3USB40AE?

A: The PI3USB40AE electrical specifications are not provided in the component data. The TS3L301DGG specifies 8 Ohm on-state resistance, 3V–3.6V supply voltage, and 900 MHz bandwidth. Functional compatibility should be confirmed through application-specific circuit analysis.

Q: What is the moisture sensitivity implication for both parts?

A: Both components carry MSL 1 (Unlimited) rating. This classification indicates no moisture sensitivity restrictions. Standard component storage and handling practices apply without special environmental controls.

Q: Are there packaging format options for the TS3L301DGG?

A: The TS3L301DGG is supplied in Tube packaging. The PI3USB40AE packaging format is not specified. Confirm packaging requirements for your assembly process and inventory management systems.
