Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI5USB8000QZHEX is determined by alignment of the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 16-TQFN (3x3) surface mount package with exposed pad configuration to ensure PCB layout and thermal management compatibility.

Voltage Operating Range: The substitute must operate within or encompass the 4.75V to 5.25V supply voltage specification of the original part.

Automotive Qualification: Both parts must carry AEC-Q100 qualification and automotive grade designation to maintain compliance in automotive applications.

Temperature Range: Operating temperature range of -40°C to 85°C must be supported by the substitute.

RoHS Compliance: ROHS3 compliance status must be maintained for regulatory continuity.

The PI5USB2546QZHEX qualifies as a direct substitute based on these parameters. Both parts share identical package specifications, automotive qualification, temperature operating range, and RoHS compliance status. The substitute maintains the same 16-TQFN (3x3) form factor and thermal characteristics required for direct PCB replacement.
