Substitute Part Grouping Explanation

Substitution eligibility for the PI3CH3257LEX is determined by strict alignment of the following parameters:

• Circuit configuration: 4 x 2:1 multiplexer/demultiplexer topology
• Voltage supply range: 2.97V ~ 3.63V single supply operation
• Operating temperature range: -40°C ~ 85°C
• Package type: 16-TSSOP with 0.173" width (4.40mm)
• Surface mount mounting type
• Logic category classification
• RoHS3 and REACH compliance status

The PI3B3257LEX-2017 meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, package dimensions, and compliance certifications, enabling direct substitution in circuit designs.
