Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI7C9X760BZDEX is determined by the following critical parameters:

• Base Product Number: Both parts must share the PI7C9X760 base designation, indicating identical core functionality and pinout
• Package / Case: Both parts must use 24-VFQFN Exposed Pad package to ensure mechanical and electrical compatibility
• Supplier Device Package: Both parts must be 24-TQFN (4x4) format for PCB footprint compatibility
• Function: Both parts must provide Bridge, I2C/SPI to UART conversion capability
• Protocol Support: Both parts must support I2C protocol
• Interface Type: Both parts must provide UART interface output
• Operating Temperature Range: Both parts must support -40°C ~ 85°C operation
• Compliance Standards: Both parts must maintain ROHS3 compliance and REACH Unaffected status

The PI7C9X760CZDEX meets all substitution criteria as a direct equivalent, with the primary distinction being product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The PI7C9X760CZDEX is a direct functional equivalent to the PI7C9X760BZDEX. Both components share identical core specifications, package geometry, and electrical interface characteristics. The PI7C9X760CZDEX is the recommended selection for new designs and ongoing production due to its Active product status, whereas the main part is classified as Obsolete.

Both parts maintain ROHS3 compliance and REACH Unaffected certification, meeting current environmental and regulatory requirements. The PI7C9X760CZDEX is available in Tape & Reel packaging format, suitable for automated assembly processes.

The voltage supply range specification differs between the two parts: the main part specifies discrete voltage levels (1.8V, 2.5V, 3.3V), while the substitute provides a continuous range (1.62V ~ 3.63V). This range specification in the substitute encompasses the discrete levels of the main part, ensuring compatibility in applications operating at the specified voltage levels.
