Substitute Part Grouping Explanation

Substitution of the SI3018-FS is based on strict equivalence of the following critical parameters:

• Function: Direct Access Arrangement (DAA) implementation
• Interface Compatibility: Parallel, SPI, and UART support
• Circuit Count: Single circuit configuration
• Electrical Specifications: 3V ~ 3.6V supply voltage, 8.5mA supply current
• Operating Temperature Range: 0°C ~ 70°C
• Package Specification: 16-SOIC form factor with 0.154" (3.90mm) width
• Mounting Technology: Surface mount configuration

The SI3018-F-FS meets all substitution criteria as an active product variant of the same base product number (SI3018) with identical electrical and mechanical specifications.
