Alternative Part Number

  • SI3050-FT --: Same Silicon Labs voice/telephony line interface family with comparable functionality and package, often used as a direct substitute in similar designs.
  • SI3210-FT --: Silicon Labs ProSLIC line interface device with similar telephony interface role, suitable when the design can accommodate its feature set.
  • LE88221DLC --: Alternative voice line interface IC from a different vendor offering comparable subscriber line interface functionality for cross-vendor sourcing.
  • SI3050-F-FT --: Same Silicon Labs direct-access-arrangement (DAA) family in the same FT (TSSOP) package, offering comparable line-side functionality and a common drop-in option for many designs.
  • SI3018-F-FT --: Closely related Silicon Labs DAA/line-side device in the same package and pin family, often used as a functional substitute where the SI3019 variant is unavailable.
  • SI3210-F-FT --: Silicon Labs ProSLIC/telephony interface device in a similar TSSOP package; a viable alternative when the specific SI3019 DAA function can be reworked, though pinout and firmware checks are required.
  • LE58QL021 --: Alternative voice-band codec/SLIC interface IC from a different vendor series offering similar telephone line interface functionality for designs needing a second source.
