    AI Overview
    The TS3A44159PWRG4 (IC SWITCH SPDTX4 450MOHM 16TSSOP) from Texas Instruments is considered a discontinued or "end-of-life" part by some distributors, though it is often replaced by identical, active counterparts
    . 
    Top Alternatives and Replacements 
    • TS3A44159PWR: This is the direct, active, and recommended replacement from Texas Instruments. It has the same 0.4-Ω (nominal) on-state resistance, quad SPDT configuration, and 16-TSSOP package.
    • TS3A44159RSVR: A suitable alternative if a smaller package is acceptable. This is the UQFN (RSV) package version, which is also active.
    • TS3A44159RGTR: Another active alternative, this time in the VQFN (RGT) package.
    • RS2099XTSS16: Identified as a functional replacement part, often marketed as a compatible option. 
    Key Technical Specifications (for validation) 
    • Function: 4-Channel, 2:1 (SPDT) Analog Switch
    • On-State Resistance (
      RONcap R sub cap O cap N end-sub
      𝑅𝑂𝑁
      ):       0.4 Ω (Typical)
    • Package: 16-TSSOP
    • Supply Voltage: 1.65 V to 4.3 V
    • Bandwidth: 23ns, 32ns 
    It is recommended to check stock for the TS3A44159PWR first, as it is the direct, non-"G4" (lead-free/green) equivalent, which is frequently still in stock.
