The DDPAK/TO-263-9 is a surface-mount package with an exposed pad (9 leads plus tab). The tab is the main thermal path — the PCB layout must have a thermal land and vias to a ground plane. The part is available in Tape & Reel or Cut Tape, so it suits both prototype assembly and production reflow.
The LM4950TSX/NOPB is listed as Active with no LTB or NRND flags. ROHS3 compliant. No official replacement is published because none is needed.
Yes, it can be configured as a 2-channel (stereo) amplifier delivering 3.1W per channel into 4Ω loads, or as a single mono channel at 7.5W into 8Ω.
