People are seeing a lot of variability in Titan Drive Component drop-rates. I tried for hours at Cocijo and never found any (including going back with an Anaconda equipped with 8A sensors). Eventually gave up, set a buy-order on my Carrier at maximum price, and got 9 of them (my thanks to those who sold them to me).
I have two alts, my "assistants" (one based in the Bubble and one in Colonia), I sold them 2 each. My Bubble assistant needed Propulsion Elements and went to Sol to get them, and still didn't find any TDC's. After my Colonia alt went to the Bubble and did the same, I accidentally found another five TDC's. That alt doesn't have a Sol permit, and went to Pegasi Sector IH-U b3-3 (Raijin) instead, dunno if that made any difference. And that ship (a T8) only had unengineered 3A sensors.
