Sounds like the same stuff, though I have 2002 on mine (which in absence of
other markings was cryptic enough that I was unsure of it, though I think it
might have been earlier than 2002 when I found it. I thought it might be
75 ohm but I had no idea it might efficiently carry high power. But I knew it
was well over-spec'd for the uses I put it to. I was lucky to find it. The
staff there were happy enough for me to raid the skip, too... Should try it
again sometime. That stuff seems to last forever even outside in strong daily
temperature changes and direct sunlight.

If it has 2002 printed on it, that means it's "Cable coaxial 2002",
which is one down the scale in loss terms from 2003. 2002 (nothing to do
with the date!) is as good quality as 2003 (which is thicker), but the
loss is a bit higher. The three usual types were AFAIR -

2001 - single screened, foam dielectric. Quite thin - used for short
runs and jumpers.
2002 - General purpose, high quality. Solid dielectric.
2003 - Top quality (in loss terms). Solid dielectric.

All are 75ohms - like pretty well all telecom coax. (50 ohm is usually
only found in antenna feeders and traditional ethernet). The normal PVC
jacket colour was "Light straw" (yellowish cream), but other colours
were occasionally used for special purposes.
