The size of the lead (0.3mm, 0.5mm, 0.7mm, 0.9mm, 1.3mm, etc) is just the width of the lead. In a #2 pencil, the #2 refers to the hardness of the lead. This is where those little letters on the lead come into play on the lead refill packs. The ratings are like this:
(softer) (harder)
B6 B5 B4 B3 B2 B1 HB H1 H2 H3 H4 H5 H6
(darker) (lighter)
Most lead refill packs you buy from places like office max, target, bookstore, etc will be HB. Lead that comes with brand new mechanical pencils is almost always HB. This "mid-range" hardness is equivalent to #2 lead in a #2 pencil. The other kinds of lead are pretty much only sought after by drafters and you'll probably only find them in a drafting supply store or a specialty office store.
So the answer to your question: it probably is, but not because it's 0.7mm. rather, it probably is because HB lead is the most common and most likely to have come with your pencil.

Is 2mm larger than 3mm?
No. The units are the same (mm) so the numbers can be compared directly. 2 < 3 → 2 mm < 3 mm. → 2 mm is less than 3 mm, ie 2 mm is not larger than 3 mm.
Which is greater 10inchs or 200mm?
Convert to the same units, then the comparison can be made: 1 in = 25.4 mm → 10 in = 10 × 25.4 mm = 254 mm 254 > 200 → 254 mm > 200 mm → 10 in > 200 mm 10 in is greater than 200 mm
Which is greater 15cm or 150mm?
Since 1 cm = 10 mm, they are the same.15 cm = 150 mm
Is a 7 mm mechanical pencil the same as a number 2 pencil?
