If the lot size is 100,000, the lot size does not have any effect on the binomial sample size calculation for samples less then 100,000/10=10,000. Since you probably don't intend to take that big a sample you can neglect lot size. It has no measurable effect.
On the other hand, if you had a lot size of 20, you would violate that rule if the calculated turned out to be n=5, n=10, n=20, or n=30.
