Tapconing into a mortar joint is to be avoided.

See the discussion here.

And the one here about how 3/16" are garbage. Use 1/4".

If the Tapcon goes into a mortar joint it's pull out strength will depend on the compressive PSI of the mortar and the depth of the mortar joint in combination with the length & diameter of the Tapcon.
