3. .125 [3.18] solder tail lengths are
for .062 [1.57] thick printed circuit
boards and .175 [4.45] solder tail
lengths are for .093-.125 [2.36-
3.18] thick printed circuit boards.
4. To determine header overall
length (Dim. A), multiply .156 x
the number of posts. Example:
.156 x 10 posts equals 1.560
inches [39.62 mm].

The “Base Part Numbers”
Chart at right shows the base
part number and number of
posts available for the
described headers.
Base Part Numbers
Prefixes and suffixes are deter-
mined by the number of post
positions in the header. For
example, the complete part
number for a 10-position header
with square posts and a .125
[3.18] solder tail length would be:
