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].

Information
Note: Consult Product Drawing for details
on placing headers onto PC boards.
The “Base Part Numbers”
Chart at right shows the base
part number and number of
posts available for the
described headers.
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:
Base number 640383 plus
