3. One peg only on a 2 position
4. Headers with .00015 [0.00038]
5. To determine header overall
For mateability options, see
matrix on pages 34, 35, 54
and 58.
For mating half visuals, use
only connectors with a locking
ramp for polarization/retention
purposes, see pages 36 thru
39, 55, 60 and 62.
For polarizing purposes only
use connectors without a lock-
ing ramp. See pages 36 thru
39, 60 and 62.
Header Ordering
Information
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 front bend and
with pegs would be:
Base number 644617 plus
The correct ordering number is
The set of numbers in bold
face are the RoHS equivalent
version of the standard prod-
uct. Example:
See page 15 for an explanation of
RoHS lead free equivalents.
