.000030 [0.00076] gold over nickel
Notes:
1. Post(s) can be omitted for keying pur-
2. Peg holes are not required in
3. One peg only on a 2 position header,
4. Headers with .00015 [0.00038] gold
5. To determine header overall length
For mateability options, see
matrix on pages 34, 35, 54
and 58.
For mating half visuals, use
connectors with a locking ramp
for polarization/retention pur-
poses, 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 square posts with
pegs would be:
Base number 644615 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.
