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 straight posts and
with pegs would be:
Base number 644893 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-644893-0
All part numbers are the RoHS
equivalent version. Example:
No. of
Lead Free
Pos.
RoHS
Prefix/Suffix
2 3-644893-2
thru
14 4-644893-4
See page 15 for an explanation of
RoHS lead free equivalents.
Note: All RoHS equivalent part num-
bers may not be available upon cat-
alog release. If the number you
need is not available, please contact
Product Engineering to expedite
your request.
Note:
CST-100 II shrouded headers only
mate with CST-100 II housings. All
the MTA-100 headers except the
MTA-100 shrouded headers mate
with CST-100 II housings.
