MTA-100
.100 [2.54]
Material and Finish
Housing — UL94V-0 rated, polyester,
white
Posts — Copper alloy, tin plated,
.000030 [0.00076] or .000015
[0.00038] gold over nickel
Notes:
1. Post(s) can be omitted for keying
purposes. Specify the desired
post(s) to be omitted using the
figure to identify Post No. 1.
2. Headers without retentive legs are
suitable for breakaway application.
3. 2 or 3 retentive leg(s) per header,
depending upon number of positions.
4. Gold headers are duplex plated,
gold on mating end of post and
tin on the solder tail.
5. To determine header overall
length (dim. A) multiply .100 x the
number of posts minus (–) .012.
Example: .100 x 10 posts – .012
= .988 inches [25.1 mm].
For mateability options, see
matrix on pages 12 and 13.
For mating half visuals, see
pages 14, 15 and 31.
Connector Ordering
Information
The “Base Part Numbers”
Chart at right shows the base
part number.
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
without retentive legs would be:
Base number 644456 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-644456-0
All part numbers are the RoHS
equivalent version. Example:
No. of

Prefix/Suffix
2 3-644456-2
thru
28 5-644456-8
See page 15 for an explanation of
RoHS lead free equivalents.
Note: All RoHS equivalent part num-
bers may not be available upon cat-
