MTA-156
.156 [3.96]
Material and Finish
Housing —UL94V-0 rated, nylon, black
Posts — Copper alloy, tin plated,
.000015 [0.00038] gold over nickel
Temperature— Maximum
Temperature Rating: 280°C
Notes:
1. Post(s) can be omitted for keying pur-
poses. Specify the desired post(s) to
be omitted using the figure to identify
Post No. 1.
2. Gold headers are duplex plated, gold
on mating end of post and tin-lead on
the solder tail.
3. Headers with straight and right-angle
square posts are available upon
request. Minimums may apply.
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].
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 round tin plated posts:
Base number 647648 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-647648-0
The part numbers in bold
face are the RoHS equivalent
version. Example:
No. of
Lead Free
Pos.
RoHS
Prefix/Suffix
2 3-647648–2
12 4-647648-2
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.
