3-644466-2 Datasheet, PDF (46/84 Pages) Tyco Electronics – MTA, CST-100 II, SL-156 and AMP Economy Power

MTA, CST-100 II, SL-156 and
AMP Economy Power (EP) Connectors
MTA-156 Flat Headers—Straight
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. Gold headers are duplex plated,
gold on mating end of post and
tin on the solder tail.
3. .125 [3.18] solder tail lengths are
for .062 [1.57] thick printed circuit
boards and .175 [4.45] solder tail
lengths are for .093-.125 [2.36-
3.18] thick printed circuit boards.
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, see
pages 36 thru 39, 55, 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 and a .125
[3.18] solder tail length would be:
Base number 640383 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-640383-0
The part numbers in bold
face are the RoHS equivalent
version. Example:

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
