3-644043-4 Datasheet, PDF (50/84 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 Polarized Lock Headers—Straight
Material and Finish
Housing — UL94V-0 rated, polyester,
white
Posts — Copper alloy, tin plated or
.000030 [0.00076] gold over nickel
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. Peg holes are not required in
PC Boards when headers without pegs
are used.
3. One peg only on a 2 position header,
other position sizes have two pegs.
4. Headers with .00015 [0.00038] gold
plated post are available upon request.
Minimums may apply.
5. 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 square posts with
pegs would be:
Base number 644615 plus
prefix-and-suffix
4- — -0
The correct ordering number is
4-644615-0
The part numbers in bold
