MTA-156 Friction Lock Headers—Right-Angle
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 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 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.
When using Front Bend
Headers — for mating half
visuals use connectors with a
locking ramp for polarization/
retention purposes. When using
Rear Bend Headers — for mating
half visuals use connectors with-
out a locking ramp. For polariza-
tion purposes only 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
determined by the number
of post positions in the header.
For example, the complete part
number for a 10-position header
with square posts, front bend,
and a .125 [3.18] solder tail
length would be:
Base number 641210 plus
prefix-and-suffix
1- — -0
The correct ordering number is
1-641210-0
The set of numbers in bold
face are the RoHS equivalent
version of the standard prod-
uct. Example:
No. of Standard
Lead Free
Pos. Prefix/Suffix
RoHS
Prefix/Suffix
2 641210–2 3-641210–2
thru
24 2-641210-4 5-641210-4
See page 15 for an explanation of
RoHS lead free equivalents.
