MTA, CST-100 II and SL-156 Connectors

MTA-156 Friction Lock 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 print-

ed circuit boards.

4. To determine header overall length (Dim. A), mul-

tiply .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 27, 28, and 47.

For mating half visuals, use connectors

with a locking ramp for polarization/re-

tention purposes, see pages 29 thru 32,

48, 53 and 55.

For polarizing purposes only use connec-

tors without a locking ramp. See pages

29 thru 32, 49 and 51.

Header Ordering Information

The “Base Part Numbers” Chart at right

shows the base part number and num-

ber 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 and a .125 [3.18] solder tail

length would be:

Base number

641208 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-641208-0
