MTA, CST-100 II and SL-156 Connectors

MTA-156 Shrouded Headers—Straight and Right-Angle

Material and Finish

Housing—UL94V-0 rated, polyester, black

Posts—Copper alloy, tin plated; or

.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-lead on the solder tail.

3. Peg holes are not required in PC boards when

headers without pegs are used.

4. One peg only on a 2 position header, other position

sizes have two pegs.

5. Right-angle front and rear bend headers with

retention pegs can be made available upon request.

Minimums may apply.

For mateability options, see matrix on

pages 27, 28, and 47.

For mating half visuals, see pages 29 thru 32.

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 head-

er. For example, the complete part num-

ber for a 10-position header with straight,

square posts and with pegs would be:

Base number

647127 plus
