Material and Finish

Housing—UL94V-0 rated, polyester, black

Posts—Copper alloy, tin plated, or

.000030 [0.00076] gold over nickel

Notes: 1. Post(s) can be omitted for keying purposes.

Specify the desired post(s) to be omitted

2. Headers with .000015 [0.00038] gold plated

post are available upon request. Minimums

may apply.

3. Gold headers are duplex plated, gold on

mating end of post and tin on the solder tail.

For mateability options, see matrix on

pages 5 and 6.

For mating half visuals, see page 23.

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

straight posts and with pegs would be:

Base number

644893 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-644893-0

All part numbers are the RoHS equivalent

version. Example:

No. of

Lead Free

Pos.

Prefix/Suffix

3-644893-2

thru

4-644893-4

See page 8 for an explanation of RoHS lead free

equivalents.

Note: All RoHS equivalent part numbers may not be

available upon catalog release. If the number you need

is not available, please contact Product Engineering to

expedite your request.

Note:

CST-100 II shrouded headers only mate with CST-100 II

housings. All the MTA-100 headers except the MTA-100

shrouded headers mate with CST-100 II housings.
