Material and Finish

Housing—UL94V-0 rated, polyester, white

Contacts—Copper alloy, tin plated,

.000030 [0.00076] or .000015

[0.00038] gold over nickel

Note:

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. To determine header overall length (dim. A)

multiply .100 x the number of posts. Example:

.100 x 10 posts equals 1.000 inch [25.4 mm].

For mateability options, see matrix on

pages 5 and 6.

For mating half visuals, see pages 7, 8

and 24.

Header Ordering Information

The “Base Part Numbers” Chart at right

shows the base part number.

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 would be:

Base number

641211 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-641211-0

All part numbers are the RoHS equivalent

version. Example:

No. of

Lead Free

Pos.

RoHS

Prefix/Suffix

3-641211–2

thru

5-641211-8

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: Select load headers (omitted pin headers) are

available upon request. Please contact product engi-
