640468 datasheet(21/84 Pages) TEC

21 / 84 page

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. 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 12 and 13.

For mating half visuals, see

pages 14, 15 and 31.

Header Ordering

Information

The “Base Part Numbers”

Chart at right shows the base

part number.

Prefixes and suffixes are deter-

mined 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:

See page 15 for an explanation of

RoHS lead free equivalents.

Note: All RoHS equivalent part num-

bers may not be available upon cat-

alog 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.
