640607 datasheet(52/84 Pages) MACOM

52 / 84 page

Material and Finish

Housing — UL94V-0 rated, nylon, black

Posts — Copper alloy, tin plated,

.000015 [0.00038] gold over nickel

Temperature— Maximum

Temperature Rating: 280°C

Notes:

1. Post(s) can be omitted for keying pur-

poses. 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. Headers with straight and right-angle

square posts are available upon

request. Minimums may apply.

4. To determine header overall length

(Dim. A), multiply .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 34, 35, 54

and 58.

For mating half visuals, use

connectors with a locking ramp

for polarization/retention pur-

poses, see pages 36 thru 39,

55, 60 and 62.

For polarizing purposes only

use connectors without a lock-

ing ramp. See pages 36 thru

39, 60 and 62.

Header Ordering

Information

The “Base Part Numbers”

Chart at right shows the base

part number and number of

posts available for the

described headers.

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 round tin plated posts:

Base number 647648 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-647648-0

The part numbers in bold

face are the RoHS equivalent

version. Example:

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
