Material and Finish

Housing — UL94V-0 rated, polyester,

black

[0.00038] gold over nickel

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 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 avail-

able upon request. Minimums may apply.

For mateability options, see

matrix on pages 34, 35, 54

and 58.

For mating half visuals, see

pages 36 thru 39 and 55.

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 straight, square

posts and with pegs would be:

Base number 647127 plus

prefix-and-suffix

4- — -0

The correct ordering number is

4-647127-0
