Material and Finish
Housing — UL94V-0 rated, nylon,
black
Contacts — High conductivity copper
alloy, post tin plated
For mateability options, see
matrix on page 54.
For strain relief and dust
covers, see pages 40
and 41.
For mating half visuals, see
pages 46 thru 48 and 50,
52 and 53, (49 and 51 Front
Bend Headers only). Mates
with tin-plated square
posts
only.
Refer to pages 70 thru 74
for approved wire listing.
Note: To determine connector overall
length (Dim. A), multiply .156 x the
number of circuits. Example: .156 x
10 circuits equals 1.560 inches
[39.62 mm].
Note: Tyco Electronics does not rec-
ommend terminating an MTA contact
more than one time. Use replace-
ment contacts when required for
field repairs or wire gage changes.

Information
The “Base Part Numbers”
Chart above shows the base
part number and number of
circuits available for the
described connectors.
Prefixes and suffixes are deter-
mined by the number of circuit
positions in the connector. For
example, the complete part
number for a 10-position
closed end connector with
locking ramp and without
polarizing tabs for 18 AWG
wire would be:
Base number 644329 plus
prefix-and-suffix
1- — -0
The correct ordering number is
1-644329-0
The set of numbers in bold face
are the RoHS equivalent ver-
sion of the standard product.

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
