Note: All part numbers are RoHS compliant.
The letter A stamped
on contact indicates
mating end of recep-
tacle.
This configuration recommended
for use with machine applied posts
or headers with a .405 [10.29]
minimum mating end post length.*
The mating post length is depicted by the A dimension on page 294 (machine applied posts) and the C dimension on
pages 295-297 (headers).
H-Receptacle centers may vary depending on requirements. For individual receptacles, minimum nominal centerline
spacing between adjacent receptacles is .125 [3.18] for receptacle assemblies, centerline spacing between adjacent
receptacles is .156 [3.96]. The .003 [0.08] tolerances are not to accumulate over length of board.
