Single-row housing profiles
The two housing profiles specify PA66. One table lists 2–15, 20, 25 and 30 positions; the other also lists 21. The housings are not interchangeable solely because their pitch matches.

Connector construction
Compare configuration options
Select the housing, contacts and mating connector together. The available circuit counts and materials depend on the specific drawing, rather than one range covering every variant.
SMT board profiles
Multiple right-angle and straight board constructions are shown, with PA9T, PA6T or LCP bodies and configuration-specific tin or gold finishes. Select the exact footprint and mating housing rather than a continuous position range.
