It accepts crimp socket contacts terminated to discrete wires and mates with the corresponding LEA series pin header — the SM02B-LEASS-TF being the surface-mount, right-angle header that completes the board connection.
This housing accepts JST LEA series socket crimp contacts — the exact terminal part number is not listed here, but the 3 A rating at 22 AWG gives the wire gauge target for the crimp barrel. Mating is with a 2-position LEA series pin header; the SM02B-LEASS-TF is one production surface-mount option with tin-plated contacts and solder retention features. Confirm the header's orientation (right-angle vs. vertical) and board lock style against your assembly process before committing the BOM.
