The 02R-LEBSS-TB: It uses a 0.157" (4.00mm) pitch, which gives enough room for a 3 A per circuit rating at 300 V without forcing a wide board footprint.
Mating Header and Termination
This receptacle mates with the JST 02P-LEBSS-TF(LF)(SN) plug, a 2-position SMT header with the same 4.00mm pitch and tin-plated contacts. The right-angle orientation on both halves keeps the mated pair parallel to the board.
The 4.00mm pitch sets the board footprint — each contact pad sits on that centreline, so the layout needs 4.00mm between the two positions. The solder retention tabs are not a lock — they prevent the part from lifting off the pad during reflow and under light vibration, but they don't replace a secondary mechanical latch.
