JST LEA 2-Position SMT Header — SM02B-LEASS-TF
It carries a 0.071" (1.80mm) pitch — tight enough for compact layouts but wide enough to keep routing straightforward for a 2-circuit run.
The 0.071" (1.80mm) pitch is the critical board-layout dimension — it sets the pad spacing and rules out any 2.00mm or 2.54mm footprint. The solder retention pads add mechanical hold beyond the signal pins alone, which matters when the mated cable is routed near the connector.
The 2-position count must match the receptacle's cavity count — a 2-circuit cable assembly is the intended mate. Termination is solder to the board; the cable side uses a separate crimp terminal and housing, not included here.
