Board-fit reality for the 2-pin SMT header
The SM02B-SRSS-TB is a JST SH/SR series header — 2 positions, single row, 1.00 mm pitch, terminating via surface-mount right-angle solder tails.
What the 1 A rating means for your circuit
The 50 V ceiling keeps it inside safe low-voltage territory. The tin-on-tin contact interface (mating and post) is cost-effective but limits mating cycles compared to gold.
The SM02B-SRSS-TB is RoHS non-compliant per the listing. If your build requires RoHS, check the (LF) suffix variant — SM02B-SRSS-TB(LF)(SN) — which is the lead-free equivalent.
Mates with JST SH/SR series crimp-style receptacles (e.g., the 2-position housing + terminals).
