Mounting and termination specifics
Termination is solder — the header is designed for surface-mount reflow assembly. The insulation height is 0.224 inches (5.69 mm) above the board.
The SM02B-PASS-TBT (2 positions) and SM03B-PASS-TBT (3 positions) share identical pitch (2.00 mm), current rating (3 A), voltage rating (250 V), mounting (SMT right-angle), and locking ramp fastening. If your BOM calls for 3 positions, the SM03B-PASS-TBT is a direct drop-in in the same series. For 2 positions, the SM02B-PASS-TBT is the correct part.
