Pitch, current rating, voltage, mounting orientation, shrouding, and latch type are identical. If your BOM calls for 4 positions, order the SM04B variant — no other spec changes.","metaTitle":"SM03B-NSHSS-TB (LF)(SN) JST NSH 3-Pin Header, 1.00mm Pitch","metaDescription":"JST NSH series 3-position shrouded header, 1.00mm pitch, 1 A, 50 V, SMT right-angle, tin contacts, UL94 V-0.
