No stock-holding claim – each RFQ is sourced through independent distribution. The SM02(4.0)B-BHS-1-TB(LF)(SN) is the 2-position version of this same header – identical pitch, orientation, plating, and ratings. If your BOM calls for 2 positions, that part saves one circuit of PCB real estate; if you need 3, this is the one. The non-LF(SN) variant SM03(4.0)B-BHS-1-TB is electrically identical but may not carry the same RoHS documentation suffix – verify your compliance requirement before substituting.","metaTitle":"JST SM03(4.0)B-BHS-1-TB(LF)(SN) – BH Series 3-Pin","metaDescription":"JST BH series 3-position male header, 4.00 mm pitch, right-angle SMT, tin-plated contacts, UL94 V-0, RoHS.
