PH series, Board to Cable/Wire, 2-position, 2.00mm pitch, SMT shrouded header with detent lock, tin-plated contacts, 2A/100V, UL94 V-0, -25°C to 85°C, 8.6mm mated stack height.","salesMarkdown":"## What this 2-pin SMT header does in a board-to-wire link ## Footprint and assembly: SMT with solder retention Surface-mount termination with integrated solder retention tabs holds the header steady during reflow, reducing the risk of skew or tombstoning on the pick-and-place line. The mated stack height of 8.6mm gives the board layout engineer a clear z-axis constraint for enclosure clearance. Insulation height is 0.260\" (6.60mm) above the PCB, and the contact mating length is 0.130\" (3.30mm) — enough for a reliable wipe with the receptacle's female contacts. RoHS compliance is standard for the PH series; no separate certification document is listed, but the material declaration supports it. ## Mating half and peer comparison: picking the right position count The mating connector is a PH-series crimp receptacle housing with 2.00mm pitch female terminals — order the housing and terminals separately for a complete wire-to-board assembly. Within the same SM4-TB family, the B3B-PH-SM4-TB (3 positions), B5B-PH-SM4-TB (5 positions), and B6B-PH-SM4-TB (6 positions) share identical pitch, current rating, and SMT footprint — only the position count changes, so a 2-position BOM can be scaled up by swapping to a higher-count sibling without requalifying the footprint.","metaTitle":"JST B2B-PH-SM4-TB PH Series 2-Pin SMT Header, 2.00mm Pitch","metaDescription":"JST B2B-PH-SM4-TB: PH series 2-position SMT header, 2.00mm pitch, shrouded 4-wall, detent lock, 2A/100V.
