The -25°C to 85°C range covers most indoor and sheltered outdoor gear. ## Mounting and Assembly The 8.6 mm mated stack height and 6.60 mm insulation height mean the header stands off the board enough to clear components under the receptacle body. ## Mechanical Protection and Mating For higher cycle life, the gold-plated PH variants are a better fit. ## Peer Comparison: 8 vs 9 Positions If your BOM calls for 8 positions, this is the correct count; the 9-position variant adds 2 mm to the board footprint.","metaTitle":"B8B-PH-SM4-TBT(LF)(SN) JST PH 8-Pos 2mm SMT Header","metaDescription":"JST PH series 8-position SMT header, 2.00mm pitch, shrouded 4-wall, detent lock, 2A/100V rated.
