Product details

Board Fit and Pinout

The B8B-PH-SM4-TBT(LF)(SN): The 2 A per-contact rating at 100 V suits signal and low-power distribution inside control panels, sensors, and consumer electronics. 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.
