Product details

The B12B-PH-K-S(LF)(SN) is a 12-position, single-row header from the JST PH series, pitched at 2.00 mm. It mates with the corresponding PH-series crimp receptacle to make a wire-to-board connection. Tin-plated contacts are the economical choice for low-cycle applications.

Through-Hole Press-Fit Termination

The header terminates with press-fit, solder tails that go through the PCB and are wave-soldered. The 0.134" (3.40 mm) post length and 0.130" (3.30 mm) mating pin length give a total contact length of 0.333" (8.45 mm). The mated stack height is 8 mm — useful when the receptacle sits on a wire harness and the board needs a consistent z-height budget.

Frequently asked questions

What is the difference between B12B-PH-K-S and B12B-PH-K-S(LF)(SN)?

The (LF)(SN) suffix indicates lead-free and tin-plated contacts. Both parts share the same 12 positions, 2.00 mm pitch, 2 A rating, and mate with the same PH-series receptacle. The (LF)(SN) variant is the current standard; the non-suffixed version may be legacy stock.
