Board Fit and Routing Reality
The BM14B-SRSS-TBT(LF)(SN): This is a 14-position, single-row, surface-mount header from JST's SH/SR series. The push-pull latch holds the mated pair without tools.
Mating Half and Build-to-Print BOM
The mating connector is the JST SH series receptacle housing (e.g., part number starting with SHR-14V-S) plus the appropriate crimp terminals (SSH-003T-P0.2 or equivalent). The 4.9 mm mated stack height means the header and receptacle together occupy just under 5 mm of z-height — important for tight enclosures. For a complete assembly BOM, you need: this header (BM14B-SRSS-TBT(LF)(SN)), the matching receptacle housing, and the crimp terminals. The header comes with solder retention features and is pick-and-place compatible — the tape-and-reel packaging suits automated assembly.
The closest sibling is BM14B-SRSS-TB — identical in every spec except it lacks the pick-and-place feature. If your assembly line uses vacuum pick-and-place, the -TBT suffix version (this part) is the correct choice. The 13-position variant BM13B-SRSS-TBT(LF)(SN) shares the same pitch, current rating, and stack height — just one fewer circuit.
