CROSS REFERENCE
DF12 Compatible 0.5mm Board-to-Board Connector (B104)
The B104 series maps to DF12: 0.5mm pitch, 10–80 pins and 3.0–5.0mm stack heights, laid out on the original footprint for direct substitution in camera modules, industrial and automotive boards.
Specification and pairing
B104 covers 10 to 80 pins with 3.0 / 3.5 / 4.0 / 4.5 / 5.0mm stack steps, plug and receptacle paired by height. The 0.5mm pitch balances routing density against placement yield, which is why it dominates module designs.
Points to check when replacing DF12
1) The stack height must match the mechanical design; one step off will cause pre-load or incomplete mating. 2) At 80 pins, review retention at both ends and add locating pegs if needed. 3) Camera modules often mix BTB with FPC, so check the combined Z height.
Common applications
Phone and tablet camera modules, automotive cameras, security cameras, industrial mainboards and expansion boards, robot vacuum and mower board stacking.
