Sizing the Footprint and Contact Duty
The 2-84984-5: 25 positions on 1.00 mm pitch — the board footprint needs a trace channel every 0.039" for the full row. Rated 1 A per contact with tin plating. Tin is the economical choice for low-cycle mating: expect 20–30 insertions before the contact force degrades. For a cable that mates once during assembly and stays, tin is fine.
Vertical Orientation and FFC Fit
The vertical contact arrangement (contacts on one side) mates with a straight FFC or FPC — the cable enters perpendicular to the board. The 0.30 mm FFC thickness is the target; the contact beam is designed for that stack-up. Height above board is 0.220" (5.59 mm). This sets the z-height budget in the enclosure — enough clearance for the cable bend radius after the connector.
