0.80mm pitch, 100 positions — the board-routing budget
The Amphenol FCI 61083-102502LF is a BergStak® 0.80mm plug with center strip contacts, 100 positions in two rows. At 0.031" (0.80mm) pitch, the trace escape from each row demands a microvia or tight dog-bone pattern — this is a high-density mezzanine interconnect, not a general-purpose header. The 100-circuit count matches a wide parallel bus or a dense FPGA-to-carrier interface where every signal needs its own lane.
Active production — no LTB watch needed
Listed as Active in the lifecycle record. For a new design at this density, the BergStak 0.80mm series is a current-production choice with no forced migration risk.
