The 84534-8: The 0.049" (1.25mm) pitch sets the PCB land pattern spacing — at this pitch, the board layout engineer budgets 1.25 mm centre-to-centre between adjacent FPC traces, which keeps routing density high enough for compact handheld or panel-mount designs. Eight positions in a single vertical row; the through-hole kinked pin termination locks the connector into the board during wave solder, so the assembly stays put through the reflow cycle without secondary retention hardware. Mates with a standard 0.30 mm thick FFC cable — the tapered cable end type guides insertion without stubbing the contacts.
ROHS3 compliant, with a white glass-filled PBT housing. No official pin-compatible replacement or cross-reference is listed from TE Connectivity.
