0.50mm Pitch FPC Plug — 20 Positions, 3mm Stack
Its 0.020" (0.50mm) pitch and 2-row layout pack 20 signal lines into a compact footprint — the kind of density you see in handheld or portable device mainboards. The outer shroud contacts give the plug a self-aligning mate with the matching receptacle, which helps avoid bent contacts during assembly on a 0.50mm pitch where misalignment tolerance is near zero. Gold contact finish is standard here, suited for the moderate mating cycles a production FPC connection sees before the assembly is locked down. Mated stacking height is 3mm — that is the full board-to-board gap once the plug is seated in its receptacle. For a 0.50mm pitch FPC interconnect, 3mm is about as low as it gets; it fits inside enclosures where the mezzanine clearance is measured in millimetres.
Obsolete — Sourcing the 20P3.0-JMCS-G-TF(N)
For a BOM line that still calls out this MPN, the supply channel is surplus and broker inventory.
At this pitch, the FPC thickness and stiffness matter: too thick a flex and the insertion force goes up; too thin and the contacts may not wipe properly. Gold plating on the contacts handles the insertion wear of assembly and rework without corrosion issues.
