The Hirose DF9-9P-1V(61) is a 9-position, dual-row header with center strip contacts from the DF9 series. It uses a 0.039" (1.00mm) pitch and surface-mount termination, with gold plating on the contacts.
This header mates with the DF9-9S-1V(69) receptacle, which has outer shroud contacts and a matching 4.3mm stacking height. The 1.00mm pitch and dual-row layout mean the PCB footprint is compact — the board guide helps align the parts during assembly, and the solder retention features keep the connector in place through the SMT oven. The gold contact finish supports repeated mating cycles better than a tin-plated alternative, which matters if the boards see field service or rework.
