It uses a 0.016\" (0.40mm) pitch across two rows, with a height above board of 0.057\" (1.45mm) and a mated stacking height of 1.5mm. The contacts are finished with 2.00µin (0.051µm) gold — a thin flash suited for signal-level current in compact, low-profile assemblies. This connector is typically specified for internal board-to-board interconnects in portable electronics, handheld devices, and other space-constrained applications where the 1.5mm stack height fits a tight z-axis budget. The 0.40mm pitch drives the PCB footprint — it demands a fine-pitch layout and a mating header with the same 0.40mm spacing. The 1.45mm height above board, combined with the 1.5mm mated stack height, sets the z-axis clearance: this connector fits into assemblies where the total board-to-board gap is tight, such as smartphone or wearable enclosures. For designs needing extra board retention, the DF40B variant with solder retention features is a direct alternative at the same pitch and height. ## Comparing Position Counts Within the DF40C Family The DF40C-10DS-0.4V(51) carries 10 positions, while the DF40C-20DS-0.4V(51) offers 20 positions and the DF40C-100DS-0.4V(51) provides 100 positions — all at the same 0.016\" (0.40mm) pitch, 1.45mm height, and gold plating thickness. No other functional specs differ across these three members.","metaTitle":"Hirose DF40C-10DS-0.4V(51) Receptacle, 10 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-10DS-0.4V(51) receptacle, 10 positions, 0.40mm pitch, 1.45mm height, gold contacts.
