It uses a 2.00mm pitch and a 2.00mm row spacing, giving a compact footprint for wire-to-board harnesses where board space is tight. ## Sizing the Harness: Circuit Count and Pitch The 16 positions at 2.00mm pitch give this housing a 32.00mm nominal width across two rows. If the BOM calls for 16 signal lines, this housing matches without wasted positions; the 18-position DF51K-18DS-2C(800) is an option if an extra pair of circuits is needed for future expansion. ## Termination and Contact Selection The crimp termination allows the harness builder to attach wires before inserting them into the housing, which is standard practice for field-serviceable or low-to-medium volume assemblies. ## Material and Operating Range The housing is rated -55°C to 105°C. The black color is standard for the DF51 series. ROHS3 compliance is on record, so the part clears EU material restrictions without a waiver.","metaTitle":"Hirose DF51K-16DS-2C(800) Receptacle Housing, 16 Pos 2.00mm","metaDescription":"Hirose SignalBee DF51K-16DS-2C(800) receptacle housing, 16 circuits, 2.00mm pitch, dual-row, locking ramp.
