The Hirose DF51K-16DS-2C(800) is a 16-circuit, dual-row receptacle housing from the SignalBee™ DF51 series. 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.
