The housing ships empty — order the terminals separately
The Hirose DF3-3S-2C is a 3-position receptacle housing from the DF3 series, a 2.00 mm pitch wire-to-board interconnect family.
Where the 3-position fits in the DF3 line
The DF3-3S-2C is the 3-circuit member of the DF3 receptacle housing family. The same housing design, pitch, and material are shared across the 2-position DF3-2S-2C and the 4-position DF3-4S-2C — the only difference is the cavity count. If the BOM calls for a 3-circuit inline splice, this is the housing; a 2-circuit or 4-circuit application needs the respective sibling.
