The Hirose DF14-15S-1.25C(10) is a 15-position, single-row receptacle housing from the DF14 series, built for wire-to-board interconnects at a 1.25 mm pitch.
At 1.25 mm pitch, this is a compact wire-to-board connector — tighter than the common 2.00 mm or 2.54 mm headers, so it saves board real estate but demands a matching narrow-pitch PCB footprint. The trade-off is that the tight pitch limits the current per contact compared to a wider-pitch connector — the housing itself doesn't carry a current rating (that depends on the crimp terminal chosen), but the 1.25 mm centerline typically pairs with contacts rated around 1 A per circuit in practice.
It's ROHS3 compliant, so it clears the EU material restriction without a waiver. No last-time-buy window to watch, no forced alternate evaluation.
The matching pin header for the PCB side is the DF14-15P-1.25C (or the equivalent through-hole variant).
The DF14-15S-1.25C(10) shares the same 1.25 mm pitch, single-row layout, beige PA nylon body, and free-hanging crimp termination as the DF14-6S-1.25C(10). If your harness calls for 15 wires, this is the housing — the 6-position sibling won't fit the BOM line. Both are active and ROHS3 compliant, so the choice is purely a circuit-count match.
