The Hirose DF51-28DS-2C is a 28-position receptacle housing from the SignalBee DF51 series, built for wire-to-board crimp termination. It carries a 2.00 mm pitch across two rows, with the same 0.079" (2.00 mm) row spacing, so the contact footprint is a compact 28-position grid that mates with the matching DF51 pin header.
The dual-row layout with 28 positions means the header footprint is a 14-per-side staggered grid — the row spacing at 2.00 mm keeps the overall connector width under 10 mm. Against the 26-position DF51-26DS-2C, this part adds two contacts per row for a total of four extra circuits; against the 30-position DF51-30DS-2C, it drops two per row. The housing body and latch geometry are identical across the 16-, 26-, 28-, and 30-position variants, so the only fit difference is the number of cavities.
