The 2.50mm Right Angle Wafer Connector 2 Pin DW-WF-125078WR02P-31PE-01 is a single-row, 90° DIP/through-hole connector with 2.50 mm pitch, 3 A / 250 V AC/DC rating, 0.64 mm square brass terminals, tin plating, white Nylon 66 UL 94V-0 housing, PE-bag packaging, and RoHS-compliant construction.
Applications: Wire-to-board connections, industrial control boards, home appliances, consumer electronics, embedded systems, communication equipment, instrumentation, and compact PCB assemblies.
Highlights: 2.50 mm pitch; 2 positions; single-row construction; 90° right-angle orientation; DIP/through-hole mounting; 3 A AC/DC rating; 250 V AC/DC rating; ≤20 mΩ contact resistance; ≥1000 MΩ insulation resistance; 1000 VAC/1 minute withstand voltage; -25°C to +85°C operating temperature; 0.64 ±0.05 mm square brass terminals; Sn/tin plating; white Nylon 66 UL 94V-0 housing; Ø1.02 mm recommended PCB holes; A = 2.50 mm; B = 7.50 mm; PE-bag packaging; RoHS compliant.
2.50mm Right Angle Wafer Connector 2 Pin DW-WF-125078WR02P-31PE-01 is a single-row, 90° through-hole PCB connector designed for compact wire-to-board interconnection. The Dragon Well drawing confirms a 2.50 mm pitch, 2-position configuration, DIP mounting, and 0.64 ±0.05 mm square brass terminals. For this specific 2-pin model, the dimension table specifies A = 2.50 mm and B = 7.50 mm.
The connector is rated at 3 A AC/DC and 250 V AC/DC. Electrical performance includes 20 mΩ maximum contact resistance, 1000 MΩ minimum insulation resistance, and 1000 VAC withstand voltage for one minute. The specified operating temperature range is -25°C to +85°C.
This 2.50mm Right Angle Wafer Connector 2 Pin uses brass terminals and a white Nylon 66 insulator rated UL 94V-0. The specific model uses plating code 31, which the drawing identifies as Sn/tin plating. Packaging code PE specifies PE-bag packaging, and the product is marked RoHS compliant.
The recommended PCB layout uses 2.50 mm terminal spacing with Ø1.02 mm PCB holes, supporting standard through-hole installation. Its right-angle construction allows the mating interface to remain parallel to the PCB, helping accommodate assemblies where vertical clearance is limited.
The 2.50mm Right Angle Wafer Connector 2 Pin is suitable for industrial control boards, consumer electronics, home appliances, embedded systems, communication equipment, instrumentation, and other wire-to-board PCB connections. Molex uses the same industry terminology for 2.50 mm pitch, single-row, right-angle, through-hole wire-to-board PCB headers, supporting the product naming used here.
