The 2.54mm Dual Row Pin Header 40 Pin DW-PH-2254798WV40P-01PE-01 is a vertical 2 × 20 through-hole PCB header with 2.54 mm pitch and 0.64 mm square copper-alloy pins. It features a 3 A current rating, gold-flash contact plating, UL 94V-0 insulation, PE-bag packaging, and RoHS-compliant construction.
Applications: Board-to-board interconnection, wire-to-board interfaces, industrial control boards, embedded electronics, communication equipment, instrumentation, test equipment, development boards, and general PCB assemblies.
Highlights: 2.54 mm pitch; 40 pins; 2 × 20 dual-row configuration; vertical DIP/through-hole mounting; 3 A rated current; ≤20 mΩ contact resistance; ≥1000 MΩ insulation resistance; 1000 V AC/DC dielectric withstand; -40°C to +105°C operating range; 0.64 mm square pins; copper-alloy contacts; gold-flash plating; Polyester/PA6T UL 94V-0 insulation; 6.0 ±0.2 mm mating pin; 3.0 ±0.2 mm PCB tail; A = 48.26 mm; B = 50.80 mm; Ø1.10 mm PCB holes; PE-bag packaging; RoHS compliant.
2.54mm Dual Row Pin Header 40 Pin DW-PH-2254798WV40P-01PE-01 is a vertical through-hole PCB connector designed with 40 contacts arranged in a 2 × 20 configuration. The Dragon Well drawing confirms a 2.54 mm pitch, 0.64 mm square pins, dual-row construction, and DIP/through-hole termination for secure PCB mounting.
This connector is rated at 3 A. Its electrical specifications include 20 mΩ maximum contact resistance, 1000 MΩ minimum insulation resistance, and 1000 V AC/DC dielectric withstand. The specified operating temperature range is -40°C to +105°C.
The 2.54mm Dual Row Pin Header 40 Pin uses copper-alloy contacts with gold-flash plating for this specific 01 plating configuration. The drawing lists the insulation material as Polyester / PA6T, UL 94V-0. Resistance to soldering heat is specified at 260°C ±5°C for up to 10 seconds.
For this 40-position model, the dimension table specifies A = 48.26 mm and B = 50.80 mm. The mating pin length is 6.0 ±0.2 mm, the PCB tail length is 3.0 ±0.2 mm, and the insulator height is 2.50 ±0.10 mm. The recommended PCB layout uses Ø1.10 mm holes on a 2.54 mm × 2.54 mm grid. Packaging code PE identifies PE-bag packaging.
The 2.54mm Dual Row Pin Header 40 Pin is suitable for board-to-board connections, wire-to-board interfaces, industrial control boards, embedded electronics, communication equipment, instrumentation, test equipment, and general PCB interconnection. Molex, Samtec, and Amphenol use the same established terminology for comparable 2.54 mm, 40-position, dual-row, vertical through-hole PCB headers.
