The 2.54mm 20 pin SMT female header is a 2 × 10 dual-row, vertical surface-mount PCB receptacle with an 8.50 ± 0.20 mm high-profile body. It is rated at 3.0 A and 250 V AC/DC and features copper-alloy contacts with gold plating over a minimum 50 µin nickel underplate. The PA6T housing is black, heat resistant, UL94 V-0 rated, and RoHS compliant.
The 2.54mm 20 pin SMT female header is a high-profile, dual-row PCB receptacle designed for vertical surface-mount board-to-board connections. The supplied photograph confirms a 2 × 10 contact arrangement with 20 total positions, while the engineering drawing specifies a 2.54 mm contact pitch and vertical 180° mating orientation.
For the 20-position configuration, the drawing gives a contact span, DIM A, of 22.86 ± 0.25 mm and an overall body length, DIM B, of 25.90 ± 0.35 mm. The black connector housing is 5.00 mm wide and 8.50 ± 0.20 mm high. Its installed height from the PCB surface is 8.80 ± 0.30 mm, and the formed SMT terminals have an overall span of 7.30 ± 0.35 mm.
The 2.54mm 20 pin SMT female header is rated at 3.0 A and 250 V AC/DC. Electrical performance includes 20 mΩ maximum contact resistance, 1,000 MΩ minimum insulation resistance, and a dielectric withstand rating of 500 V AC for one minute. The specified operating-temperature range is -40°C to +105°C.
The contacts are manufactured from copper alloy with a nickel underplate of at least 50 µin and a gold-plated mating surface. The black housing uses high-temperature Nylon 6T, also identified as PA6T, with a UL94 V-0 flammability classification.
This 2.54mm 20 pin SMT female header is suitable for board-to-board connections in industrial controllers, embedded systems, communication equipment, test instruments, development boards, power-control modules, and replaceable daughterboard assemblies.
