20X2 Female Berg Strip Throughhole Header (2.54mm Pitch)

Description The 20x2 Double Row Female Header (commonly known as a Berg Strip) is a fundamental electronic component used for creating secure, pluggable board-to-board or wire-to-board connections. Utilizing the industry-standard 2.54mm (0.1") pitch, this 40-pin double-row socket is perfectly sized to mate with standard 2.54mm male headers, allowing you to easily attach and remove custom shields, modules, or ribbon cables from your main circuit board. Available at Tomson Electronics, this specific header features a traditional Through-Hole (T.H) design. The long metal pins pass completely through the printed circuit board (PCB) to be soldered on the opposite side, providing excellent mechanical strength and durability against repeated insertions and removals. With its 20x2 configuration, it is most famously used as the GPIO expansion header on Raspberry Pi single-board computers, making it an absolute necessity for building custom Pi HATs and breakout boards.

Specifications Row Configuration: 20x2 (Double Row) Total Number of Pins: 40 Pin Pitch (Spacing): 2.54 mm (0.1 inches) Gender: Female (Socket) Mounting Type: Through-Hole (THT / T.H) Orientation: Straight (Vertical) Contact Material: Phosphor Bronze / Copper Alloy Insulator Material: High-Temperature Thermoplastic (Black) Applications Raspberry Pi Projects: Soldering onto custom printed circuit boards to create your own Raspberry Pi HATs (Hardware Attached on Top) that plug directly into the Pi's 40-pin GPIO. Robust PCB Interconnects: Serving as strong, through-hole board-to-board connectors in DIY electronics, robotics, and custom embedded systems. Wire-to-Board Terminations: Providing a secure plug-in point for 2.54mm IDC ribbon cables or individual jumper wires. Frequently Asked Questions (FAQ) Q: Can I easily cut this double-row strip into smaller pieces? A: Unlike single-row breakaway male headers, cutting double-row female headers cleanly can be tricky. Slicing through the plastic often destroys the contact pins directly on the cut line. If you must cut it to a smaller size (like a 10x2), we recommend using a sharp craft knife or fine saw, intentionally sacrificing one row of pins, and then pulling out the scrap metal bits and sanding the edge flat. Q: Is this the correct header for a Raspberry Pi? A: Yes! The standard Raspberry Pi (models 1 B+, 2, 3, 4, and 5) uses a 20x2 male header with a 2.54mm pitch. This female socket is the exact counterpart needed if you are designing a board to plug into the top of the Pi. Q: Will this fit on a standard solderless breadboard? A: While the 2.54mm pitch matches a breadboard, you generally cannot plug a double-row header into the center of a standard breadboard without shorting the two rows together, because breadboard contact strips run horizontally across the center divide.
