The 0.100″ (2.54 mm) 2×2-Pin Straight Female Header is a compact double-row, 4-pin socket strip designed to mate with standard 0.1″ pitch male headers. Its small 2×2 footprint is ideal for simple power or signal connections that require a keyed dual-row arrangement.
Common uses include jumper block interfaces, small power connectors, and compact board-to-board links where a minimal pin count is needed in a dual-row format.
Key Features
- 0.1″ (2.54 mm) Pitch – Industry-standard spacing compatible with breadboards and perfboard
- Straight Orientation – Mounts perpendicular to the PCB for standard vertical connections
- 2×2-Pin Configuration – Double-row, 4-position socket
- Through-Hole Mounting – Solders directly to standard PCBs
Ideal For
- Jumper block and configuration interfaces
- Compact power connections
- Board-to-board links
- Prototyping and custom interconnects
Package Contents
- 1× 0.100″ (2.54 mm) 2×2-Pin Straight Female Header
Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- through-hole
- A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
