2.54mm Pitch Female Header PCB Connectors – 0.1 Inch Standard
2.54mm Pitch Female Header PCB Connectors – The Industry-Standard 0.1" Socket
Yoeruyo's 2.54mm pitch female header connectors are the definitive board-to-board and wire-to-board socket solution for electronics prototyping, development, and production. The 2.54mm (0.1 inch) pitch is the global industry standard for PCB headers, universally compatible with Arduino, Raspberry Pi, STM32, ESP32, and virtually every development board and single-board computer on the market. Our female headers are available in single-row, dual-row, right-angle, and SMD configurations across 2 to 40 positions.

Product Variants
- Single-row vertical TH – the most common configuration; 2 to 40 positions for standard pin header mating in development boards and production PCBs
- Dual-row vertical TH – 2×N configuration for higher pin density; widely used in JTAG, ISP, and expansion connector applications
- Right-angle TH – 90° orientation for edge-mount, panel-interface, and space-constrained board designs
- SMD (surface mount) – reflow-solderable female header for automated PCB assembly; low-profile and high-positional accuracy
- Long-body / extended socket – deeper socket depth for use with longer pin headers in stackable shield and HAT configurations
- Stackable female header – pass-through pin design allows multiple boards to be stacked (Arduino shield, Raspberry Pi HAT)
Application Scenarios
- Development boards & prototyping – Arduino Uno/Mega/Nano, Raspberry Pi, ESP32, STM32 Nucleo, and BeagleBone expansion headers
- Industrial control & automation – PLC I/O modules, relay boards, sensor interfaces, and HMI expansion connectors
- Test & measurement equipment – oscilloscope probes, logic analyzers, and bench instrument internal interconnects
- Consumer electronics – internal board-to-board connections in home appliances, routers, and set-top boxes
- Robotics & automation – motor driver boards, servo controllers, and sensor array interconnects
- Education & maker community – the universal standard for breadboard-compatible and shield-compatible PCB connectors worldwide

- ✅ Full range of configurations – single-row, dual-row, right-angle, SMD, stackable, and long-body from a single supplier
- ✅ Bulk & OEM supply – tube, tray, and tape-and-reel packaging for production environments; flexible MOQ
- ✅ RoHS & REACH compliant – halogen-free materials meet EU and global environmental standards
Buying Guide – Selecting the Right 2.54mm Female Header
- Pin count – match to your mating pin header; standard counts are 2, 3, 4, 5, 6, 8, 10, 12, 14, 16, 20, 24, 26, 34, 40
- Single vs dual row – single-row for most general-purpose applications; dual-row for JTAG, ISP, and high-density expansion connectors
- Vertical vs right-angle – vertical for standard board-to-board mating; right-angle for edge connectors and panel-mount interfaces
- Stackable vs standard – stackable headers allow shield/HAT stacking; standard headers provide a lower profile and more secure termination
- Tin vs gold plating – tin for cost-effective production use; gold for high-cycle, high-reliability, or harsh-environment applications
Frequently Asked Questions
Are these female headers compatible with standard 2.54mm pin headers?
Yes. Yoeruyo 2.54mm female headers are fully compatible with industry-standard 2.54mm (0.1") pitch pin headers from all major manufacturers including Amphenol, Molex, TE Connectivity, and equivalent generic headers.
Can I use these with Arduino and Raspberry Pi?
Yes. The 2.54mm pitch is the standard used on Arduino Uno, Mega, Nano, Raspberry Pi GPIO headers, and virtually all compatible shields and HATs. Our stackable female headers are specifically designed for shield and HAT stacking applications.
What is the difference between tin and gold plated contacts?
Tin-plated contacts are cost-effective and suitable for most production applications with moderate mating cycles. Gold-plated contacts offer lower contact resistance, better corrosion resistance, and higher mating cycle ratings — recommended for high-reliability, high-cycle, or harsh-environment applications.
Can the female header strip be cut to a custom pin count?
Some through-hole female header strips can be cut, but cutting may damage end contacts. For production use, order the exact pin count required. Contact us for custom-length options and minimum order quantities.
Do you offer bulk pricing for PCB assembly houses?
Yes. Yoeruyo offers tiered pricing for orders of 1,000 units or more. Tape-and-reel packaging is available for SMD variants. Contact us for volume quotations and consignment supply arrangements.
