2.54mm Pitch Pin Header PCB Connectors – 0.1 Inch Standard
2.54mm Pitch Pin Header PCB Connectors – The Universal 0.1" Male Header Standard
Yoeruyo's 2.54mm pitch pin headers are the foundational male connector for PCB-to-PCB, wire-to-board, and board-to-panel interconnections across the global electronics industry. The 2.54mm (0.1 inch) pitch is the universally adopted standard for development boards, industrial control systems, test equipment, and consumer electronics. Our pin headers are available in single-row, dual-row, right-angle, and SMD configurations from 2 to 40 positions, with straight and kinked (retention) pin options.

Product Variants
- Single-row vertical TH – the most widely used configuration; breakable strip from 1 to 40 positions for flexible pin count selection
- Dual-row vertical TH – 2×N configuration for JTAG, ISP, IDC ribbon cable, and high-density expansion connectors
- Right-angle TH – 90° pin orientation for edge-mount, panel-interface, and space-constrained PCB designs
- SMD (surface mount) – reflow-solderable pin header for automated PCB assembly; high positional accuracy
- Short-pin / long-pin variants – custom above-insulator pin lengths for specific mated height requirements in stacked board designs
- Kinked (retention) pin – bent pin below insulator for press-fit retention during soldering without fixtures
Application Scenarios
- Development boards & prototyping – Arduino, Raspberry Pi GPIO, ESP32, STM32, and all breadboard-compatible single-board computers
- Industrial control & PLC systems – I/O expansion modules, relay boards, sensor interfaces, and HMI connectors
- Test & measurement – oscilloscope, logic analyzer, and bench instrument internal board interconnects and probe connections
- Consumer electronics – internal board-to-board connections in routers, set-top boxes, home appliances, and smart home devices
- Robotics & drones – motor driver, ESC, servo, and sensor array connections on flight controller and robot controller boards
- IDC ribbon cable assemblies – dual-row 2.54mm pin headers as the PCB-side termination for flat ribbon cable connectors
Why Choose Yoeruyo 2.54mm Pin Headers
- ✅ Universal compatibility – 2.54mm pitch is the global standard; mates with female headers from all major manufacturers
- ✅ Breakable strip design – single-row strips can be broken to any pin count from 1 to 40 without tools
- ✅ Tin & gold plating options – tin for cost-effective production; gold for high-reliability and high-cycle applications
- ✅ Full configuration range – single-row, dual-row, right-angle, SMD, short-pin, long-pin, and kinked variants from a single supplier
- ✅ RoHS & REACH compliant – halogen-free materials meet EU and global environmental standards
Buying Guide – Selecting the Right 2.54mm Pin Header
- Pin count – single-row strips are breakable; order a 40-pin strip and break to size, or order exact counts for production efficiency
- Single vs dual row – single-row for general-purpose GPIO and expansion; dual-row for JTAG, ISP, IDC ribbon cable, and high-density connectors
- Vertical vs right-angle – vertical for standard board-to-board mating; right-angle for edge connectors and panel-mount interfaces
- Pin length – standard 11.5mm total length suits most applications; short-pin for low-profile designs; long-pin for stacked board clearance
- Tin vs gold plating – tin for cost-effective production; gold for high-cycle, high-reliability, or corrosive-environment applications
Frequently Asked Questions
Are these pin headers compatible with standard 2.54mm female headers?
Yes. Yoeruyo 2.54mm pin headers are fully compatible with industry-standard 2.54mm female headers from all major manufacturers including Amphenol, Molex, TE Connectivity, and equivalent generic headers.
Can I break the single-row strip to a custom pin count?
Yes. Single-row 2.54mm pin header strips are designed to be broken at any position. Score the insulator between the desired pins and snap cleanly. This is standard practice for prototyping and small-batch production.
What is the standard pin length for 2.54mm headers?
The most common configuration has a total pin length of 11.5mm: approximately 6mm above the insulator (for mating with a female header) and 3mm below (for PCB through-hole soldering). Short-pin (6mm total) and long-pin variants are available for specific stack height requirements.
Are SMD pin headers suitable for reflow soldering?
Yes. SMD 2.54mm pin headers are designed for reflow soldering in automated PCB assembly. The insulator material is rated for standard reflow temperatures (peak 260°C for lead-free processes).
Do you offer bulk pricing for PCB assembly houses and OEM manufacturers?
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 for production lines.
