hanxia HX PH254-01-04-Z-L11.5 straight pin header

Product FAQ

• 1. Is This Pin Header Compatible With Standard Breadboards and Dupont Wires?
  Yes, absolutely. This pin header features a standard pitch of 2.54mm (0.1 inch), making it fully compatible with standard breadboards, prototyping boards, and standard female Dupont wire connectors.
• 2. What Can I Use as a Replacement if This 4-Pin Header Is Out of Stock?
  If this specific 4-pin model is unavailable, you can easily purchase a longer 1x40P straight pin header with the same 2.54mm pitch and snap or cut it down to a 4-pin length using a pair of pliers.
• 3. What Are the Common Application Scenarios for This Straight Pin Header?
  This component is widely used for creating pluggable board-to-board or wire-to-board connections. Common scenarios include exposing microcontroller pins (like Arduino or Raspberry Pi GPIOs), connecting sensor modules, and attaching debugging interfaces (such as UART, I2C, or SPI) to PCBs.
• 4. What Are the Maximum Current and Voltage Ratings Supported Through This Component?
  This pin header has a rated current of 3A and can handle a maximum voltage rating of up to 1kV. It features brass contacts with gold plating for reliable electrical conductivity and resistance to oxidation.
• 5. How Do I Properly Solder and Install This Through-Hole Header onto a PCB?
  Insert the shorter end (the 3mm end connection pin) into the through-holes of your PCB from the top side. Flip the board over and apply solder to each pin on the bottom side, ensuring the header remains perfectly perpendicular to the board during the process. The longer 6mm side will remain exposed to mate with female connectors.
