2.54mm Pin Headers and Sockets

2.54mm pitch spacing pin headers and sockets are are available in through hole or surface mount in single, double and triple row. Straight, right angle and U shaped configurations allow a wide variety of design options.

High temperature 2.54mm (.1") pitch connectors withstands high temperature solder processes up to 280°C (IR Reflow) with LCP or Nylon 6T insulators.

Operating temperature is -40°C to + 105°C with a current rating of 3 amps.

  • SMD and Through Hole
  • Headers offer customer specifiable pin lengths and spacer heights
  • Elevated stacking headers and sockets
  • Choice of male pin and female contact material and plating
  • Female headers available with a choice of insulator height
Pin headers and sockets are available in tape & reel, tube and plastic box packaging. For automatic pick and place processing, we offer caps for headers and film for sockets, these options are available in tape & reel and tube.

All 2.54mm pin headers and sockets are fully RoHS and Reach compliant.
Pitch

Distance between connector pin centrelines. For dual row products pitch defines distance between both pins and rows. Note 0.8 x 1.2mm (0.31” x .047”) is the exception to this rule.

Gender

Male headers with exposed pins and female sockets with insulated non-exposed contacts.

Number Of Rows

Defines PCB connector number of rows. GCT offer single in line (SIL), dual in line (DIL), triple in line (three rows) and quad in line (four rows) options.

Mount Type

Termination method of soldering connector onto PCB.

PCB Orientation

Defines the orientation which a connector sits on the PCB. Vertical (straight) is 90° to the PCB, right angle (horizontal) is 180° to the PCB. Use the appropriate mating connector pairs for parallel, co-planar and right angle PCB mating configuration.

Socket Entry Type

Searches female connectors only and displays whether header pins may enter from above (top entry), from below with appropriate holes in PCB (bottom entry) or from both above and below (dual entry). See drawings for details of PCB layouts required for bottom entry connector mating.

Socket Contact Type

Socket contact type", "Searches female connectors only. Two contact types: ‘Leaf Spring’ and ‘Tuning Fork’, both offer two points of contact with mating header pins. ‘Tuning Fork’ is the lower cost option, with higher insertion and extraction force, suitable only for top entry applications. ‘Leaf Spring’ is lower force contact and suitable for top, bottom & dual entry applications. For higher number of mating cycles choose ‘Leaf Spring’.

Locating Peg

Plastic locating pegs to hold the connector in place during solder process and may provide extra strength post soldering. Also known as plastic post.

Profile

The profile of connectors above the PCB. Vertical connectors denote the stacking profile in parallel PCB applications, right angle connectors denotes height above the PCB.

Header Pin Size

Displays the size of the header square pin/post, as connector pitch reduces sq. post size reduces too, one reason for lower current carrying capability of smaller pitch PCB connectors. Note: Two options in 1.27mm (.050”) pitch. Female sockets clearly state which header square pin size they mate with.

  • 0.30mm
  • 0.30mm x 0.42mm
  • 0.40mm
  • 0.46mm
  • 0.50mm
  • 0.64mm (6)
  • 1.14mm
  • N/A
Elevated

Products which achieve a greater space between PCB’s, normally used in parallel PCB stacking applications to achieve a desired height. Elevated headers normally have two insulators, while elevated sockets use an insulator block and modular insulator extenders.

Insulator Colour

Standard board to board connector range is black, white insulators used for White Lite range for Solid State Lighting (SSL) applications.
