Compliant Pin Technology

Delphi Connection Systems

Delphi, a worldwide leader in automotive connection systems, has integrated Compliant Pin Technology into several of its automotive connection products. This advanced technology is utilized in device connectors and integrated connector/module housings to press-fit solderless electrical contacts onto printed circuit board (PCB) assemblies. When a compliant pin is inserted into a plated-through-hole (PTH) of a PCB, it creates a reliable, gas-tight contact.


  • Environmental compliance—easily adaptable to lead-free construction
  • No separate soldering process necessary
  • Low thermal stress—no heat to affect other board components
  • Suitable for multilayer and double-sided PCBs
  • Reliable gas-tight connection—no corrosion
  • Reliable performance in vibration and shock
  • Low PTH distortion and damage
  • Connector can use standard plastic material
  • Connectors and contacts are easier to repair than soldered pins
  • Available in two circuit board hole sizes for application flexibility
    • 1.0 mm
    • 1.2 mm


  • United States Council for Automotive Research (USCAR) headers
  • Engine and transmission control modules
  • Airbag control modules and ABS modules
  • Key fobs, impact sensors, and passive occupant detection systems (PODS)
  • Bussed electrical centers (BECs) and bus bars
  • Single pins
