SUMMARY

This discussion addresses the challenge of adapting a PCB designed for 0.150" pitch header pins to accommodate a component with 0.1" pin spacing. Users suggest two primary solutions: using wire wrap sockets for small quantities or creating a custom adapter using perforated veroboard for larger quantities. The veroboard method involves cutting a rectangle into triangles to form a right angle triangle adapter, allowing for a diagonal pitch conversion. The specific configuration discussed involves a component with two rows of 8 pins.

PREREQUISITES
  • Understanding of PCB design and layout
  • Familiarity with header pin specifications
  • Knowledge of wire wrap sockets and their applications
  • Experience with veroboard and basic circuit prototyping
NEXT STEPS
  • Research the use of wire wrap sockets for PCB adaptations
  • Learn how to create custom adapters using perforated veroboard
  • Explore techniques for cutting and shaping veroboard for specific pin configurations
  • Investigate other methods for converting pin pitches in PCB designs
USEFUL FOR

Electronics engineers, PCB designers, and hobbyists looking to adapt components with differing pin spacings efficiently.

I made a mistake on a PCB I designed, and have a set of through holes that are spaced 0.150" apart, when the component I want to put into it has a pin-pin spacing of 0.1". Does anyone know of a simple adapter that could go between these two sizes? I'm looking to avoid the time consuming task of running 16 individual wires.

I looked around on Digkey, and couldn't see anything for this.

That is not a common transform. How many rows and pins on the device.
For small quantities: Wire wrap sockets are still available. Splay the pins.
For large quantities: Make a small adapter for the IC to the PCB.
 
Alternatively; Cut a rectangle of perforated veroboard with 0.1” pitch strips.
The number of strips width will fit the 0.1” IC, the length of the rectangle being 1.118 times longer.
Cut the rectangle into two triangles and you have an 0.1” to 0.15” diagonal pitch converter.
The right angle triangle adapter will naturally have an angle of 42°, being the answer to the universe and everything.
You can mount the IC at that angle off the PCB or rotate it by that angle on the plane of the PCB.

Thanks for the sugestions. It is two rows of 8 pins. I like your veroboard trick.
