Please provide a part number which matches this -18 AWG Hook-Up Wire 16/30 White 10cm; 20°C ~ 125°C / 600V
I found the 391862WH005-ND as being similar.
I am not seeing a 10cm option.
The 391862WH005-ND would be 30.5meters.
If you do need it to be shorter please e-mail custom.orders@digikey.com
You would need to indicate the above item number and the length you would like.
