TE Connectivity offers a huge range of simple rectangular connectors and headers, including 9-146253-0. However, when searching for that part number on the DigiKey website, you’ll run across a collection of products with the same part number ended by a two-digit suffix ranging from -01 to -39, like so: Headers With Suffixes. What do all these suffixes mean, and which part is the real 9-146253-0?
All of these are the real product, but everything with a suffix is a DigiKey value-added modification of the original device. 9-146253-0 is an 80-position, 40-row header; the suffixed versions are connectors we cut down from this master product to a smaller position count to fit your precise requirement.
