Difference between Hirose U.FL-R-SMT(10) and U.FL-R-SMT-1(10)

Welcome to the Forum thinesh.ravi
I searched on the forum for suffix info on the Hirose connector.
I found the answer here: Hirose U.FL series Receptacles - Suffix
The -1 is an internal callout by Hirose for the location it was manufactured.
So there is no difference between the parts, just where they were made.
