Hirose has changed the manufacturing facility of the DF11 Series (SMT Type). Because of the production line move, there is now a slight change in shape to the reinforcement fittings. Although there is a slight difference in the shape, the products' performance remains unchanged. Production with these changes began August 2011. For further questions, please contact a Mouser Technical Support Representative.
