Key Parameters

Substitute Part Grouping Explanation

The substitute part DF11CZ-18DP-2V(27) is designated as the manufacturer-recommended replacement for the obsolete DF11Z-18DP-2V(21). The substitution is based on the following critical parameters:

• Base product family alignment: Both parts belong to the DF11 series manufactured by Hirose Electric Co Ltd
• Connector configuration: 18-position, 2-row rectangular connector
• Pitch specification: 0.079" (2.00mm) mating pitch maintained across both parts
• Row spacing: 0.079" (2.00mm) consistent between main and substitute part
• Electrical ratings: Both support 2A current rating and 250V voltage rating
• Mounting compatibility: Surface mount termination with solder attachment

The transition from DF11Z to DF11C variant represents a product line evolution within the same connector family, with the substitute part offering active product status and improved availability.
