Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1889050000 is based on the following critical parameters:

• Pitch: 0.200" (5.08mm) — determines mechanical and electrical compatibility with mating connectors
• Number of Positions: 11 positions — ensures equivalent circuit density and connection capacity
• Connector Type: Terminal Block Plug with Female Sockets — maintains functional interface compatibility
• Plug Wire Entry Orientation: 90° — ensures proper spatial and installation compatibility
• Electrical Ratings: Current and voltage specifications must meet or exceed application requirements
• Termination Style: Screw-based clamping mechanisms — ensures equivalent wire retention and reliability
• Compliance Standards: RoHS and REACH compliance — maintains regulatory alignment with original component

The substitute part 1949890000 satisfies all critical substitution criteria within the Omnimate BL series, providing direct functional equivalence for the obsolete 1889050000.
