Key Parameters

Substitute Part Grouping Explanation

The substitute part 1950430000 qualifies as a direct equivalent based on the following critical parameters:

• Number of Positions: Both parts feature 14 positions, ensuring identical connector density and circuit capacity
• Pitch Specification: Both maintain 0.200" (5.08mm) pitch, guaranteeing mechanical and electrical compatibility with mating connectors
• Wire Entry Orientation: Both provide 270° free-hanging (in-line) configuration, maintaining identical installation geometry
• Electrical Ratings: The substitute part meets or exceeds the electrical performance envelope required for this application category
• Compliance Status: Both parts are RoHS Compliant with MSL 1 (Unlimited), satisfying regulatory and environmental requirements
• Manufacturer Consistency: Both are manufactured by Weidmüller, ensuring design continuity and quality standards

The primary distinction is product status: the original part is obsolete, while the substitute (1950430000) maintains active production status.
