Key Parameters

Substitute Part Grouping Explanation

The substitute part 1947740000 qualifies as a direct functional equivalent based on the following critical parameters:

• Position Count & Pitch: Both parts feature 23 positions at 0.200" (5.08mm) spacing, ensuring mechanical and electrical interchangeability in connector mating applications
• Wire Entry Orientation: Both maintain 270° free-hanging (in-line) configuration for identical installation geometry
• Termination Method: Both employ screw-clamping yoke (tension sleeve) termination, supporting the same wire gauges (12-30 AWG / 0.2-4mm²)
• Electrical Ratings: The substitute meets or exceeds the original specifications with 23A (IEC) and 400V (IEC) ratings
• Material & Environmental Compliance: Both use PBT housing with copper alloy contacts, maintaining identical thermal performance (-50°C to +100°C) and regulatory compliance (RoHS, REACH)
• Manufacturer Consistency: Both are Weidmüller products, ensuring design continuity and quality standards

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1947740000 is the appropriate selection for applications currently using or requiring the Weidmüller 1894000000. The original part's obsolete status necessitates transition to an active product line. The substitute maintains full electrical and mechanical compatibility across all critical parameters while offering the advantage of active manufacturing status and current supply chain availability.
