Engineering Selection Recommendations

The Weidmüller 1945090000 is the direct substitute for the obsolete 1893630000 based on the following engineering criteria:

Product Status: The 1945090000 is an active product in the Omnimate BL series, ensuring ongoing availability and manufacturing support. The 1893630000 is obsolete and no longer manufactured.

Regulatory Compliance: Both components maintain identical compliance certifications—RoHS Compliant, REACH Unaffected, and EAR99 export classification. This ensures no regulatory barriers to substitution.

Functional Compatibility: The 1945090000 provides identical mechanical and electrical interface specifications, including 5-position configuration, 5.08mm pitch, 180° wire entry orientation, and free-hanging mounting. These parameters define the physical and electrical compatibility required for direct substitution.

Electrical Performance: The 1945090000 meets or exceeds the electrical requirements with IEC ratings of 23A/400V and UL ratings of 20A/300V, supporting wire gauges from 12-30 AWG (0.2-4mm²).

For applications currently using the 1893630000, transition to the 1945090000 is recommended to ensure long-term component availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1945090000 directly replace the 1893630000 in existing designs?
