Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1803180000 is determined by the following critical parameters:

• Number of Positions: 16 positions required
• Pitch Specification: 5.08mm (0.200") center-to-center spacing
• Plug Configuration: Female sockets with 180° wire entry orientation
• Termination Method: Screw-clamping mechanism
• Mounting Style: Free-hanging (in-line) installation
• Electrical Ratings: Current and voltage specifications per IEC and UL standards
• Wire Gauge Compatibility: 12-30 AWG (0.2-4mm²)
• Compliance Requirements: RoHS compliance and MSL rating

The identified substitute part 1944470000 satisfies all critical substitution parameters within the Omnimate BL series, maintaining mechanical and electrical compatibility with the original specification.

Engineering Selection Recommendations

The Weidmüller 1944470000 serves as the direct functional equivalent for the obsolete 1803180000. Selection of this substitute is supported by:

• Active Product Status: The 1944470000 maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Compliance Alignment: Both parts maintain identical RoHS compliance, REACH status, and regulatory classification (EAR99, HTSUS 8536.90.4000)
• Mechanical Compatibility: Identical pitch (5.08mm), position count (16), and 180° free-hanging orientation ensure direct mechanical substitution
• Electrical Equivalence: Both components operate within compatible electrical parameters for industrial terminal block applications
• Reliability Rating: Unlimited moisture sensitivity level (MSL 1) on both parts indicates suitability for standard industrial environments without special handling requirements

Frequently Asked Questions (FAQ)

Q: Can the 1944470000 directly replace the 1803180000 in existing installations?

A: Yes. Both parts share identical mechanical specifications (16 positions, 5.08mm pitch, 180° orientation) and mounting configuration (free-hanging in-line). The substitute maintains all compliance certifications and environmental ratings of the original part.

Q: What is the significance of the obsolete status of the 1803180000?

A: Obsolete status indicates the part is no longer manufactured by Weidmüller. The 1944470000 is an active product within the Omnimate BL series, providing continued availability and technical support for equivalent functionality.

Q: Are there differences in electrical ratings between these parts?

A: The 1944470000 specifies electrical ratings (IEC: 23A/400V; UL: 20A/300V) and wire gauge compatibility (12-30 AWG, 0.2-4mm²). These parameters define the operational envelope for the substitute and should be verified against system requirements.

Q: What is the significance of the screw-clamping termination method?

A: The 1944470000 uses screw-clamping yoke (tension sleeve) termination with M2.5 screws and 0.4-0.5 Nm torque specification. This is a standard industrial termination method ensuring secure wire retention and electrical contact.

Q: Are packaging considerations relevant to substitution?

A: The 1944470000 is supplied in bulk packaging. Original packaging specifications for the 1803180000 were not provided. Packaging format does not affect functional compatibility but may impact procurement and inventory management processes.

Q: Do both parts require special handling or storage conditions?

A: No. Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard industrial storage conditions are appropriate for both components.
