Parameter Comparison

Engineering Selection Recommendations

The substitute part 1944490000 is the direct equivalent for the obsolete 1803200000 based on the following engineering criteria:

Product Status Transition: The original part carries obsolete status, limiting long-term availability and manufacturer support. The substitute maintains active product status, ensuring continued supply chain access and technical support from Weidmüller.

Compliance Alignment: Both parts carry identical regulatory classifications (REACH Unaffected, ECCN EAR99, HTSUS 8536.90.4000) and moisture sensitivity ratings (MSL 1), confirming regulatory equivalence for industrial applications.

Mechanical and Electrical Compatibility: The 18-position configuration, 5.08mm pitch, and 180° wire entry orientation are preserved across both parts, enabling direct mechanical substitution in existing connector assemblies and PCB layouts.

Enhanced Specifications: The substitute part provides additional documented specifications including IEC/UL current and voltage ratings (23A/400V IEC; 20A/300V UL), operating temperature range (-50°C to 100°C), and material certifications (UL94 V-0, RoHS Compliant) that support broader application compatibility.

Frequently Asked Questions (FAQ)

Q: Can part 1944490000 be used as a direct replacement for 1803200000 in existing assemblies?

A: Yes. Both parts share identical critical parameters: 18 positions, 5.08mm pitch, 180° wire entry orientation, and black color. The mechanical and electrical interfaces are fully compatible.

Q: What is the primary reason for substitution?

A: The original part 1803200000 is classified as obsolete. The substitute 1944490000 is an active product with continued manufacturer support and availability.

Q: Are there compliance differences between the two parts?

A: No. Both parts carry identical REACH Unaffected status, ECCN EAR99 classification, and MSL 1 rating. Regulatory compliance is equivalent.

Q: Does the substitute part provide additional technical specifications?

A: Yes. Part 1944490000 includes documented electrical ratings (23A IEC / 20A UL), operating temperature range (-50°C to 100°C), material certifications (UL94 V-0), and RoHS compliance status. These specifications support broader application verification but do not affect substitution compatibility.

Q: What is the packaging difference?

A: The original part packaging is not specified. The substitute is supplied in bulk packaging, which is standard for terminal block components.

Q: Are there any installation or termination differences?

A: Both parts use screw-based termination. The substitute specifies M2.5 screw size with 0.4-0.5 Nm torque specification and 7mm wire strip length, providing clear installation guidance for field assembly.
