Engineering Selection Recommendations

The Weidmüller 1944260000 is the direct active equivalent for the obsolete 1803000000. Selection of the substitute part is based on:

Product lifecycle status: The 1803000000 is obsolete; 1944260000 is active and maintains long-term availability
Mechanical and electrical compatibility: Both parts share identical mechanical interfaces, pitch, position count, and termination methodology, ensuring direct replacement in existing connector systems
Enhanced electrical performance: The substitute part provides higher current ratings (23A IEC / 20A UL vs. 19A IEC / 15A UL) and expanded wire gauge acceptance (12-30 AWG vs. 12-26 AWG), offering improved flexibility for wire selection without compromising safety
Regulatory compliance: Both parts maintain identical REACH and ECCN classifications, with the substitute part additionally certified as RoHS Compliant
Thermal and environmental equivalence: Identical operating temperature range (-50°C ~ 100°C) and flammability rating (UL94 V-0) ensure performance parity across environmental conditions

Frequently Asked Questions (FAQ)

Q: Can 1944260000 directly replace 1803000000 in existing assemblies?

A: Yes. Both parts maintain identical 19-position configuration at 0.200" (5.08mm) pitch, 180° plug wire entry, free-hanging mounting, and screw-clamping termination. Mechanical and electrical interfaces are fully compatible.

Q: What are the key differences between these parts?

A: The substitute part 1944260000 offers higher current ratings (23A IEC vs. 19A IEC; 20A UL vs. 15A UL), expanded wire gauge range (12-30 AWG vs. 12-26 AWG; 0.2-4mm² vs. 0.2-2.5mm²), and active product status. Insulation height differs slightly (0.632" vs. 0.598"), but this does not affect mechanical compatibility.

Q: Are there packaging differences?

A: The main part 1803000000 is listed with unspecified packaging; the substitute 1944260000 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both parts are REACH Unaffected and classified as EAR99. The substitute part 1944260000 additionally carries RoHS Compliance certification.

Q: Can I use 1944260000 in applications with wire gauges smaller than 12 AWG?

A: No. Both parts accept wire gauges from 12 AWG minimum. For smaller gauge requirements, alternative terminal block designs must be evaluated.

Q: What is the impact of the higher current rating on system design?

A: The substitute part's higher current rating (23A IEC / 20A UL) provides design margin and does not require system modifications. Existing designs rated for the original part's current specifications remain valid.
