Key Parameters

Substitute Part Grouping Explanation

The substitute part 1950550000 qualifies as a functional equivalent based on the following critical parameters:

• Pitch Specification: Both parts operate at 0.200" (5.08mm) pitch, ensuring mechanical compatibility with existing PCB layouts and mating connectors
• Connector Orientation: Both feature 270° free hanging (in-line) configuration, maintaining identical mounting and wire entry geometry
• Position Count: Both are 2-position terminal blocks, supporting the same circuit density requirements
• Electrical Ratings: The substitute meets or exceeds the electrical performance envelope with IEC ratings of 23A at 400V and UL ratings of 20A at 300V
• Compliance Profile: Both parts maintain RoHS Compliance, MSL 1 (Unlimited), and REACH Unaffected status, ensuring regulatory continuity
• Termination Method: Both utilize screw-clamping technology with compatible wire gauge ranges (12-30 AWG / 0.2-4mm²)

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1950550000 is the designated substitute for the obsolete 1894620000 based on the following engineering criteria:

Product Status Alignment: The substitute maintains Active product status with ongoing manufacturer support, ensuring long-term availability and technical documentation access. The original part's Obsolete classification creates supply chain risk and limits future procurement options.

Regulatory Compliance Continuity: Both parts maintain identical RoHS Compliance, MSL 1 (Unlimited), and REACH Unaffected certifications, ensuring no regulatory reclassification or compliance documentation changes are required during substitution.

Mechanical and Electrical Compatibility: The substitute preserves all critical mechanical parameters—5.08mm pitch, 2-position configuration, 270° orientation, and screw-clamping termination—enabling direct replacement without PCB redesign or connector interface modifications. The substitute's specified electrical ratings (23A IEC / 20A UL) provide adequate performance margin for applications previously served by the original part.

Manufacturing Continuity: Both components are manufactured by Weidmüller, maintaining consistent quality standards, material specifications (PBT housing, copper alloy contacts), and screw torque requirements (0.4-0.5 Nm).

Frequently Asked Questions (FAQ)

Q: Can the 1950550000 directly replace the 1894620000 in existing designs?

A: Yes. Both parts share identical pitch (5.08mm), position count (2), orientation (270° free hanging), and termination method (screw-clamping). No PCB layout or connector interface modifications are required.

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

A: The substitute 1950550000 specifies electrical ratings of 23A at 400V (IEC) and 20A at 300V (UL). The original part's electrical specifications are not provided in the available documentation. The substitute's ratings establish a defined performance envelope suitable for terminal block applications in this category.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are RoHS Compliant, MSL 1 (Unlimited), and REACH Unaffected. No compliance documentation changes are necessary during substitution.

Q: What is the significance of the substitute's Active product status?

A: Active status indicates ongoing manufacturer production, technical support availability, and long-term supply chain stability. The original part's Obsolete classification means production has ceased and future availability cannot be guaranteed.

Q: Are there packaging differences between these parts?

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

Q: What wire gauges are compatible with both parts?

A: Both parts accept 12-30 AWG (0.2-4mm²) wire gauges, maintaining identical termination compatibility.
