Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1741890000 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the original specifications (IEC: 16.5A @ 400V; UL: 10A @ 300V)
• Mechanical Compatibility: Identical pitch (0.200" / 5.08mm), number of positions (4), plug wire entry angle (225°), and mounting type (free hanging in-line)
• Termination Compatibility: Screw-clamping termination style with M2.5 screw size
• Wire Gauge Compatibility: Wire gauge range must accommodate the original specification (12-26 AWG / 0.2-2.5mm²)
• Environmental Ratings: Operating temperature range and flammability rating (UL94 V-0)
• Contact Material: Copper alloy with tin mating finish

The substitute part 1946580000 meets all critical substitution criteria while offering enhanced electrical ratings and expanded wire gauge compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1946580000 is a direct substitute for the obsolete 1741890000 terminal block plug. The substitute part maintains identical mechanical and electrical interface specifications while offering enhanced electrical performance and expanded wire gauge compatibility.

The 1946580000 carries active product status, ensuring long-term availability and supply chain continuity. Both parts comply with identical regulatory standards (UL94 V-0 flammability rating, REACH unaffected, EAR99 export classification). The substitute part includes RoHS compliance certification and improved ingress protection (IP20), providing additional environmental protection in industrial applications.

For applications currently using the 1741890000, direct substitution with the 1946580000 is supported without design modification. The enhanced current ratings (17.5A IEC / 15A UL) and expanded wire gauge range (12-30 AWG / 0.2-4mm²) provide additional design margin and flexibility for future applications.

Frequently Asked Questions (FAQ)

Q: Can the 1946580000 directly replace the 1741890000 in existing installations?

A: Yes. The 1946580000 maintains identical pitch (5.08mm), position count (4), wire entry angle (225°), mounting type (free hanging in-line), and termination style (screw-clamping). All mechanical and electrical interfaces are compatible.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active), electrical ratings (enhanced in the substitute), and wire gauge range (expanded from 12-26 AWG to 12-30 AWG). The substitute also includes IP20 ingress protection and RoHS compliance.

Q: Are the electrical ratings of the 1946580000 backward compatible with the 1741890000 specifications?

A: Yes. The 1946580000 exceeds the original electrical specifications (17.5A IEC vs. 16.5A IEC; 15A UL vs. 10A UL) while maintaining identical voltage ratings (400V IEC / 300V UL). Applications designed for the original part operate within the substitute's electrical envelope.

Q: What is the wire gauge compatibility between these parts?

A: The 1741890000 accepts 12-26 AWG (0.2-2.5mm²). The 1946580000 accepts 12-30 AWG (0.2-4mm²). The substitute accommodates all wire gauges supported by the original part and extends compatibility to larger gauges (28-30 AWG / 3-4mm²).

Q: Are there packaging differences between these parts?

A: The 1741890000 is supplied in standard packaging. The 1946580000 is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: What compliance certifications apply to both parts?

A: Both parts carry UL94 V-0 flammability rating, REACH unaffected status, and EAR99 export classification. The 1946580000 additionally includes RoHS compliance certification.
