Weidmüller 1011100000 Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The Weidmüller 1011100000 is a 2-position disconnect terminal block connector rated for 12-22 AWG wire gauges. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part features screw termination, beige thermoplastic insulation with UL94 V-0 flammability rating, and compliance with REACH regulations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1011100000 is determined by the following critical parameters:

• Number of Positions and Levels: Both main and substitute parts must maintain 2 positions and 1 level configuration for mechanical compatibility.
• Termination Style: Screw termination is required to maintain installation methodology consistency.
• Terminal Width: Acceptable variance within 5.0-5.1mm range maintains housing and contact compatibility.
• Wire Gauge Compatibility: The substitute part must accommodate the 12-22 AWG range of the original part. Extended ranges (such as 12-30 AWG) are acceptable as they include the original specification.
• Electrical Ratings: Substitute parts must meet or exceed the IEC and UL current and voltage ratings of the original component.
• Material and Flammability: Identical insulation material (Thermoplastic, Wemid) and UL94 V-0 rating ensure equivalent safety and environmental performance.
• Color and Physical Form: Beige color and disconnect type configuration must be maintained for system consistency.

The Weidmüller 1855610000 qualifies as a direct substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1855610000 is the designated substitute for the obsolete 1011100000 based on the following engineering criteria:

Product Status and Availability: The 1011100000 is classified as obsolete, while the 1855610000 maintains active product status with confirmed inventory availability (1465 pcs in stock). This transition ensures continued supply chain viability.

Electrical Performance: The substitute part exceeds the current ratings of the original component (24 A IEC vs. 14 A IEC; 20 A UL vs. 10 A UL), providing enhanced electrical capacity. The IEC voltage rating of the substitute (500V) is lower than the original (800V); applications requiring the full 800V IEC rating must evaluate this parameter against system requirements.

Mechanical and Material Compatibility: Both parts maintain identical 2-position, 1-level configuration with screw termination. Terminal width variance (5.0mm to 5.1mm) remains within acceptable mechanical tolerance. Wire gauge range compatibility is confirmed, with the substitute accommodating the full 12-22 AWG specification of the original part.

Regulatory Compliance: Both components feature identical UL94 V-0 flammability rating and Thermoplastic Wemid insulation material. The substitute part carries RoHS compliance certification, meeting current regulatory requirements. Both parts maintain REACH unaffected status and identical ECCN/HTSUS classifications.

Packaging Consideration: The substitute is supplied in bulk packaging, whereas the original part packaging specification was not provided. Procurement processes should account for this packaging difference.

Frequently Asked Questions (FAQ)

Q: Can the 1855610000 directly replace the 1011100000 in existing applications?

A: The 1855610000 is mechanically and electrically compatible for applications operating within the substitute part's specifications. The primary consideration is the IEC voltage rating: if your application requires 800V IEC operation, the substitute's 500V IEC rating may not be suitable. For applications operating at or below 500V IEC, direct substitution is supported.

Q: What is the significance of the extended wire gauge range (12-30 AWG) in the substitute part?

A: The substitute part accommodates wire gauges from 12-30 AWG, which includes the original part's 12-22 AWG range. This extended capability does not affect compatibility with the original specification; it provides additional flexibility for future applications using smaller gauge wires.

Q: Are there mechanical differences between the two parts?

A: Terminal width differs slightly (5.0mm vs. 5.1mm), but this variance remains within acceptable mechanical tolerance for housing and contact compatibility. All other mechanical parameters, including position count, level configuration, and termination style, are identical.

Q: What is the impact of the substitute part's RoHS compliance?

A: RoHS compliance in the substitute part indicates adherence to current environmental and material restriction standards. This is advantageous for new designs and systems subject to modern regulatory requirements. The original part's RoHS status was not specified.

Q: How does the current rating difference affect substitution?

A: The substitute part's higher current ratings (24 A IEC and 20 A UL versus 14 A IEC and 10 A UL) indicate enhanced electrical capacity. This does not prevent substitution; the substitute can safely handle applications designed for the original part's current specifications.

Q: Is packaging a consideration for substitution?

A: The substitute part is supplied in bulk packaging. If your procurement or assembly process requires specific packaging formats, this difference should be evaluated with your supply chain management. The electrical and mechanical performance remains unchanged regardless of packaging.
