Weidmüller 7914400000 Terminal Block Connector Equivalent & Substitute Parts

Part Overview

The Weidmüller 7914400000 is a 2-position disconnect terminal block connector designed for wire gauges 10-26 AWG (0.5-6mm²). This component features screw termination, LED indicators, and fuse/removable plug disconnect functionality. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing system maintenance and new design implementations. Active equivalent models provide continued availability while maintaining functional compatibility within specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 7914400000 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Number of Positions: 2
• Number of Levels: 1
• Termination Style: Screw
• Disconnect Type: Fuse, Removable Plug
• Fuse Type: 5mm x 20mm
• Current Rating (IEC): 6.3 A
• Voltage Rating (IEC): 400V
• Material Flammability Rating: UL94 V-0
• Color: Beige

Allowable Variation Parameters:

• Wire Gauge Range (AWG): Substitute must accommodate the minimum wire gauge of the main part (10 AWG) or smaller
• Wire Gauge Range (mm²): Substitute must accommodate the minimum cross-section of the main part (0.5mm²) or smaller
• Terminal Width: May vary within mechanical compatibility constraints
• Voltage Rating (UL): May exceed the main part specification (300V)
• Stripping Length: May vary based on connector design
• Packaging: May differ from original specification

The substitute part Weidmüller 1763950000 meets all mandatory compatibility parameters. The wire gauge range difference (12-26 AWG versus 10-26 AWG) represents a narrower specification in the substitute, which is acceptable for applications not requiring the full 10 AWG capability.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1763950000 is a suitable substitute for the obsolete Weidmüller 7914400000 based on the following engineering criteria:

Compliance and Certification Alignment: Both parts maintain identical RoHS compliance status and UL94 V-0 flammability ratings, ensuring regulatory requirements are preserved across substitution.

Electrical Parameter Equivalence: Current and voltage ratings under IEC standards are identical (6.3 A, 400V). The substitute provides enhanced UL voltage rating (600V versus 300V), which represents an improvement in electrical capability without introducing incompatibility.

Functional Equivalence: Both components provide identical 2-position, single-level disconnect functionality with screw termination, fuse/removable plug disconnect type, and 5mm x 20mm fuse compatibility.

Product Status Advantage: The substitute part maintains active product status, ensuring continued availability and supply chain reliability compared to the obsolete main part.

Wire Gauge Consideration: The substitute accommodates wire gauges 12-26 AWG (0.5-4mm²) versus the main part's 10-26 AWG (0.5-6mm²). Applications requiring 10 AWG or 6mm² wire termination cannot use this substitute. Applications within the 12-26 AWG range are fully compatible.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 1763950000 directly replace the 7914400000 in all applications?

A: Direct replacement is possible for applications using wire gauges 12-26 AWG. Applications requiring 10 AWG wire termination capability must use the original part or identify alternative substitutes that support the full 10-26 AWG range.

Q: What are the key differences between these two parts?

A: The primary difference is wire gauge range. The 7914400000 supports 10-26 AWG, while the 1763950000 supports 12-26 AWG. The substitute provides higher UL voltage rating (600V versus 300V). All other electrical, mechanical, and functional parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the 7914400000 and 1763950000 are RoHS compliant and maintain identical UL94 V-0 flammability ratings.

Q: Does the substitute part have the same fuse compatibility?

A: Yes, both parts use 5mm x 20mm fuses and are fully compatible in this regard.

Q: What is the significance of the product status difference?

A: The 7914400000 is classified as obsolete, meaning it is no longer in active production. The 1763950000 maintains active status, ensuring continued availability from Weidmüller and authorized distributors.

Q: Can I use the 1763950000 in a system designed for 10 AWG wire?

A: No. The 1763950000 minimum wire gauge is 12 AWG. Systems requiring 10 AWG termination must use the original 7914400000 or identify alternative parts supporting the full 10-26 AWG range.

Q: Are the terminal widths compatible?

A: The terminal widths differ (6.1mm for 7914400000 versus 5.1mm for 1763950000). Both dimensions are within acceptable mechanical compatibility for the 2-position disconnect configuration.
