Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1764030000 is determined by the following critical parameters:

Core Functional Requirements:

• Number of positions: 2
• Number of levels: 1
• Disconnect type: Fuse and removable plug capability
• Fuse type: 5mm x 20mm
• LED indicator presence

Electrical Compatibility:

• Wire gauge overlap: Substitute must accommodate the 12-26 AWG range or a compatible subset
• Current rating: Substitute must meet or exceed 6.3 A (IEC) or 10 A (UL)
• Voltage rating: Substitute must meet or exceed 400 V (IEC) or 300 V (UL)

Physical and Material Compatibility:

• Terminal width and pitch must be mechanically compatible
• Termination style may vary (push-in spring vs. screw) provided electrical performance is maintained
• Flammability rating must meet UL94 V-0 or equivalent safety standard

The Phoenix Contact 3004142 qualifies as a substitute based on matching core functional requirements, exceeding electrical ratings, and maintaining fuse and LED functionality across the specified wire gauge range.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3004142 serves as a functional substitute for the obsolete Weidmüller 1764030000 based on the following engineering criteria:

Electrical Performance: The substitute meets or exceeds all electrical ratings specified for the main part. IEC and UL current and voltage ratings are equal to or higher, ensuring safe operation in applications designed for the original component.

Functional Equivalence: Both components provide 2-position disconnect terminal block functionality with fuse and LED indicator features. The 5mm x 20mm fuse type is identical, maintaining compatibility with existing fuse specifications.

Wire Gauge Compatibility: The Phoenix Contact 3004142 accommodates the full 12-26 AWG range of the original part, with extended capability down to 10 AWG, providing broader application flexibility.

Product Status and Availability: The substitute is classified as active and currently in production, ensuring long-term availability and supply chain continuity compared to the obsolete status of the original component.

Material and Safety Compliance: The substitute maintains UL94 flammability certification (V-2 rating) and REACH compliance, meeting regulatory requirements for electronic component applications.

Termination Consideration: The substitute employs screw termination rather than push-in spring termination. This represents a design difference requiring installation procedure adjustment but does not compromise electrical performance or safety ratings.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3004142 be used as a direct replacement for the Weidmüller 1764030000?

A: The Phoenix Contact 3004142 is functionally equivalent and meets all electrical and mechanical requirements. The primary difference is termination style (screw vs. push-in spring), which requires installation procedure adjustment but does not affect electrical performance or safety ratings.

Q: Are the electrical ratings of the substitute adequate for applications using the original part?

A: Yes. The Phoenix Contact 3004142 meets or exceeds all IEC and UL electrical ratings of the original component. Current ratings are 6.3 A (IEC) and 12 A (UL), and voltage ratings are 500 V (IEC) and 600 V (UL), all equal to or higher than the original specifications.

Q: What is the significance of the different flammability ratings (UL94 V-0 vs. V-2)?

A: Both ratings meet UL94 flammability standards for electronic components. The V-0 rating of the original part indicates higher flame resistance than the V-2 rating of the substitute. For applications with specific flammability requirements, this difference should be evaluated against application standards and regulatory requirements.

Q: Does the wire gauge range difference affect compatibility?

A: No. The substitute accommodates 10-26 AWG, which encompasses the original 12-26 AWG range. The extended lower range (10 AWG) provides additional flexibility for applications requiring smaller wire gauges.

Q: Are the fuse specifications identical between the two components?

A: Yes. Both components use 5mm x 20mm fuses, ensuring compatibility with existing fuse inventory and specifications.

Q: What is the impact of different disconnect mechanisms (removable plug vs. lever)?

A: Both mechanisms provide fuse and disconnect functionality. The removable plug design of the original part differs from the lever design of the substitute, but both achieve the same functional outcome of enabling safe circuit disconnection and fuse replacement.

Q: Is the Phoenix Contact 3004142 available in the same packaging as the original part?

A: The substitute is supplied in bulk packaging, whereas the original part packaging specification was not provided. Packaging format should be confirmed with the supplier based on application requirements and inventory management procedures.
