Weidmüller 1702370000 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1702370000 is a 5-position terminal block plug with female sockets, 7.5mm pitch, and 270° free-hanging (in-line) configuration. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The plug accommodates wire gauges from 12-26 AWG (0.08-2.5mm²) with screw-clamping termination and operates across -20°C to 100°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 1702370000 is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: 5-position plug with female sockets, 7.5mm pitch, 270° wire entry, free-hanging mounting
• Electrical Ratings: Minimum 15 A (UL) and 300 V (UL) capability
• Wire Accommodation: Support for 12-26 AWG wire gauge range (0.08-2.5mm²)
• Termination Method: Screw-based clamping mechanism
• Material Compliance: UL94 V-0 flammability rating
• Contact Finish: Tin plating for mating surfaces

The TE Connectivity AMP Connectors part number 284042-5 (Buchanan series) satisfies these core substitution criteria while maintaining functional equivalence for the specified application parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 284042-5 qualifies as a functional equivalent for the obsolete Weidmüller 1702370000 based on matching electrical ratings, connector geometry, and core mechanical specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Key considerations for selection:

• Electrical Compatibility: Both parts meet 15 A (UL) and 300 V (UL) requirements, supporting identical current and voltage applications.
• Mechanical Interface: Identical 7.5mm pitch, 5-position configuration, and 270° wire entry ensure physical compatibility with mating connectors designed for the original part.
• Wire Accommodation: The TE part supports an extended wire gauge range (12-30 AWG / 0.05-3mm²), providing broader application flexibility while maintaining compatibility with the original 12-26 AWG specification.
• Operating Environment: The TE part's extended temperature range (-40°C to 110°C) exceeds the original specification (-20°C to 100°C), suitable for applications requiring wider thermal tolerance.
• Compliance: Both parts carry UL94 V-0 flammability certification and tin contact finish, meeting identical material and safety standards.
• Termination Mechanism: While both employ screw-based clamping, the TE part uses a rising cage clamp versus the original tension sleeve design. Verify screw torque specifications (TE: 0.79 Nm vs. original: 0.4-0.5 Nm) and mechanical fit within the application enclosure.
• Screw Specification: The TE part uses M3 screws compared to M2.5 on the original. Confirm that application hardware and mounting provisions accommodate this difference.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 284042-5 directly replace the Weidmüller 1702370000 in existing installations?

A: Yes, for applications where the connector mates with standard 7.5mm pitch receptacles. The identical pitch, position count, wire entry angle, and electrical ratings ensure functional compatibility. However, verify that the M3 screw specification and rising cage clamp mechanism are compatible with your application's mechanical design and assembly procedures.

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

A: The primary differences are: (1) Termination clamping mechanism (tension sleeve vs. rising cage clamp), (2) Screw size (M2.5 vs. M3), (3) Screw torque specification (0.4-0.5 Nm vs. 0.79 Nm), (4) Wire gauge accommodation (12-26 AWG vs. 12-30 AWG), (5) Operating temperature range (-20°C to 100°C vs. -40°C to 110°C), and (6) Housing material (PBT vs. PA66 Nylon 6/6). All other critical parameters remain identical.

Q: Are there any compliance or certification concerns with substitution?

A: Both parts carry identical UL94 V-0 flammability ratings and tin contact finish specifications. The TE part is RoHS compliant and carries active product status, ensuring regulatory alignment with current standards. The original Weidmüller part is obsolete, making the TE substitute the preferred choice for new designs and long-term supply assurance.

Q: What should I verify before implementing this substitution?

A: Confirm (1) mechanical fit of the M3 screw specification within your application enclosure, (2) compatibility of the rising cage clamp termination with your assembly procedures, (3) adequate torque application capability (0.79 Nm), and (4) that the extended wire gauge range does not introduce unintended application changes. Electrical and thermal specifications are fully compatible.

Q: Is the TE Connectivity part available in the same packaging as the original?

A: The TE part is supplied in bulk packaging, whereas the original Weidmüller part packaging specification is not provided. Confirm packaging and quantity requirements with your supplier for procurement planning.
