Weidmüller 1733450000 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Weidmüller 1733450000 is a 2-position feed-through terminal block connector designed for wire gauges 10-26 AWG (0.5-6 mm²). This component operates at 32 A (IEC) and 400 V (IEC) with push-in spring termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new designs requiring compatible components.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 1733450000 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (IEC minimum 32 A), voltage rating (IEC minimum 400 V), and wire gauge accommodation (minimum 10-26 AWG or equivalent)
• Mechanical Compatibility: 2-position configuration, 1-level design, feed-through type, and push-in spring termination
• Physical Compatibility: Terminal width tolerance (6.1 mm reference), stripping length requirements, and connector footprint
• Material & Safety Compliance: UL94 V-0 flammability rating and thermoplastic insulation material

The Phoenix Contact 3036424 meets these substitution criteria through equivalent electrical ratings, identical positional configuration, compatible termination method, and matching safety certifications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3036424 is a qualified substitute for the Weidmüller 1733450000 based on the following factors:

• Electrical Ratings: The substitute meets or exceeds all IEC electrical specifications. The 800 V IEC rating provides additional margin over the original 400 V requirement. The 32 A current rating matches exactly.
• Mechanical Configuration: Both components share identical 2-position, 1-level feed-through architecture with push-in spring termination, ensuring mechanical interchangeability.
• Wire Gauge Accommodation: The Phoenix Contact part accommodates the full 10-26 AWG range of the original component, with extended capability to 10-28 AWG.
• Safety Compliance: Both components carry UL94 V-0 flammability certification, meeting identical safety standards.
• Product Status: The substitute is in active production, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Minor differences in terminal width (6.2 mm vs. 6.1 mm), stripping length (10 mm vs. 12 mm), and insulation material composition do not affect functional substitution within standard PCB and panel mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3036424 be used as a direct replacement for the Weidmüller 1733450000?

A: Yes. Both components share identical positional configuration (2 positions, 1 level), termination method (push-in spring), and electrical ratings (32 A IEC, 400 V IEC minimum). The Phoenix Contact part meets all functional requirements of the original component.

Q: What is the significance of the wire gauge range difference (10-26 AWG vs. 10-28 AWG)?

A: The Phoenix Contact 3036424 accommodates a wider wire gauge range, including smaller gauges down to 28 AWG. This extended capability is compatible with applications using the original 10-26 AWG range and does not create substitution conflicts.

Q: Does the 2 mm difference in stripping length (12 mm vs. 10 mm) affect compatibility?

A: No. The stripping length difference is within acceptable tolerance for push-in spring termination systems. Both values accommodate standard wire preparation practices for their respective gauge ranges.

Q: Why is the terminal width slightly different (6.1 mm vs. 6.2 mm)?

A: The 0.1 mm variance reflects manufacturing tolerances between manufacturers. Both dimensions are compatible with standard PCB pitch and panel mounting specifications for 2-position terminal blocks.

Q: What is the advantage of the higher voltage rating (800 V vs. 400 V) on the substitute part?

A: The higher IEC voltage rating on the Phoenix Contact component provides additional safety margin and allows use in higher-voltage applications while maintaining full compatibility with 400 V systems.

Q: Are there any compliance or certification differences between the two parts?

A: Both components carry UL94 V-0 flammability certification and are REACH Unaffected. The Phoenix Contact 3036424 is additionally RoHS3 Compliant, providing enhanced environmental compliance for regulated applications.

Q: How does the change from Wemid to Polyamide (PA) insulation material affect performance?

A: Both materials are thermoplastic polymers with UL94 V-0 ratings. Polyamide (PA) is a standard insulation material in modern terminal block design and provides equivalent electrical and thermal performance for this application class.
