Weidmüller 1752280000 Terminal Block Equivalent & Substitute Parts

Part Overview

The Weidmüller 1752280000 is a 2-position feed-through terminal block connector rated for 4-14 AWG wire gauges, with screw termination and UL94 V-0 flammability rating. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 76 A (IEC) / 80 A (UL) and 1000V (IEC) / 600V (UL), serving as a standard connection point in industrial control and distribution applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1752280000 is determined by the following critical parameters:

• Number of Positions and Levels: Must match at 2 positions, 1 level
• Termination Style: Must be screw termination
• Electrical Ratings: Current and voltage ratings must meet or exceed IEC 76 A / 1000V and UL 80 A / 600V
• Wire Gauge Compatibility: Must accommodate the 4-14 AWG range or a subset thereof
• Material and Flammability: Insulation material and UL94 V-0 rating must be maintained
• Physical Compatibility: Terminal width, stripping length, and form factor must be compatible with existing installations
• Series Consistency: Parts from the Weidmüller W series are preferred for design continuity

The Weidmüller 1020400000 qualifies as a substitute based on these criteria, with the primary difference being wire gauge range adjustment from 4-14 AWG to 6-14 AWG.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1020400000 is the qualified substitute for the obsolete 1752280000. Selection should be based on the following engineering criteria:

Primary Consideration: The 1020400000 is currently in active production status, whereas the 1752280000 is obsolete. This makes the 1020400000 the appropriate choice for new designs and ongoing procurement.

Wire Gauge Range: The substitute accepts 6-14 AWG (1.5-16mm²) compared to the main part's 4-14 AWG (16mm²). Applications requiring 4 AWG or 5 AWG wire connections cannot use the 1020400000 without design modification.

Electrical Performance: The 1020400000 meets or exceeds all electrical ratings of the main part. IEC ratings are identical at 76 A / 1000V. UL ratings are superior at 85 A / 600V versus 80 A / 600V.

Compliance and Certifications: Both parts maintain UL94 V-0 flammability rating and identical insulation material composition. The 1020400000 carries RoHS compliance certification, providing additional regulatory alignment for modern applications.

Physical Compatibility: Terminal width difference (12.0mm vs. 11.9mm) is negligible and does not affect mechanical fit. Stripping length remains consistent at 16mm.

Frequently Asked Questions (FAQ)

Q: Can the 1020400000 directly replace the 1752280000 in all applications?

A: Direct replacement is possible for applications using wire gauges 6-14 AWG. Applications requiring 4 AWG or 5 AWG wire connections require design evaluation, as the 1020400000 does not accommodate these gauges.

Q: What is the significance of the wire gauge range difference?

A: The main part (1752280000) accepts 4-14 AWG, while the substitute (1020400000) accepts 6-14 AWG. This represents a narrower lower range on the substitute. Wire cross-sections smaller than 6 AWG cannot be terminated using the 1020400000.

Q: Are the electrical ratings compatible?

A: Yes. The 1020400000 meets or exceeds the electrical specifications of the 1752280000 across both IEC and UL standards. No derating is required.

Q: Why is the 1752280000 listed as obsolete?

A: The 1752280000 is no longer in active production. The 1020400000 represents the current production equivalent within the Weidmüller W series feed-through terminal block line.

Q: Does packaging differ between these parts?

A: The main part packaging is listed as unspecified, while the 1020400000 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Are both parts RoHS compliant?

A: The 1020400000 is explicitly RoHS compliant. RoHS status for the 1752280000 is not specified in available documentation.

Q: What is the terminal width difference impact?

A: The 0.1mm difference in terminal width (12.0mm vs. 11.9mm) is within manufacturing tolerance and does not affect mechanical compatibility or electrical performance.
