Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1752290000 is based on the following critical parameters that must align for functional compatibility:

• Number of Positions & Levels: Both main and substitute parts must maintain 2 positions and 1 level configuration
• Type Classification: Ground/Earth terminal block designation must be preserved
• Termination Style: Screw termination method must remain consistent
• Material & Flammability: Thermoplastic Wemid insulation with UL94 V-0 rating ensures equivalent safety performance
• Wire Gauge Compatibility: The substitute part must accommodate the wire gauge range of the original specification or provide an extended compatible range
• Terminal Width: Mechanical fit within mounting infrastructure requires compatible terminal dimensions

The Weidmüller 1010400000 qualifies as a direct substitute based on these parameters. While it supports an extended wire gauge range (4-14 AWG versus 6-14 AWG), this represents an expanded capability that maintains full compatibility with the original specification's wire gauge requirements.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1010400000 is the qualified substitute for the obsolete 1752290000. Selection is supported by the following engineering criteria:

Product Status: The 1010400000 maintains active product status, ensuring ongoing availability and manufacturer support, whereas the 1752290000 is obsolete.

Compliance & Certification: Both parts maintain identical material specifications (Thermoplastic Wemid) and flammability ratings (UL94 V-0), ensuring equivalent safety performance in grounding applications.

Functional Compatibility: The 1010400000 preserves all critical functional parameters including 2-position configuration, 1-level design, screw termination, and ground/earth type classification.

Wire Gauge Capability: The substitute part's extended wire gauge range (4-14 AWG, 1.5-25mm²) encompasses the original specification (6-14 AWG, 16mm²), providing expanded application flexibility without compromising compatibility with the original design intent.

Mechanical Fit: Terminal width variance (11.9mm versus 12.0mm) represents a negligible 0.1mm difference that does not impact mounting or electrical performance in standard terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 1010400000 directly replace the 1752290000 in existing installations?

A: Yes. The 1010400000 maintains identical functional parameters for 2-position ground terminal block applications with screw termination. The 0.1mm terminal width difference does not affect mechanical fit or electrical performance.

Q: What is the significance of the extended wire gauge range in the substitute part?

A: The 1010400000 supports 4-14 AWG (1.5-25mm²) compared to the original 6-14 AWG (16mm²). This extended range provides design flexibility for applications requiring smaller gauge conductors while maintaining full compatibility with the original specification.

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

A: No. Both parts are manufactured from identical materials (Thermoplastic Wemid) and carry the same UL94 V-0 flammability rating. REACH and ECCN classifications are equivalent.

Q: Does the stripping length difference (12mm versus 16mm) affect compatibility?

A: No. Stripping length is a preparation specification for wire termination and does not affect the electrical or mechanical compatibility of the terminal block itself.

Q: Why is the 1752290000 listed as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The 1010400000 serves as the active replacement, offering equivalent functionality with extended capabilities.

Q: What packaging is available for the substitute part?

A: The 1010400000 is available in bulk packaging, with 863 pieces currently in stock as new original inventory.
