Substitute Part Grouping Explanation

Substitution eligibility for the 1752260000 is determined by the following critical parameters:

Connector Type & Configuration: Feed-through terminal block with 2 positions and 1 level
Termination Method: Screw termination
Electrical Ratings: Current capacity (57 A IEC / 65 A UL) and voltage withstand (800 V IEC / 600 V UL minimum)
Wire Gauge Compatibility: Support for 6-18 AWG wire range
Physical Compatibility: Terminal width and stripping length alignment
Material & Compliance: Thermoplastic Wemid insulation with UL94 V-0 flammability rating

The substitute part 1020300000 maintains functional equivalence through matching connector topology, termination style, position count, and core electrical specifications. Variations in wire gauge range (6-16 AWG vs. 6-18 AWG) and terminal width (9.9 mm vs. 10.0 mm) represent minor design refinements within acceptable substitution parameters.

Engineering Selection Recommendations

The Weidmüller 1020300000 is the designated substitute for the obsolete 1752260000. Selection rationale is based on the following factors:

Product Status: The 1020300000 maintains active production status, ensuring ongoing availability and supply chain reliability. The 1752260000 is classified as obsolete, creating procurement risk for new designs and long-term maintenance applications.

Electrical Equivalence: Both parts maintain identical current ratings (57 A IEC / 65 A UL) and equivalent voltage performance (1000 V IEC for 1020300000 exceeds the 800 V IEC requirement of 1752260000; both rated 600 V UL). Electrical compatibility is confirmed across standard industrial applications.

Compliance & Certification: Both components feature UL94 V-0 flammability rating and identical insulation material composition (Thermoplastic, Wemid). The 1020300000 carries RoHS compliance certification, meeting modern regulatory requirements for new equipment designs.

Physical & Functional Compatibility: Matching 2-position, 1-level feed-through configuration with screw termination. Terminal width differential (9.9 mm vs. 10.0 mm) and wire gauge range variation (6-16 AWG vs. 6-18 AWG) fall within acceptable mechanical tolerance for standard PCB and panel mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 1020300000 directly replace the 1752260000 in existing installations?

A: Yes. Both components share identical connector topology, position count, termination method, and core electrical ratings. The 1020300000 provides equivalent or superior performance across all specified parameters.

Q: What is the significance of the wire gauge range difference (6-18 AWG vs. 6-16 AWG)?

A: The 1752260000 accommodates 18 AWG wire, while the 1020300000 supports 6-16 AWG. For applications using 18 AWG conductors, the 1752260000 specification must be retained. For 6-16 AWG applications, both parts are functionally equivalent.

Q: Why does the 1020300000 have a higher IEC voltage rating (1000 V vs. 800 V)?

A: The 1020300000 represents a design refinement with enhanced voltage withstand capability. This higher rating does not affect compatibility and provides additional safety margin for applications operating at or below 800 V IEC.

Q: Is the 0.1 mm terminal width difference (10.0 mm vs. 9.9 mm) significant?

A: No. This 0.1 mm variation is within standard manufacturing tolerance and does not affect mechanical fit, electrical performance, or PCB mounting compatibility.

Q: What packaging options are available for the substitute part?

A: The 1020300000 is supplied in bulk packaging, compared to the unspecified packaging of the obsolete 1752260000. Bulk packaging is standard for active production components and supports efficient inventory management.

Q: Does the RoHS compliance of the 1020300000 affect compatibility?

A: No. RoHS compliance of the 1020300000 indicates adherence to modern environmental and material standards. This certification does not impact electrical or mechanical compatibility with existing designs.
