Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 67601493 is determined by the following critical parameters:

• Number of Positions and Levels: Must be 2 positions, 1 level to maintain circuit configuration compatibility
• Termination Style: Must be screw termination for mechanical and electrical consistency
• Disconnect Type: Must include fuse and lever functionality
• Current and Voltage Ratings: Must meet or exceed 30 A at 600V UL specifications
• Wire Gauge Compatibility: Must accommodate the required wire gauge range; substitutes with expanded ranges (4-18 AWG) are acceptable as they provide broader application flexibility
• Terminal Width: Minor variations are acceptable within standard manufacturing tolerances

The Weidmüller 1966060000 qualifies as a substitute based on these criteria. While it belongs to a different series (WSI) and has a slightly expanded wire gauge range (4-18 AWG versus 6-18 AWG), it maintains all critical functional and electrical parameters required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 1966060000 is the qualified substitute for the obsolete 67601493 based on the following engineering criteria:

Functional Equivalence: Both components maintain identical circuit configuration (2 positions, 1 level) and disconnect functionality (fuse and lever operation). Screw termination is preserved, ensuring compatibility with existing wiring practices.

Electrical Specifications: The substitute meets the current (30 A) and voltage (600V UL) requirements of the original component. The expanded wire gauge range (4-18 AWG) provides additional flexibility without compromising the original 6-18 AWG specification.

Product Status and Compliance: The 1966060000 is an active product with RoHS compliance certification, providing long-term availability and regulatory alignment. The original component's obsolete status necessitates this transition.

Physical Compatibility: Terminal width variation (17.7mm to 18.0mm) falls within acceptable manufacturing tolerances and does not impact mechanical or electrical performance in standard mounting configurations.

Regulatory Considerations: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining regulatory consistency in supply chain documentation.

Frequently Asked Questions (FAQ)

Q: Can the 1966060000 directly replace the 67601493 in existing installations?

A: Yes. Both components share identical electrical ratings (30 A, 600V), disconnect functionality, screw termination, and 2-position configuration. The terminal width difference (0.3mm) is within standard tolerances and does not affect mounting or performance.

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

A: The 1966060000 accepts 4-18 AWG wire, compared to the original 6-18 AWG specification. This expanded range maintains full compatibility with the original specification while providing additional application flexibility for smaller gauge conductors.

Q: Are there differences in fuse compatibility between the two parts?

A: Yes. The original component uses 1.5" x 13/32" fuses, while the substitute uses 10.3mm x 38mm fuses. Fuse selection must be updated accordingly when transitioning to the substitute component.

Q: How do the insulation materials differ?

A: The original uses Polyamide (PA) and Nylon, while the substitute uses Thermoplastic and Wemid. Both materials provide equivalent electrical insulation and mechanical properties for this application category.

Q: What is the advantage of the substitute's RoHS compliance?

A: RoHS compliance ensures the component meets current environmental and regulatory standards for electronic equipment manufacturing and disposal, providing assurance for long-term supply chain viability and regulatory alignment.

Q: Does the color difference (White to Beige) affect functionality?

A: No. Color is a visual identification feature only and does not impact electrical or mechanical performance. The color change reflects series differentiation between USI 16 and WSI product lines.

Q: Is the substitute suitable for new designs?

A: Yes. The 1966060000 is an active product with current manufacturing support, making it the appropriate choice for new designs requiring 2-position disconnect terminal block functionality with fuse and lever operation.
