Key Parameters

Substitute Part Grouping Explanation

Substitution of the Weidmüller 0401220000 is determined by the following critical parameters:

• Electrical Ratings: Current and voltage ratings must meet or exceed IEC 20A/500V and UL 13A/300V specifications
• Physical Configuration: 3-position feed-through design with 6.5mm terminal width
• Wire Compatibility: Support for 12-26 AWG (0.33-6mm²) wire gauges
• Termination Method: Screw and tab termination capability
• Series Compatibility: SAK series maintains mechanical and electrical interchangeability

The substitute part 0401260000 satisfies all these criteria while offering active product status and improved material specifications.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 0401260000 serves as the direct substitute for the obsolete 0401220000. Both components maintain identical electrical ratings, physical dimensions, and wire gauge compatibility within the SAK series. The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability.

Material composition differs between the two parts: the original uses Gemin thermosetting plastic with UL94 5VA rating, while the substitute employs Polyamide (PA66) Nylon 6/6 with UL94 V-2 rating. Both materials satisfy standard terminal block application requirements and maintain compliance with applicable regulatory standards.

Frequently Asked Questions (FAQ)

Q: Can the 0401260000 directly replace the 0401220000 in existing applications?

A: Yes. Both components share identical electrical ratings (IEC 20A/500V, UL 13A/300V), physical configuration (3-position feed-through), wire gauge compatibility (12-26 AWG), and termination method (screw and tab). The substitute maintains full functional equivalence.

Q: What is the significance of the color difference between these parts?

A: Color designation (yellow vs. beige) serves as a visual identifier but does not affect electrical or mechanical performance. Selection should be based on application requirements and system documentation.

Q: How do the insulation materials differ between these parts?

A: The original part uses Gemin thermosetting plastic (UL94 5VA), while the substitute uses Polyamide PA66 Nylon 6/6 (UL94 V-2). Both materials meet standard flammability requirements for terminal block applications. Material selection should align with specific environmental and regulatory requirements of the application.

Q: Why is the original part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 0401260000 substitute remains in active production, providing continuity for applications requiring SAK series 3-position feed-through terminal blocks.

Q: Are there packaging differences between these parts?

A: The original part is listed with no specified packaging, while the substitute is supplied in bulk packaging. Confirm packaging requirements with procurement specifications for your application.
