Substitute Part Grouping Explanation

Substitution of terminal block connectors is determined by functional equivalence across critical electrical and mechanical parameters. For the 331130, the primary substitution criteria are:

• Number of Positions and Levels: Both main and substitute parts must maintain 2-position, 1-level configuration to ensure mechanical fit and electrical connectivity in existing assemblies.
• Terminal Width: 6.0mm terminal width is a fixed mechanical constraint that must be preserved.
• Termination Style: Screw termination is required for compatibility with existing wiring practices and installation procedures.
• Wire Gauge Compatibility: The substitute must accommodate the wire gauge range of the original part. The 331130 accepts 12-26 AWG; acceptable substitutes must support this range or a superset thereof.
• Insulation Material and Flammability: Polyamide (PA66) with UL94 V-2 rating ensures electrical safety and thermal performance in ground applications.
• Color Coding: Green and Yellow coloring is standard for ground/earth terminals and must be maintained.
• Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment.

The American Electrical Inc. 334120 meets all substitution criteria as an active product with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The American Electrical Inc. 334120 is the qualified substitute for the obsolete 331130 terminal block connector. Selection is based on the following engineering criteria:

Functional Equivalence: Both parts share identical core specifications—2-position configuration, 6.0mm terminal width, screw termination, and polyamide insulation with UL94 V-2 rating. These parameters ensure mechanical and electrical compatibility in ground terminal applications.

Wire Gauge Accommodation: The 334120 supports a wire gauge range of 10-26 AWG, which encompasses the 12-26 AWG range of the 331130. This extended lower range provides additional flexibility without compromising compatibility with the original specification.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring continued adherence to environmental and safety regulations.

Product Availability: The 334120 is classified as active with 1967 units in stock, providing reliable supply continuity for applications currently using the obsolete 331130.

Series Transition: The 334120 belongs to the AVK series, representing an evolution from the WGT series. This transition reflects current manufacturing standards while preserving functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 334120 directly replace the 331130 in existing installations?

A: Yes. Both parts maintain identical mechanical dimensions (6.0mm terminal width, 2-position configuration) and electrical specifications (screw termination, polyamide insulation, UL94 V-2 rating). The 334120 is mechanically and electrically compatible with applications designed for the 331130.

Q: What is the difference in wire gauge specifications between these parts?

A: The 331130 accepts 12-26 AWG wire, while the 334120 accepts 10-26 AWG wire. The 334120 supports an extended lower range, accommodating larger diameter conductors. For applications using 12-26 AWG wire, both parts are functionally equivalent.

Q: Are there packaging differences between the 331130 and 334120?

A: The 331130 packaging is not specified in available documentation. The 334120 is supplied in box packaging. Verify packaging requirements for your specific application and procurement process.

Q: Do both parts meet the same safety and environmental standards?

A: Yes. Both the 331130 and 334120 are ROHS3 compliant and REACH unaffected. Both carry UL94 V-2 flammability ratings for polyamide insulation, ensuring equivalent safety performance in ground terminal applications.

Q: Why is the 331130 classified as obsolete?

A: The 331130 is no longer in active production. The 334120 represents the current active equivalent from American Electrical Inc., offering the same functional performance with improved supply availability.

Q: What is the stripping length difference, and does it affect compatibility?

A: The 331130 specifies 12mm stripping length, while the 334120 specifies 10mm. Stripping length is a preparation parameter for wire installation. Verify that your installation procedures accommodate the 10mm stripping length of the 334120 to ensure proper terminal contact and electrical performance.
