Phoenix Contact 2812018 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2812018 is a 2-position disconnect terminal block connector rated for 12-28 AWG wire gauges, with screw termination and rated for 16 A (IEC) / 20 A (UL) at 500V (IEC) / 600V (UL). This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2812018 is determined by the following critical parameters:

• Mechanical Compatibility: 2 positions, 1 level, 6.2mm terminal width, screw termination, disconnect type (open)
• Electrical Ratings: Current and voltage ratings must meet or exceed the application requirements
• Wire Gauge Compatibility: Wire gauge range must accommodate the conductor sizes used in the application
• Material and Compliance: Insulation material, flammability rating, and regulatory compliance (RoHS, REACH)

The Phoenix Contact 3046142 qualifies as a substitute based on matching mechanical form factor (2 positions, 1 level, 6.2mm terminal width, screw termination) and overlapping wire gauge acceptance range. Both components are gray disconnect terminal blocks from the Phoenix Contact product line.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3046142 is an active product suitable for replacing the obsolete 2812018 in applications where wire gauges fall within the 10-26 AWG range. The 3046142 offers improved flammability performance (UL94 V-0 versus V-2) and current capacity under IEC ratings (20 A versus 16 A), while maintaining equivalent voltage ratings and mechanical compatibility.

For applications requiring wire gauges smaller than 10 AWG or larger than 26 AWG, the 3046142 may not be suitable. Applications using wire gauges in the 12-26 AWG overlap range can transition to the 3046142 without modification to wire preparation or installation procedures.

The 3046142 carries ROHS3 and REACH compliance certifications, meeting current regulatory requirements for new designs and procurement.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3046142 directly replace the 2812018 in all applications?

A: Direct replacement is possible only for applications using wire gauges within the 10-26 AWG range. The 2812018 accepts 12-28 AWG wire, while the 3046142 accepts 10-26 AWG. Applications using 27-28 AWG wire require alternative solutions.

Q: What is the difference in current ratings between these two parts?

A: Under IEC standards, the 3046142 is rated for 20 A compared to the 2812018 at 16 A. Under UL standards, the 2812018 is rated for 20 A compared to the 3046142 at 16 A. Selection depends on the applicable regulatory standard for the application.

Q: Does the improved flammability rating of the 3046142 affect compatibility?

A: The UL94 V-0 rating of the 3046142 represents improved fire performance compared to the V-2 rating of the 2812018. This enhancement does not reduce compatibility; it provides better safety characteristics for the same mechanical and electrical function.

Q: Are there packaging differences between these parts?

A: The 2812018 is listed with no specified packaging, while the 3046142 is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What regulatory compliance should I consider for new designs?

A: The 3046142 carries ROHS3 and REACH compliance certifications, meeting current regulatory standards. The 2812018, being obsolete, should not be specified for new designs.
