Phoenix Contact 2812034 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2812034 is a 2-position disconnect terminal block connector rated for 12-28 AWG wire gauges, designed for applications requiring screw termination and open disconnect functionality. This component operates at 16 A (IEC) / 20 A (UL) and 500 V (IEC) / 600 V (UL). The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this series is no longer available.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2812034 is determined by the following critical parameters:

• Connector Type & Configuration: 2-position disconnect terminal block with screw termination
• Terminal Geometry: 6.2 mm terminal width for mechanical compatibility
• Wire Gauge Compatibility: Acceptable wire gauge range must overlap with or encompass 12-28 AWG (0.2-4 mm²)
• Electrical Ratings: Current and voltage ratings must meet or exceed IEC 16 A / 500 V and UL 20 A / 600 V minimums
• Insulation Material & Flammability: Polyamide (PA) / Nylon construction with UL94 V-2 or higher rating
• Termination Method: Screw-based termination required for direct mechanical substitution

The Phoenix Contact 3046168 qualifies as a substitute based on these parameters, with specific trade-offs noted in the comparison table below.

Engineering Selection Recommendations

The Phoenix Contact 3046168 is an active production substitute for the obsolete 2812034. Selection of this substitute requires evaluation of the following factors:

Voltage Rating Consideration: The 3046168 carries a UL voltage rating of 300 V, compared to the 2812034's 600 V UL rating. Applications operating at voltages between 300 V and 600 V UL must verify that the 300 V rating of the 3046168 is acceptable for the intended circuit. IEC voltage ratings are identical at 500 V.

Wire Gauge Compatibility: The 3046168 does not accommodate wire gauges 27-28 AWG. Applications requiring termination of 27-28 AWG conductors cannot use this substitute without redesign. Conversely, the 3046168 accepts 10-11 AWG wire, which the 2812034 does not support.

Compliance & Availability: The 3046168 is RoHS3 compliant and currently in active production, ensuring long-term availability and regulatory alignment. The 2812034's obsolete status necessitates transition to an alternative.

Flammability Rating: The 3046168 achieves UL94 V-0 flammability rating, superior to the 2812034's UL94 V-2 rating, providing enhanced fire safety performance.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3046168 directly replace the 2812034 in all applications?

A: Direct replacement is possible only when the application meets all of the following conditions: (1) operating voltage does not exceed 300 V UL or 500 V IEC; (2) wire gauges used fall within the 10-26 AWG range; (3) mechanical mounting and terminal width compatibility are confirmed at 6.2 mm. Applications exceeding these parameters require alternative solutions.

Q: What is the primary limitation of using 3046168 as a substitute?

A: The reduced UL voltage rating of 300 V (versus 600 V for the 2812034) is the primary constraint. Applications designed for 600 V UL operation must not use the 3046168 without circuit redesign or voltage derating analysis.

Q: Are there wire gauge incompatibilities between these parts?

A: Yes. The 2812034 supports 27-28 AWG wire, which the 3046168 does not accommodate. If your application requires 27-28 AWG termination, the 3046168 is not suitable. Conversely, if your application uses only 10-26 AWG wire, the 3046168 is compatible.

Q: Does the superior flammability rating of the 3046168 affect substitution decisions?

A: The UL94 V-0 rating of the 3046168 is superior to the 2812034's UL94 V-2 rating. This does not prevent substitution; rather, it represents an improvement in fire safety performance and may be beneficial in applications with flammability requirements.

Q: What is the packaging difference between these parts?

A: The 2812034 is listed with no specified packaging, while the 3046168 is supplied in bulk packaging. Verify that bulk packaging meets your procurement and handling requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 2812034 is RoHS Compliant, and the 3046168 is ROHS3 Compliant. Both meet RoHS requirements; the 3046168 conforms to the latest regulatory standard.
