Phoenix Contact 3073791 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073791 is a 1-position terminal block with bolt/screw clamp connection, designed for wire entry parallel to the panel on the front and 90° to the panel on the rear. This component is part of the CLIPLINE RW series and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is essential for ongoing system maintenance, repairs, and new designs requiring compatible terminal block solutions.

Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 3001734 qualifies as a functional substitute for the 3073791 based on the following critical parameters:

Matching Parameters:

• Single position (1 position per level)
• Identical front panel wire connection method (bolt/screw clamp, wire entry parallel to panel)
• Identical rear panel wire connection method (bolt/screw clamp, wire entry 90° to panel)
• Identical voltage rating (600 V UL)
• Identical color (gray)
• Identical panel thickness tolerance (0.039 ~ 0.236" / 1.0 ~ 6.0 mm)

Allowable Variations:

• Width: 3073791 is 0.642" (16.30 mm); 3001734 is 0.476" (12.10 mm). The narrower width of the substitute is acceptable for applications where panel space permits.
• Current rating: 3073791 is 65 A; 3001734 is 85 A. The higher current capacity of the substitute provides enhanced capability.
• Series: Different series (CLIPLINE RW vs. CLIPLINE HDFKV) with different panel mount configurations (snap lock vs. 2-piece standard).
• Product status: 3001734 is active, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3001734 is the designated substitute for the obsolete 3073791. Selection of the 3001734 is supported by the following engineering criteria:

Product Status: The 3001734 maintains active product status with current manufacturing support, ensuring long-term availability and supply chain continuity. The 3073791 is obsolete and subject to inventory depletion.

Electrical Compatibility: Both parts maintain identical voltage ratings (600 V UL) and panel thickness tolerances. The 3001734 provides a higher current rating (85 A vs. 65 A), which is a non-limiting enhancement for applications originally designed for the 3073791.

Mechanical Compatibility: Both parts feature identical wire connection methods (bolt/screw clamp, parallel front entry, 90° rear entry) and identical color specification (gray). The reduced width of the 3001734 (12.10 mm vs. 16.30 mm) is acceptable provided panel layout accommodates the narrower footprint.

Regulatory Compliance: The 3001734 meets ROHS3 compliance and REACH unaffected status, exceeding the RoHS compliance of the original part. Both parts carry EAR99 ECCN classification.

Frequently Asked Questions (FAQ)

Q: Can the 3001734 directly replace the 3073791 in existing installations?

A: The 3001734 is functionally equivalent for electrical and mechanical performance. Physical installation requires verification that the narrower width (12.10 mm vs. 16.30 mm) is compatible with the existing panel layout and mounting configuration.

Q: What is the significance of the different panel mount types?

A: The 3073791 uses a 2-piece snap lock configuration, while the 3001734 uses a standard 2-piece mount. Both are 2-piece designs suitable for panel mounting. The specific mounting mechanism may differ, requiring physical verification during installation.

Q: Does the higher current rating of the 3001734 affect compatibility?

A: No. The 3001734 current rating of 85 A exceeds the 3073791 specification of 65 A. This represents enhanced capability and does not create compatibility issues for applications designed for the original part.

Q: Are there any compliance differences between the two parts?

A: The 3001734 meets ROHS3 compliance and REACH unaffected status, while the 3073791 meets RoHS compliance. The 3001734 represents a more current regulatory standard and is preferred for new designs and long-term system support.

Q: What packaging options are available?

A: The 3073791 is supplied in standard packaging. The 3001734 is available in bulk packaging, which may affect procurement quantities and logistics considerations.
