Phoenix Contact 3073746 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073746 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 classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 600 V UL with a 65 A current rating and is housed in gray coloring with a 2-piece snap lock panel mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073746 is determined by the following critical parameters:

• Electrical Ratings: Voltage (600 V UL) and current capacity must meet or exceed the original specification
• Mechanical Configuration: Single position, bolt/screw clamp connection type, and wire entry orientation (parallel front, 90° rear)
• Panel Compatibility: Panel thickness range (1.0 ~ 6.0 mm) and mounting method (2-piece configuration)
• Physical Dimensions: Width and overall form factor for panel cutout compatibility
• Color and Compliance: Gray coloring and RoHS compliance status

The Phoenix Contact 3073445 qualifies as a substitute based on matching electrical voltage, mechanical connection type, panel thickness range, single-position configuration, color, and RoHS compliance. The substitute part operates at a higher current rating (112.5 A versus 65 A), providing enhanced capacity. Width variation (15.00 mm versus 16.30 mm) and series designation change (UWV versus CLIPLINE RW) reflect design evolution within the Phoenix Contact terminal block portfolio.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3073445 is the designated substitute for the obsolete 3073746 based on functional and electrical equivalence. Both parts maintain identical voltage ratings (600 V UL), identical panel thickness compatibility (1.0 ~ 6.0 mm), and identical mechanical connection architecture (bolt/screw clamp with parallel front and 90° rear wire entry). Both components are RoHS compliant, meeting current environmental and regulatory standards.

The 3073445 operates at 112.5 A current capacity, which exceeds the original 65 A specification, providing additional margin for circuit protection and thermal management. The active product status of the 3073445 ensures ongoing availability and manufacturing support, eliminating supply chain risk associated with the obsolete 3073746.

Width reduction from 16.30 mm to 15.00 mm reflects design optimization and does not impact electrical or mechanical function. Panel cutout dimensions must be verified during physical integration to accommodate the narrower profile.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3073445 be used as a direct replacement for the 3073746?

A: Yes. Both parts share identical electrical ratings (600 V), identical panel thickness compatibility (1.0 ~ 6.0 mm), identical connection type (bolt/screw clamp), and identical wire entry orientation. The 3073445 provides higher current capacity (112.5 A versus 65 A) and active product status.

Q: What is the significance of the width difference between the two parts?

A: The 3073445 is 1.30 mm narrower (15.00 mm versus 16.30 mm). This dimension change reflects design evolution but does not affect electrical performance. Panel cutout dimensions must be verified during installation to ensure mechanical fit.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3073746 and 3073445 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the 3073746 classified as obsolete?

A: The 3073746 has been superseded by the 3073445 within the Phoenix Contact product line. The substitute part provides equivalent functionality with enhanced current capacity and active manufacturing support.

Q: Does the panel mount type difference affect compatibility?

A: Both parts use 2-piece panel mount configurations. The original specifies "snap lock" while the substitute specifies "2 piece." This represents a minor design variation that does not impact functional compatibility for standard panel mounting applications.

Q: What wire gauge range is supported?

A: The substitute part 3073445 supports 2-10 AWG wire gauge. Wire gauge information for the original 3073746 was not provided in the specification data.
