Phoenix Contact 3073801 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073801 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 current rating of 115 A and is housed in the CLIPLINE RW series with gray coloring.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073801 is based on the following critical parameters that must remain consistent:

• Single position configuration (1 position per level)
• Bolt/screw clamp connection type with parallel panel wire entry (front) and 90° panel wire entry (rear)
• Voltage rating of 600 V UL minimum
• Current rating of 112.5 A or greater
• Panel thickness accommodation of 1.0 ~ 6.0 mm
• Gray color specification
• RoHS compliance
• Single level design

The substitute part 3073445 maintains these core electrical and mechanical parameters while differing in series designation, width, and current rating specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3073445 serves as the active substitute for the obsolete 3073801. Both components maintain identical electrical specifications (600 V, current ratings within 2.5 A of each other), mechanical connection types, and panel thickness accommodation. The 3073445 is currently in active production status, ensuring long-term availability and supply chain continuity.

The primary design difference is the reduced width of the 3073445 (15.00 mm versus 20.30 mm), which may provide space optimization benefits in panel layouts while maintaining full electrical and mechanical compatibility. The 3073445 includes specified wire gauge compatibility (2-10 AWG), providing additional clarity for conductor selection.

Both components carry RoHS compliance certification and share identical HTSUS classification, confirming regulatory equivalence for procurement and documentation purposes.

Frequently Asked Questions (FAQ)

Q: Can the 3073445 directly replace the 3073801 in existing installations?

A: Yes. Both components maintain identical voltage (600 V), equivalent current ratings (115 A vs. 112.5 A), matching connection types (bolt/screw clamp with parallel front and 90° rear wire entry), and identical panel thickness accommodation (1.0 ~ 6.0 mm). The primary physical difference is width reduction, which does not affect electrical or mechanical function.

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

A: The 3073445 is 5.30 mm narrower (15.00 mm vs. 20.30 mm). This dimensional change does not affect electrical performance or connection capability. In panel-mounted applications, the reduced width may provide layout advantages without compromising functionality.

Q: Are there compliance or certification differences between these parts?

A: No. Both components are RoHS compliant and share identical HTSUS classification (8536.69.4030), confirming regulatory and trade classification equivalence.

Q: Why is the 3073801 listed as obsolete?

A: The 3073801 has been superseded by the 3073445 in the Phoenix Contact product line. The 3073445 offers equivalent functionality with the advantage of active production status and ongoing supply availability.

Q: Does the wire gauge specification on the 3073445 indicate a limitation?

A: The 3073445 specifies 2-10 AWG wire gauge compatibility. This specification provides explicit guidance for conductor selection and does not represent a functional limitation compared to the 3073801, which did not include wire gauge documentation.
