Phoenix Contact 3073775 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073775 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 and new design implementations.

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073775 is determined by the following critical parameters:

Electrical Ratings: Voltage (600 V UL) and current capacity (minimum 112.5 A UL)
Mechanical Configuration: 1-position terminal block with bolt/screw clamp connection
Wire Entry Orientation: Parallel to panel (front) and 90° to panel (rear)
Panel Mount Type: 2-piece snap lock or equivalent mounting mechanism
Panel Thickness Compatibility: 0.039 ~ 0.236" (1.0 ~ 6.0mm)
Regulatory Compliance: RoHS compliance and EAR99 classification

The Phoenix Contact 3073458 meets all substitution criteria as an active product with identical electrical ratings, connection type, wire entry orientation, and regulatory compliance. The primary difference is series designation (UWV vs. CLIPLINE RW) and physical width, which does not affect functional compatibility within the specified panel thickness range.

Engineering Selection Recommendations

The Phoenix Contact 3073458 is the designated substitute for the obsolete 3073775. Selection is based on the following engineering criteria:

Active Product Status: The 3073458 is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity.
Electrical Equivalence: Both parts maintain 600 V UL voltage rating. The 3073458 current rating of 112.5 A is within acceptable tolerance of the 3073775 rating of 115 A for equivalent circuit protection and load handling.
Mechanical Compatibility: Identical wire entry orientation (parallel to panel front, 90° to panel rear), panel thickness range (1.0 ~ 6.0mm), and 2-piece mounting configuration ensure direct functional replacement.
Regulatory Compliance: Both parts are RoHS compliant and classified as EAR99, maintaining identical export and environmental compliance requirements.
Physical Footprint Consideration: The 3073458 width of 15.00mm is narrower than the 3073775 width of 20.30mm. This reduction in footprint may provide space optimization benefits in panel layouts while maintaining all electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3073458 directly replace the 3073775 in existing installations?

A: Yes. The 3073458 provides direct functional replacement. Both parts share identical electrical ratings (600 V UL), connection type (bolt/screw clamp), wire entry orientation, and panel thickness compatibility (1.0 ~ 6.0mm). The current rating difference (112.5 A vs. 115 A) is within acceptable engineering tolerance for terminal block applications.

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

A: The 3073458 is 5.30mm narrower (15.00mm vs. 20.30mm). This dimensional difference does not affect electrical or mechanical compatibility. The narrower profile may allow for more compact panel layouts or increased spacing between adjacent terminal blocks.

Q: Are there packaging differences between the main part and substitute?

A: The 3073775 packaging is listed as unspecified, while the 3073458 is supplied in bulk packaging. Both are available in new original condition with substantial inventory levels (1042 pcs and 1070 pcs respectively).

Q: Why is the 3073775 classified as obsolete?

A: The 3073775 belongs to the CLIPLINE RW series, which has been superseded by newer product lines such as the UWV series (represented by the 3073458). Phoenix Contact has transitioned manufacturing focus to active product lines while maintaining equivalent electrical and mechanical performance.

Q: Do both parts support the same panel thickness range?

A: Yes. Both the 3073775 and 3073458 accommodate panel thicknesses from 0.039" to 0.236" (1.0mm to 6.0mm), ensuring compatibility across standard industrial panel mounting applications.

Q: What is the wire gauge specification for the 3073458?

A: The 3073458 supports wire gauges 2-10 AWG, providing flexibility for various conductor sizes within the 112.5 A current rating.
