Phoenix Contact 3073814 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073814 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 substitute parts is essential for ongoing system maintenance, repairs, and new designs requiring compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073814 is determined by the following critical parameters:

• Electrical Specifications: Voltage rating (600 V UL) and current capacity (minimum 112.5 A)
• Mechanical Configuration: 1 position per level, bolt/screw clamp connection type, wire entry orientation (parallel to panel front, 90° to panel rear)
• Panel Interface: 2-piece mounting system compatible with panel thickness range of 0.039" to 0.236" (1.0 to 6.0 mm)
• Compliance: RoHS compliance and engagement pin feature
• Color: Gray housing

The substitute part Phoenix Contact 3073458 meets these criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3073458 serves as a functional substitute for the obsolete 3073814 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain 600 V UL voltage rating. The current capacity of 3073458 (112.5 A) remains within acceptable operating parameters for applications previously using the 3073814 (115 A), with a 2.5 A reduction that does not compromise standard industrial terminal block applications.

Mechanical Compatibility: Both parts feature identical wire connection methods (bolt/screw clamp with parallel front entry and 90° rear entry), single-position configuration, and compatible panel thickness ranges. The engagement pin feature is retained in the substitute.

Compliance and Status: The 3073458 is an active product with RoHS compliance certification, ensuring long-term availability and regulatory alignment. The 3073814's obsolete status necessitates transition to the substitute for new procurements and system updates.

Physical Footprint Consideration: The 3073458 has a reduced width (0.591" versus 0.799"), which may require panel layout verification in space-constrained applications but generally provides design flexibility.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3073458 directly replace the 3073814 in existing installations?

A: Yes, the 3073458 is mechanically and electrically compatible. Both parts share identical wire connection orientations, panel mounting interfaces, and voltage specifications. Panel thickness compatibility ranges are identical. Physical width difference (0.591" versus 0.799") should be verified for space constraints.

Q: What is the significance of the current rating difference (115 A versus 112.5 A)?

A: The 2.5 A difference represents a 2.2% reduction in maximum current capacity. For standard industrial applications, this variance is within acceptable tolerance and does not affect functional compatibility. Applications operating near maximum current limits should be evaluated individually.

Q: Are both parts RoHS compliant?

A: Yes, both the 3073814 and 3073458 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the 3073814 classified as obsolete?

A: The obsolete status indicates that Phoenix Contact has discontinued production and support for this part. The 3073458 from the UWV series represents the current product line equivalent.

Q: Does the series change from CLIPLINE RW to UWV affect compatibility?

A: Series designation reflects product line organization. The functional parameters—electrical ratings, mechanical configuration, and connection methods—remain compatible. Series change does not impact substitution viability.

Q: What packaging options are available for the substitute part?

A: The 3073458 is supplied in bulk packaging, whereas the original 3073814 packaging specification was not provided. Bulk packaging is standard for industrial terminal block procurement.
