Phoenix Contact 3073681 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073681 is a 1-position terminal block with bolt/screw clamp wire entry at 90° to the panel, rated for 600V UL and 115A UL current. This component is part of the CLIPLINE RW series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts is essential for system maintenance, repair, and new design implementations where this terminal block specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073681 is based on the following critical parameters that must be maintained for functional equivalence:

• Electrical Ratings: Voltage (600V UL) and current capacity (minimum 100A UL for the substitute)
• Mechanical Configuration: 1 position per level, 2-piece panel mount design, bolt/screw clamp connection type
• Wire Entry Orientation: 90° to panel for both front and rear connections
• Color: Gray
• Compliance: RoHS compliant status

The Weidmüller 2444660000 meets these substitution criteria. While it has a lower current rating (100A vs. 115A), it maintains the same voltage rating, mechanical mounting configuration, wire entry orientation, and compliance requirements. The width difference (0.594" vs. 0.799") reflects design optimization by the substitute manufacturer but does not affect functional compatibility in applications where the original part was specified.

Parameter Comparison

Engineering Selection Recommendations

The Weidmüller 2444660000 (WGK 25 GY BX) is an active product substitute for the obsolete Phoenix Contact 3073681. Both components are RoHS compliant and maintain identical voltage ratings at 600V UL. The substitute part carries an active product status, ensuring ongoing availability and supply chain continuity.

The primary consideration is the current rating differential: the original part is rated for 115A UL, while the substitute is rated for 100A UL. Applications operating at or below 100A UL can use the Weidmüller substitute without derating. Applications requiring the full 115A capacity of the original part must evaluate whether the 100A rating of the substitute is acceptable for the specific circuit design.

Both parts feature identical mechanical configurations (2-piece panel mount, 1 position per level, 90° wire entry orientation) and are available in gray. The Weidmüller part includes an engagement pin feature and is packaged in boxes, whereas packaging information for the original part is not specified.

Frequently Asked Questions (FAQ)

Q: Can the Weidmüller 2444660000 directly replace the Phoenix Contact 3073681?

A: Yes, for applications operating at 100A UL or below. Both parts share the same voltage rating (600V UL), mechanical configuration (2-piece panel mount, 1 position, 90° wire entry), color (gray), and compliance status (RoHS compliant). The substitute has a lower current rating (100A vs. 115A), which must be verified against your circuit requirements.

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

A: The Phoenix Contact 3073681 has a width of 0.799" (20.30mm), while the Weidmüller 2444660000 is 0.594" (15.10mm). This difference reflects design optimization by each manufacturer. Panel mounting compatibility depends on your specific panel layout and spacing requirements. Verify that the narrower substitute width accommodates your installation geometry.

Q: Are both parts RoHS compliant?

A: Yes. Both the Phoenix Contact 3073681 and Weidmüller 2444660000 are RoHS compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the Phoenix Contact 3073681 listed as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production. The Weidmüller 2444660000 is an active product, ensuring continued availability for new designs and replacement applications.

Q: What does the engagement pin feature on the Weidmüller part provide?

A: The engagement pin is a mechanical feature that aids in proper seating and alignment during installation. This feature does not affect electrical compatibility but may improve installation reliability.

Q: Are there any wire gauge specifications provided for these parts?

A: Wire gauge information is not specified for the Phoenix Contact 3073681. The Weidmüller 2444660000 supports 3-10 AWG wire gauges. Consult the detailed datasheets for both parts to confirm wire gauge compatibility with your application.
