Phoenix Contact 3073762 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3073762 is a 1-position terminal block with bolt/screw clamp connection, designed for parallel wire entry at the front panel and 90° wire entry at the rear panel. 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 600V UL rating with 115A current capacity and is housed in gray polymer housing with a 2-piece snap lock panel mount configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073762 is determined by the following critical parameters:

• Electrical Ratings: Voltage (600V UL) and current capacity (minimum 112.5A) must be maintained or exceeded
• Mechanical Configuration: Single position per level, bolt/screw clamp connection type, parallel front panel wire entry, and 90° rear panel wire entry
• Panel Compatibility: Panel thickness accommodation range (1.0 ~ 6.0mm) and 2-piece panel mount system
• Physical Dimensions: Width and overall form factor for panel cutout compatibility
• Compliance: RoHS compliance status for regulatory alignment

The Phoenix Contact 3073445 qualifies as a substitute based on matching electrical ratings, connection type, panel thickness range, and compliance certifications. Differences in series designation (UWV vs. CLIPLINE RW), width (15.00mm vs. 20.30mm), and product status (Active vs. Obsolete) are secondary considerations that do not prevent functional substitution when panel layout permits the dimensional change.

Engineering Selection Recommendations

Primary Substitute: Phoenix Contact 3073762 → 3073445

The 3073445 is the qualified substitute for the obsolete 3073762 based on the following engineering criteria:

• Electrical Equivalence: Both parts maintain 600V UL voltage rating. The current rating difference (115A vs. 112.5A) represents a 2.4% reduction, which is within acceptable tolerance for most industrial applications and does not constitute a functional limitation.
• Mechanical Compatibility: Identical connection types (bolt/screw clamp), panel thickness accommodation, and 2-piece panel mount configuration ensure mechanical interchangeability in standard installations.
• Compliance Alignment: Both parts are RoHS compliant, supporting regulatory requirements for new designs and system upgrades.
• Availability: The 3073445 is actively manufactured by Phoenix Contact, ensuring long-term supply chain reliability compared to the obsolete 3073762.
• Design Consideration: The 5.30mm width reduction of the 3073445 requires verification against panel cutout dimensions and adjacent component spacing in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 3073445 be used as a direct replacement for the 3073762 without any modifications?

A: The 3073445 is electrically and mechanically compatible with the 3073762 for standard bolt/screw clamp terminal block applications. However, the 5.30mm width difference must be evaluated against panel layout constraints. If the panel cutout is sized specifically for the 3073762 (20.30mm width), the narrower 3073445 (15.00mm width) may require panel modification or use of spacer components.

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

A: The 3073762 is rated for 115A while the 3073445 is rated for 112.5A. This 2.4% difference is negligible for most industrial control and power distribution applications. Selection should be based on the actual circuit current requirements; if the application requires more than 112.5A, the 3073762 specifications must be maintained or an alternative part with higher current rating must be identified.

Q: Why is the 3073762 listed as obsolete?

A: Obsolescence indicates that Phoenix Contact has discontinued manufacturing of the 3073762 in favor of newer designs such as the 3073445. The UWV series (3073445) represents the current product line for single-position terminal blocks in this configuration.

Q: Are there any differences in the panel mount mechanism between these parts?

A: Both parts use a 2-piece panel mount system. The 3073762 specifies "Snap Lock" while the 3073445 specification lists "2 Piece" without the snap lock designation. This difference should be verified with Phoenix Contact technical documentation to confirm mechanical compatibility in applications where snap lock retention is critical.

Q: What wire gauge compatibility should be verified?

A: The 3073762 does not specify wire gauge in the provided data. The 3073445 accommodates 2-10 AWG wire. When substituting, verify that the target application wire gauge falls within the 2-10 AWG range to ensure proper clamping and electrical contact.

Q: Is RoHS compliance maintained with this substitution?

A: Yes. Both the 3073762 and 3073445 are RoHS compliant, ensuring that substitution does not introduce regulatory compliance issues for applications subject to RoHS requirements.
