Phoenix Contact 3056129 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3056129 is a 1-position terminal block with bolt/screw clamp wire entry at 90° to the panel, designed for panel-mount applications. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The CLIPLINE RW series construction provides reliable wire termination for applications requiring secure mechanical connections.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Phoenix Contact 3056129 is based on the following critical parameters:

• Functional equivalence: Single-position terminal block configuration
• Connection method: Bolt/screw clamp with 90° wire entry to panel
• Panel mounting: 2-piece mount system
• Wire gauge compatibility: Overlap within acceptable range (6-20 AWG minimum requirement)
• Material and color: Gray housing for visual identification and environmental consistency
• Regulatory compliance: RoHS compliance maintained across substitutes

The Phoenix Contact 3073335 (CLIPLINE UW series) satisfies these substitution criteria as an active product with compatible electrical and mechanical interfaces.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3073335 is the designated substitute for the obsolete 3056129 based on the following factors:

• Active product status: The 3073335 is currently in active production, ensuring long-term availability and supply chain continuity.
• Regulatory compliance: Both components maintain RoHS compliance, with the substitute meeting ROHS3 specifications.
• Functional compatibility: Identical single-position configuration, bolt/screw clamp connection method, and 2-piece panel mount system.
• Electrical ratings: The substitute provides specified UL voltage (600 V) and current (65 A) ratings, establishing clear performance parameters.
• Physical constraints: The substitute has a reduced width (0.398" vs. 0.642") and narrower panel thickness range (1.0-4.0mm vs. 1.0-6.0mm). Panel thickness compatibility must be verified for applications using panels thicker than 4.0mm.
• Wire gauge consideration: The substitute supports 6-20 AWG, which covers the majority of the original 6-26 AWG range. Applications requiring wire gauges larger than 20 AWG require alternative evaluation.

Frequently Asked Questions (FAQ)

Q: Can the 3073335 directly replace the 3056129 in all applications?

A: The 3073335 is functionally equivalent for most applications. However, verify panel thickness (maximum 4.0mm for substitute vs. 6.0mm for original) and wire gauge requirements (maximum 20 AWG for substitute vs. 26 AWG for original) before implementation.

Q: What is the primary reason for substitution?

A: The 3056129 is obsolete and no longer manufactured. The 3073335 provides equivalent functionality as an active product from the same manufacturer.

Q: Are there differences in physical dimensions?

A: Yes. The 3073335 is narrower (0.398" vs. 0.642") and has a reduced maximum panel thickness rating (4.0mm vs. 6.0mm). Panel cutout and mounting hole spacing must be verified for compatibility with existing installations.

Q: Do both components have the same wire connection method?

A: Yes. Both use bolt/screw clamp connections with 90° wire entry to the panel, ensuring identical termination procedures.

Q: What compliance certifications apply?

A: Both components are RoHS compliant. The substitute meets ROHS3 specifications. Both have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: Are electrical ratings specified for the original part?

A: The 3056129 does not have published UL voltage and current ratings in the available documentation. The 3073335 is rated for 600 V and 65 A per UL standards.
