Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3073908 is determined by strict equivalence across the following critical parameters:

• Series designation (CLIPLINE UKK)
• Position and level configuration (4 positions, 2 levels)
• Connector type (Feed Through)
• Termination method (Screw)
• Electrical ratings (32A/500V IEC; 30A/600V UL)
• Wire gauge compatibility (10-26 AWG; 0.2-4mm²)
• Terminal geometry (6.2mm width)
• Insulation material and flammability rating (Polyamide PA, UL94 V-0)

The substitute part Phoenix Contact 2774017 maintains full equivalence across all these parameters. The primary difference is cosmetic (color: Gray vs. Black) and regulatory status (Active vs. Obsolete), with enhanced compliance documentation in the substitute.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 2774017 is the direct functional equivalent for applications currently using 3073908. The substitute maintains identical electrical performance, mechanical compatibility, and material specifications. The transition from RoHS to ROHS3 compliance in the substitute part reflects current regulatory standards and ensures continued supply chain viability. The substitute part is in active production status, providing assured availability for new designs and replacement applications. Color differentiation (Gray vs. Black) is a cosmetic distinction that does not affect electrical or mechanical function and should be evaluated based on system documentation and visual identification requirements.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 2774017 be used as a direct replacement for 3073908?

A: Yes. Both parts are identical in electrical ratings (32A/500V IEC, 30A/600V UL), mechanical configuration (4 positions, 2 levels, 6.2mm terminal width), wire gauge compatibility (10-26 AWG), and termination method (screw). The substitute is functionally equivalent.

Q: What is the difference between these two parts?

A: The primary differences are product status (3073908 is obsolete; 2774017 is active), color (Black vs. Gray), and regulatory compliance documentation (RoHS vs. ROHS3). Electrical and mechanical specifications are identical.

Q: Does the color difference affect compatibility?

A: No. Color is a cosmetic attribute and does not impact electrical performance, mechanical fit, or functional operation. Selection should be based on system documentation and visual identification protocols.

Q: Is the ROHS3 compliance of 2774017 compatible with systems designed for RoHS?

A: Yes. ROHS3 compliance is a superset of RoHS compliance and maintains backward compatibility with systems specified for RoHS-compliant components.

Q: What wire gauges are supported by these terminal blocks?

A: Both parts support 10-26 AWG (0.2-4mm²) conductor sizes with an 8mm stripping length requirement.

Q: Are these parts suitable for both IEC and UL applications?

A: Yes. Both parts meet IEC ratings (32A/500V) and UL ratings (30A/600V), allowing use in applications following either standard.
