Phoenix Contact 0443010 Terminal Block Ground Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0443010 is a 2-position ground terminal block connector designed for wire gauges 6-24 AWG (0.5-16mm²). This component is classified as a Last Time Buy product, indicating discontinued production with limited remaining inventory of 710 pieces. Ground terminal blocks serve as dedicated earth connection points in electrical systems, providing secure screw-type termination for grounding conductors. Identification of equivalent substitute parts is necessary due to the Last Time Buy status and to ensure continued availability for maintenance and new installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0443010 is determined by the following critical parameters:

• Functional Type: Ground/Earth terminal block connector
• Number of Positions: 2 positions
• Number of Levels: 1 level
• Terminal Width: 10.2mm (mechanical compatibility)
• Termination Style: Screw-type connection
• Wire Gauge Compatibility: Overlap within 6-24 AWG range
• Material Composition: Polyamide (PA) insulation
• Color Coding: Green and Yellow earth identification
• Regulatory Compliance: ROHS3 and REACH compliance

The substitute part Phoenix Contact 3044173 maintains compatibility across these core parameters. Variations in current rating (82 A vs. 57 A), flammability rating (UL94 V-2 vs. UL94 V-0), and wire gauge upper limit (24 AWG vs. 20 AWG) represent design differences within the same product family and do not preclude substitution where application requirements permit.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3044173 is the designated manufacturer-recommended substitute for the 0443010. Selection between these parts should be based on the following criteria:

Select 0443010 when:

• Current requirements approach or exceed 57 A
• Wire gauges larger than 20 AWG (24 AWG) are required
• Existing installations use CLIPLINE USLKG series components

Select 3044173 when:

• Active product availability is required for long-term supply chain continuity
• Current requirements do not exceed 57 A
• Wire gauges up to 20 AWG satisfy application needs
• Enhanced flammability performance (UL94 V-0) is specified
• New installations benefit from CLIPLINE UT series standardization

Both parts maintain ROHS3 compliance and REACH compliance status. The 3044173 offers superior product status as an Active component with higher inventory availability (3174 pieces), supporting ongoing procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3044173 directly replace the 0443010 in existing installations?

A: Direct replacement is possible when application current requirements do not exceed 57 A and wire gauges do not exceed 20 AWG. Verify that the connected conductor sizes fall within the 6-20 AWG range of the substitute part.

Q: What is the significance of the Last Time Buy status for the 0443010?

A: Last Time Buy indicates that Phoenix Contact has discontinued production of this part. The remaining inventory of 710 pieces represents the final available stock. New designs and long-term applications should transition to the Active substitute part 3044173.

Q: Are there mechanical compatibility concerns between the two parts?

A: Both parts share identical terminal width (10.2mm), number of positions (2), and screw termination style. Mechanical mounting and connection interfaces are compatible.

Q: How do the current ratings differ between these parts?

A: The 0443010 is rated for 82 A (IEC), while the 3044173 is rated for 57 A (IEC). Selection should be based on the maximum continuous current in the grounding circuit.

Q: What is the difference in wire gauge capacity?

A: The 0443010 accommodates 6-24 AWG conductors, while the 3044173 accommodates 6-20 AWG conductors. Both support the full 0.5-16mm² metric range. Applications using 22 or 24 AWG conductors require the 0443010.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and REACH affected. The 3044173 achieves a higher flammability rating (UL94 V-0) compared to the 0443010 (UL94 V-2).

Q: What is the difference in stripping length?

A: The 0443010 requires 11mm conductor stripping length, while the 3044173 requires 10mm. Ensure proper conductor preparation according to the selected part's specification.
