Phoenix Contact 0552024 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0552024 is a 2-position feed-through terminal block connector designed for wire gauges 8-26 AWG with screw termination. This component is classified as Last Time Buy, indicating discontinued production status. The CLIPLINE MBK series connector provides IEC-rated performance at 41 A and 500 V, with UL ratings of 50 A and 600 V. Due to its Last Time Buy status, identifying compatible substitute parts is essential for ongoing system design and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0552024 is determined by the following critical parameters:

Mandatory Matching Criteria:

• Number of positions: 2
• Number of levels: 1
• Terminal width: 8.2 mm
• Termination style: Screw
• Type: Feed Through
• Insulation material: Polyamide (PA), Nylon
• Color: Gray

Allowable Parameter Variations:

• Wire gauge range: The substitute may have a narrower range (8-24 AWG vs. 8-26 AWG) provided the application wire gauge falls within the substitute's supported range
• Current rating: The substitute may have lower ratings if the application current requirement does not exceed the substitute's rating
• Voltage rating: The substitute may have lower ratings if the application voltage requirement does not exceed the substitute's rating
• Flammability rating: The substitute may have a higher rating (UL94 V-0 vs. UL94 V-2)
• Stripping length: Minor variations (8-9 mm vs. 10 mm) are acceptable if installation procedures accommodate the difference

The Phoenix Contact 3248038 meets all mandatory matching criteria and qualifies as a direct substitute within defined electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3248038 is qualified as a substitute for the 0552024 based on the following engineering criteria:

Mechanical Compatibility: Both connectors share identical mechanical specifications including 2-position configuration, 1-level design, 8.2 mm terminal width, and screw termination. Physical mounting and installation interfaces are compatible.

Electrical Compatibility (IEC Standards): Both parts maintain identical IEC current (41 A) and voltage (500 V) ratings, ensuring compliance with IEC electrical performance requirements for the primary application environment.

Compliance and Certifications: The 3248038 features UL94 V-0 flammability rating, which exceeds the 0552024's UL94 V-2 rating. This represents improved fire safety performance. Both components use identical Polyamide (PA) nylon insulation materials.

Production Status: The 3248038 is in Active production status, providing long-term availability and supply chain stability compared to the 0552024's Last Time Buy status.

Application-Dependent Constraints: Substitution requires verification that the application meets the following conditions:

• Wire gauge does not exceed 24 AWG (the 0552024 supports up to 26 AWG)
• UL current requirement does not exceed 30 A (the 0552024 supports up to 50 A)
• UL voltage requirement does not exceed 500 V (the 0552024 supports up to 600 V)
• Installation procedures accommodate 8-9 mm stripping length (versus 10 mm for the original part)

Frequently Asked Questions (FAQ)

Q: Can the 3248038 directly replace the 0552024 in all applications?

A: Direct replacement is possible only when the application electrical requirements fall within the 3248038's ratings. Specifically, UL current must not exceed 30 A and UL voltage must not exceed 500 V. Wire gauge must remain within 8-24 AWG. If the original application uses 25-26 AWG wire or requires UL ratings above 30 A / 500 V, the 3248038 is not suitable.

Q: What is the significance of the different wire gauge ranges?

A: The 0552024 supports 8-26 AWG while the 3248038 supports 8-24 AWG. This means applications using 25 or 26 AWG wire cannot use the 3248038. However, applications using 8-24 AWG wire are compatible with both parts. Verify your application's wire gauge specification before selecting the substitute.

Q: Does the UL94 V-0 rating of the 3248038 provide better performance than the V-2 rating of the 0552024?

A: UL94 V-0 represents superior flammability performance compared to UL94 V-2. The 3248038 meets a higher fire safety standard. This is an improvement over the original part and does not create compatibility issues.

Q: Why does the 3248038 have lower UL current and voltage ratings?

A: The 3248038 (MUT 6 series) and 0552024 (CLIPLINE MBK series) are different product lines within Phoenix Contact's terminal block portfolio. The 3248038 is designed for different application requirements. Substitution is valid only when the application's actual electrical demands do not exceed the 3248038's ratings.

Q: Are there any installation differences due to the stripping length variation?

A: The 0552024 specifies 10 mm stripping length while the 3248038 specifies 8-9 mm. This difference requires adjustment in wire preparation procedures. Ensure installation personnel are informed of this requirement to maintain proper electrical contact and mechanical security.

Q: What is the inventory status of these parts?

A: The 0552024 has 1,073 pieces in stock but is Last Time Buy status, meaning no future production is planned. The 3248038 has 774 pieces in stock and is in Active production status, ensuring continued availability for future orders.
