Phoenix Contact 0452043 Terminal Block Ground Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 0452043 is a 2-position ground terminal block connector designed for wire gauges 14-26 AWG (0.2-6 mm²). This component is classified as Last Time Buy, indicating discontinued production. The CLIPLINE MBK series connector features screw termination, polyamide insulation with UL94 V-0 flammability rating, and green/yellow color coding for ground/earth applications. Locating equivalent substitute parts is necessary due to product discontinuation and inventory depletion.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 0452043 is determined by the following critical parameters:

• Number of Positions and Levels: Must remain 2 positions, 1 level
• Terminal Width: Must be 6.2 mm for mechanical compatibility
• Termination Style: Must be screw termination
• Type: Must be Ground/Earth application
• Color Coding: Must be Green/Yellow
• Insulation Material: Must be Polyamide (PA), Nylon with UL94 V-0 rating
• Wire Gauge Compatibility: Acceptable range is 10-26 AWG (0.2-6 mm²) with overlap to the original specification

The Phoenix Contact 3248037 qualifies as a direct substitute based on these parameters. While the wire gauge range differs slightly (10-24 AWG versus 14-26 AWG), the overlap range of 14-24 AWG ensures compatibility for the majority of applications within the original specification envelope.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3248037 is the qualified substitute for the 0452043. Selection is based on the following engineering criteria:

Compliance and Regulatory Status: The 3248037 maintains RoHS3 compliance, exceeding the RoHS compliance of the original part. Both components carry UL94 V-0 flammability certification, meeting fire safety requirements for insulation materials.

Product Lifecycle: The 3248037 is classified as Active, ensuring continued availability and supply chain stability. The original 0452043 is Last Time Buy, making transition to the substitute necessary for long-term design continuity.

Mechanical and Electrical Compatibility: Both parts share identical terminal width (6.2 mm), screw termination, 2-position/1-level configuration, and ground/earth type designation. The wire gauge overlap (14-24 AWG) covers standard applications within the original specification range.

Series Transition: The substitute represents a transition from the CLIPLINE MBK series to the CLIPLINE UT series, both manufactured by Phoenix Contact with equivalent performance characteristics for ground terminal block applications.

Frequently Asked Questions (FAQ)

Q: Can the 3248037 be used in place of the 0452043 in all applications?

A: The 3248037 is compatible for applications using wire gauges within the overlap range of 14-24 AWG. Applications requiring 25-26 AWG wire gauges must be evaluated separately, as the substitute part is rated only to 24 AWG maximum.

Q: What is the difference between the CLIPLINE MBK and CLIPLINE UT series?

A: Both series are Phoenix Contact ground terminal block connectors with identical mechanical and electrical specifications for this 2-position configuration. The CLIPLINE UT series represents the current production line, while CLIPLINE MBK is discontinued.

Q: Are there any packaging differences between these parts?

A: Both parts are supplied in Bulk packaging. No special handling or packaging modifications are required for substitution.

Q: Does the stripping length difference (8 mm vs. 9 mm) affect compatibility?

A: The stripping length is a preparation specification for wire termination. The 1 mm difference does not affect mechanical or electrical compatibility. Standard wire preparation practices accommodate both specifications.

Q: Is the 3248037 suitable for new designs?

A: Yes. The 3248037 is classified as Active and is the recommended component for new designs requiring 2-position ground terminal blocks in the Phoenix Contact CLIPLINE product family.
