Phoenix Contact 3029813 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3029813 is a 4-position feed-through terminal block connector designed for wire gauges 14-26 AWG with push-in spring termination. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations. The part operates at IEC-rated 17.5 A / 500V and UL-rated 15 A / 600V, with polyamide insulation rated UL94 V-0 and full RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3029813 is determined by the following critical parameters:

• Position and Level Configuration: 4 positions, 2 levels (mechanical compatibility)
• Termination Method: Push-in spring termination (functional equivalence)
• Terminal Width: 5.2 mm (physical fit requirement)
• Wire Gauge Compatibility: Minimum 14 AWG acceptance (original specification lower bound)
• Electrical Ratings: Minimum IEC 17.5 A / 500V and UL 15 A / 600V (performance floor)
• Insulation Material and Flammability: Polyamide (PA), Nylon with UL94 V-0 rating (safety and regulatory requirement)
• RoHS Compliance: Required for regulatory alignment

The substitute part Phoenix Contact 3211427 meets these criteria with the following considerations: it accepts a broader wire gauge range (12-26 AWG), provides higher current ratings (IEC 20 A / UL 20 A), and maintains identical mechanical and material specifications. The UL voltage rating differs (300V vs. 600V), which represents a constraint in certain high-voltage applications.

Engineering Selection Recommendations

The Phoenix Contact 3211427 is a direct substitute for the obsolete 3029813 based on matching mechanical configuration, termination method, and material specifications. The substitute part carries active product status, ensuring continued availability and supply chain reliability.

Key selection considerations:

• Electrical Performance: The 3211427 exceeds the original part's current ratings (20 A vs. 15-17.5 A across both standards), providing improved performance margin.
• Wire Gauge Acceptance: The expanded range (12-26 AWG vs. 14-26 AWG) offers greater flexibility for applications using smaller gauge conductors.
• Voltage Rating Variance: The UL voltage rating of the substitute (300V) is lower than the original (600V). Applications requiring 600V UL compliance must evaluate this constraint against system requirements.
• Regulatory Compliance: Both parts maintain RoHS compliance and UL94 V-0 flammability certification, meeting standard safety and environmental requirements.
• Product Lifecycle: The substitute's active status ensures long-term availability, addressing the obsolescence of the original part.

Frequently Asked Questions (FAQ)

Q: Can the 3211427 be used as a direct replacement for the 3029813 in all applications?

A: The 3211427 is mechanically and functionally compatible with the 3029813 for applications operating at or below 300V UL rating. Applications requiring 600V UL compliance must verify that the lower voltage rating of the substitute meets system specifications.

Q: What is the significance of the expanded wire gauge range (12-26 AWG) in the substitute part?

A: The 3211427 accepts wire gauges down to 12 AWG, compared to the original part's 14 AWG minimum. This allows the substitute to accommodate smaller gauge conductors without requiring additional adapters or components.

Q: Are the mechanical dimensions identical between the two parts?

A: Yes. Both parts share identical terminal width (5.2 mm), position count (4), level count (2), and push-in spring termination method, ensuring direct mechanical compatibility.

Q: Does the higher current rating of the 3211427 affect compatibility?

A: No. Higher current ratings represent improved performance capability and do not create compatibility issues. The substitute can safely handle applications within the original part's current specifications.

Q: What is the difference between IEC and UL ratings?

A: IEC ratings follow international standards, while UL ratings follow North American standards. Both ratings are provided to support global applications. The 3211427 maintains IEC 500V compliance while reducing UL voltage to 300V.

Q: Is the 3211427 RoHS compliant?

A: Yes. The 3211427 is RoHS compliant and maintains the same UL94 V-0 flammability rating as the original part, meeting regulatory requirements for both environmental and safety standards.
