Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3050329 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Wire gauge range (14-20 AWG / 0.5-2.5mm²), terminal width (6.2mm), and number of positions (3)
• Mechanical Compatibility: Single-level configuration, ground/earth type designation, and terminal block form factor
• Material & Safety Compliance: Polyamide insulation with UL94 V-0 flammability rating, RoHS compliance status
• Functional Equivalence: Termination capability via IDC and/or screw methods

The substitute part Phoenix Contact 3206474 meets all these criteria while offering improved product status (Active vs. Last Time Buy) and enhanced compliance documentation (ROHS3 Compliant, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3206474 is the direct substitute for the 3050329. Both components share identical electrical and mechanical specifications: 3-position ground terminal block, 14-20 AWG wire gauge capacity, 6.2mm terminal width, and UL94 V-0 polyamide insulation.

The 3206474 offers superior product lifecycle status (Active production vs. Last Time Buy), ensuring long-term availability and supply chain stability. The substitute maintains full RoHS compliance with enhanced ROHS3 certification and includes REACH Unaffected documentation, meeting current regulatory requirements.

The primary difference is termination method: the 3050329 supports both IDC and screw termination, while the 3206474 supports IDC termination only. Applications requiring screw-only termination must evaluate this distinction against design requirements.

Frequently Asked Questions (FAQ)

Q: Are the 3050329 and 3206474 electrically interchangeable?

A: Yes. Both components support identical wire gauge ranges (14-20 AWG / 0.5-2.5mm²), feature 3-position ground configurations, and maintain equivalent electrical performance through polyamide insulation with UL94 V-0 rating.

Q: What is the difference in termination methods?

A: The 3050329 supports both IDC (Insulation Displacement Connector) and screw termination. The 3206474 supports IDC termination only. Designs utilizing screw termination exclusively should confirm compatibility with the substitute's IDC-only specification.

Q: Why is the 3050329 listed as Last Time Buy?

A: Last Time Buy status indicates Phoenix Contact has discontinued production of this part number. The 3206474 represents the active production equivalent within the CLIPLINE terminal block family.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The 3206474 carries ROHS3 Compliant certification and REACH Unaffected status, providing enhanced regulatory documentation. The 3050329 lists RoHS Compliant status without additional certifications.

Q: Can I use the 3206474 in existing designs specified for the 3050329?

A: Substitution is valid for applications using IDC termination. Applications requiring screw termination capability must evaluate whether the IDC-only specification of the 3206474 meets design constraints.

Q: What is the inventory status of these parts?

A: The 3050329 has 708 pieces in stock (Last Time Buy status). The 3206474 has 1137 pieces in stock (Active production status), indicating greater availability for new orders.
