Phoenix Contact 3050057 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3050057 is a 3-position feed-through terminal block connector designed for wire gauges 12-26 AWG (0.25-1.5 mm²). This component features screw and IDC termination styles, rated for 17.5 A at 800V (IEC) and 10 A at 600V (UL). The part is classified as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is necessary to ensure continued availability and maintain design compatibility in applications requiring this terminal block specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3050057 is based on the following critical parameters that must remain consistent:

• Number of positions: 3
• Terminal block type: Feed through
• Terminal width: 5.2 mm
• Color: Blue
• Material composition: Polyamide (PA), Nylon
• Flammability rating: UL94 V-0
• Current rating (IEC): 17.5 A
• Voltage rating (IEC): 800V
• Current rating (UL): 10 A
• Voltage rating (UL): 600V
• RoHS compliance: Required

The Phoenix Contact 3205051 qualifies as a substitute part. While the wire gauge range differs (16-24 AWG versus 12-26 AWG), all electrical ratings, mechanical dimensions, material specifications, and compliance certifications remain equivalent. The termination style differs (IDC only versus IDC and screw), representing a functional constraint that must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3205051 is the designated manufacturer substitute for the 3050057. Selection of this substitute part is supported by the following factors:

• All electrical ratings (current and voltage) are identical across both IEC and UL standards
• Mechanical dimensions and terminal specifications are equivalent
• Material composition and flammability certification (UL94 V-0) are identical
• Both parts maintain RoHS compliance
• The 3205051 carries Active product status, ensuring continued availability and supply chain stability

Two constraints require evaluation:

1. Wire gauge range: The 3205051 accepts 16-24 AWG, which is narrower than the 3050057 range of 12-26 AWG. Applications requiring termination of 12-14 AWG or 25-26 AWG conductors cannot use the substitute without design modification.

2. Termination style: The 3205051 provides IDC termination only, whereas the 3050057 offers both IDC and screw termination. Applications dependent on screw termination require alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3205051 directly replace the 3050057 in all applications?

A: Direct replacement is possible only when application requirements fall within the 16-24 AWG wire gauge range and IDC termination is acceptable. Applications requiring screw termination or wire gauges outside this range require alternative component selection.

Q: What is the significance of the wire gauge range difference?

A: The 3050057 accommodates wire gauges from 12-26 AWG, while the 3205051 is limited to 16-24 AWG. This difference affects which conductor sizes can be terminated. Verify that all conductors in your application fall within the 16-24 AWG specification before selecting the 3205051.

Q: Are the electrical ratings identical between these parts?

A: Yes. Both parts are rated for 17.5 A at 800V (IEC) and 10 A at 600V (UL). Electrical performance is equivalent.

Q: Why does the 3050057 show Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production. The 3205051, designated as the active substitute, is the recommended replacement for new designs and ongoing production requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the 3050057 and 3205051 are RoHS compliant and carry UL94 V-0 flammability certification.

Q: What is the difference in termination style, and does it matter?

A: The 3050057 offers both IDC (insulation displacement connector) and screw termination options. The 3205051 provides IDC termination only. If your application requires screw termination, the 3205051 is not suitable without design modification.
