Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3050031 is based on the following critical parameters that must remain consistent:

• Number of Positions: 2 positions (fixed requirement)
• Number of Levels: 1 level (fixed requirement)
• Type: Ground, Earth connector (functional requirement)
• Terminal Width: 5.2 mm (mechanical compatibility)
• Material - Insulation: Polyamide (PA), Nylon (material specification)
• Material Flammability Rating: UL94 V-0 (safety compliance)
• Color: Green, Yellow (identification standard)
• Moisture Sensitivity Level: 1 (Unlimited) (environmental rating)

The substitute part Phoenix Contact 3050031 is identified as 3205035. This part maintains all critical mechanical and electrical parameters. The primary difference is the wire gauge range, which is narrower in the substitute (16-24 AWG versus 12-26 AWG), and the termination style is limited to IDC only in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3205035 is the designated substitute for the 3050031. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity. Both parts meet identical flammability and environmental compliance requirements (UL94 V-0, RoHS/ROHS3 Compliant, MSL 1).

Selection between these parts depends on application wire gauge requirements. The 3050031 accommodates the full range of 12-26 AWG, while the 3205035 is limited to 16-24 AWG. For applications requiring termination of 12-15 AWG or 25-26 AWG conductors, the 3050031 remains necessary. For applications within the 16-24 AWG range, the 3205035 provides an active alternative with equivalent mechanical and electrical performance.

The 3205035 offers screw termination capability only (IDC removed), which may impact installation methodology depending on application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 3205035 substitute for the 3050031 in all applications?

A: Substitution is valid only for applications using wire gauges within the 16-24 AWG range. Applications requiring 12-15 AWG or 25-26 AWG conductors must use the 3050031.

Q: What is the difference in termination style between these parts?

A: The 3050031 offers both IDC (Insulation Displacement Connector) and screw termination options. The 3205035 provides IDC termination only. Verify your application's termination methodology before substitution.

Q: Are the mechanical dimensions identical?

A: Yes. Both parts feature 5.2 mm terminal width, 2 positions, and 1 level configuration. Physical mounting compatibility is maintained.

Q: Do both parts meet the same safety and compliance standards?

A: Both parts are rated UL94 V-0 for flammability and carry MSL 1 (Unlimited) moisture sensitivity rating. The 3050031 is RoHS Compliant; the 3205035 is ROHS3 Compliant. Both meet applicable regulatory requirements.

Q: Why is the 3050031 marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this part number. The 3205035 represents the active product line continuation within the CLIPLINE series.

Q: Are the insulation materials the same?

A: Yes. Both parts use polyamide (PA) nylon insulation with identical UL94 V-0 flammability rating.
