Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 3101139 is determined by strict equivalence across the following critical parameters:

• Manufacturer and series consistency (Phoenix Contact CLIPLINE UDMTK)
• Identical connector type and disconnect mechanism (Dual Disconnect, Switch Knife)
• Matching position and level configuration (3 positions, 2 levels)
• Equivalent electrical ratings (8A current, 400V IEC voltage)
• Compatible wire gauge acceptance (12-26 AWG / 0.2-4mm²)
• Identical termination method (Screw)
• Matching terminal geometry (6.2mm width)
• Equivalent material and flammability specifications (Polyamide PA, UL94 V-2)

The substitute part 3101126 meets all these criteria and differs only in color designation (Gray vs. Blue), which does not affect electrical or mechanical function.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3101126 is the direct equivalent substitute for the obsolete 3101139. Both components are RoHS compliant and carry identical UL94 V-2 flammability certification. The 3101126 maintains active product status, ensuring continued availability and supply chain reliability. The sole difference—color designation—carries no functional impact on electrical performance, mechanical compatibility, or regulatory compliance. Selection of the 3101126 is appropriate for applications requiring the electrical and mechanical specifications of the 3101139.

Frequently Asked Questions (FAQ)

Q: Can the 3101126 be used as a direct replacement for the 3101139? A: Yes. Both parts share identical electrical ratings (8A, 400V IEC), mechanical configuration (3 positions, 2 levels, 6.2mm terminal width), termination method (screw), wire gauge acceptance (12-26 AWG), and material specifications (Polyamide PA, UL94 V-2). The color difference does not affect functionality.

Q: What is the significance of the product status difference? A: The 3101139 is marked obsolete, indicating discontinued manufacturing. The 3101126 maintains active status, confirming current production and supply availability. This makes the 3101126 the recommended choice for new designs and ongoing maintenance.

Q: Are there any packaging differences between these parts? A: The 3101139 is supplied with unspecified packaging, while the 3101126 is supplied in bulk packaging. Both configurations contain the same functional component.

Q: Do both parts meet the same compliance standards? A: Yes. Both the 3101139 and 3101126 are RoHS compliant and carry UL94 V-2 flammability certification. Both are classified under ECCN EAR99 and HTSUS 8536.69.8000.

Q: Can color be a selection criterion for these parts? A: Color is a visual identifier only and does not affect electrical or mechanical performance. Selection should be based on functional requirements and availability. The 3101126 (gray) is functionally equivalent to the 3101139 (blue).
