Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 3074004 is an obsolete component within the CLIPLINE UT series. Substitution is based on maintaining compatibility across the following critical parameters:

• Series Continuity: Both main and substitute parts belong to the CLIPLINE UT series, ensuring mechanical and electrical interface compatibility
• Termination Method: Screw termination is preserved in the substitute part
• Disconnect Configuration: Lever-actuated switch mechanism is maintained
• Isolation Type: Isolated configuration is retained
• Material and Flammability: Polyamide (PA) nylon construction with UL94 V-0 rating remains consistent
• Terminal Width: 6.2 mm terminal width is identical
• Stripping Length: 9 mm stripping length is unchanged
• Wire Gauge Compatibility: The substitute part supports 10-24 AWG, which encompasses the lower end of the original 10-26 AWG range, providing compatibility for most standard wire sizes

The substitute part 3214324 is an active product with enhanced electrical performance and regulatory compliance, making it suitable for applications previously served by the obsolete 3074004.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3214324 is the designated manufacturer-recommended substitute for the obsolete 3074004. Selection of this substitute is supported by the following engineering criteria:

• Product Status: The 3214324 is an active product with current manufacturing support, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: The substitute meets ROHS3 compliance and REACH requirements, exceeding the RoHS compliance of the original part and satisfying current environmental regulations
• Series Compatibility: Both components belong to the CLIPLINE UT series, maintaining mechanical and electrical interface consistency
• Electrical Performance: The substitute provides enhanced current capacity (36 A IEC versus 20 A IEC), offering improved performance headroom for applications
• Mechanical Compatibility: Identical terminal width (6.2 mm), stripping length (9 mm), and screw termination method ensure direct mechanical compatibility
• Material Consistency: Polyamide nylon construction with UL94 V-0 flammability rating is preserved, maintaining safety and thermal characteristics

The primary design difference is the increased number of positions (5 versus 3) and levels (3 versus 2) in the substitute part. Applications requiring exactly 3 positions should evaluate whether the 5-position configuration can be accommodated within the system design, or whether alternative 3-position active components within the CLIPLINE UT series are available.

Frequently Asked Questions (FAQ)

Q: Can the 3214324 directly replace the 3074004 in all applications?

A: The 3214324 is mechanically and electrically compatible with the 3074004 for screw termination, lever-actuated disconnect operation, and wire gauge handling. However, the substitute has 5 positions and 3 levels compared to the original 3 positions and 2 levels. Applications must accommodate this configuration difference or identify alternative 3-position components.

Q: What are the key differences in electrical ratings between these parts?

A: The 3214324 provides higher IEC current capacity (36 A versus 20 A) while maintaining the same IEC voltage rating (500V). The UL current rating remains 16 A for both parts, but the UL voltage rating differs (300V for the substitute versus 600V for the original). Applications operating at UL 600V must verify compatibility with the substitute's 300V UL rating.

Q: Are both parts RoHS compliant?

A: Yes. The 3074004 is RoHS Compliant, and the 3214324 is ROHS3 Compliant, which represents a more current regulatory standard. The 3214324 also meets REACH requirements.

Q: What wire gauges are supported by the substitute?

A: The 3214324 supports 10-24 AWG (0.14-6 mm²), which covers the standard wire sizes within the original 10-26 AWG range. Applications requiring 25-26 AWG wire must evaluate alternative components.

Q: Is the terminal width identical between the two parts?

A: Yes, both the 3074004 and 3214324 have a terminal width of 6.2 mm, ensuring mechanical compatibility with existing mounting and connection infrastructure.

Q: What is the stripping length for the 3214324?

A: The stripping length is 9 mm for both the original and substitute parts, maintaining consistency in wire preparation requirements.
