Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2920641 is based on the following critical parameters:

Functional Equivalence Criteria:

• Surge protection capability for circuit protection applications
• DIN rail mounting compatibility
• Operating temperature range compatibility (-40°C minimum required)
• RoHS and regulatory compliance status
• Voltage and current handling specifications

The identified substitute, Phoenix Contact 2906713 (TTC-6-1X2-M-24DC-UT-I), operates as a transient voltage suppressor module within the same product family. While the 2906713 differs in form factor (base + module configuration versus integrated terminal block), it provides equivalent surge protection functionality for DIN rail-mounted applications and maintains compatibility with the electrical and environmental parameters of the original component.

Parameter Comparison

Engineering Selection Recommendations

Primary Consideration - Product Status: The 2920641 is classified as obsolete. The 2906713 maintains active product status with Phoenix Contact, ensuring continued availability, technical support, and compliance with current regulatory standards.

Compliance & Certifications: Both components carry EAR99 ECCN classification and share identical HTSUS coding (8536.30.8000), indicating equivalent trade classification. The 2906713 holds ROHS3 compliance, representing a more current regulatory standard than the RoHS compliance of the 2920641. The 2906713 includes broader approval agency certifications (ATEX, CCC, cCSAus, CSA, CSAus, cUL, EAC, UL), providing enhanced regulatory coverage for international applications.

Temperature Range Consideration: The 2920641 operates to 80°C maximum; the 2906713 operates to 70°C maximum. Applications requiring operation above 70°C require verification of thermal management or alternative solutions.

Form Factor Difference: The 2920641 is an integrated terminal block with surge protection. The 2906713 is a modular transient voltage suppressor (base + module configuration). System integration may require mechanical redesign to accommodate the different mounting profile.

Frequently Asked Questions (FAQ)

Q: Can the 2906713 directly replace the 2920641 in existing installations?

A: Direct mechanical replacement is not possible due to form factor differences. The 2920641 is an integrated terminal block, while the 2906713 is a modular TVS device. Electrical functionality for surge protection is equivalent, but installation requires system redesign to accommodate the base + module configuration.

Q: What is the significance of the 2906713 being classified as "Active" versus the 2920641 being "Obsolete"?

A: Active product status indicates ongoing manufacturing, technical support, and compliance with current regulatory requirements. Obsolete status means the component is no longer manufactured and may face supply constraints. Transitioning to the 2906713 ensures long-term component availability and support.

Q: Are there temperature limitations when substituting the 2906713 for the 2920641?

A: The 2906713 has a maximum operating temperature of 70°C, compared to 80°C for the 2920641. Applications requiring sustained operation above 70°C must evaluate thermal conditions or seek alternative solutions.

Q: Do both components meet the same regulatory standards?

A: Both components carry EAR99 classification and identical HTSUS coding. The 2906713 provides enhanced regulatory coverage with ROHS3 compliance and broader approval agency certifications (ATEX, CCC, cCSAus, CSA, CSAus, cUL, EAC, UL), making it suitable for a wider range of international applications.

Q: What is the voltage and current handling capability of the 2906713?

A: The 2906713 is rated for 21VAC or 30VDC continuous operating voltage (MCOV), with nominal discharge current of 5 kA and maximum discharge current of 20 kA at 8/20µS pulse duration. Protection level is 750V at 2416 test conditions.

Q: Is the 2906713 suitable for the same wire gauge applications as the 2920641?

A: The 2920641 accommodates 14-24 AWG (0.2-2.5mm²) wire gauges. The 2906713 specifications do not explicitly define wire gauge compatibility. Mechanical and electrical integration must be verified during system redesign.
