Substitute Part Grouping Explanation

The substitute part identified for the Phoenix Contact 2794686 is based on functional protection and circuit integration requirements. The primary substitution criterion is the presence of integrated transient voltage suppression (TVS) capability, which aligns with the diode feature specified in the main part.

Phoenix Contact part number 2906829 is classified as a Transient Voltage Suppressors (TVS) module within the TTC series. This substitute addresses applications requiring voltage protection at the connection point, matching the protective diode functionality of the original component.

Substitution logic is based on the following key parameters:

• Integrated protection feature (diode/TVS)
• Voltage rating compatibility (12V UL / 15VDC MCOV)
• Screw-based termination methodology
• RoHS and regulatory compliance alignment

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2906829 TVS module is an active product with current manufacturing status, providing an alternative to the obsolete 2794686 terminal block. Both components are manufactured by Phoenix Contact and maintain RoHS compliance.

The 2906829 offers enhanced regulatory approval coverage (cCSAus, CSA, UL certifications) and operates across a defined temperature range (-40°C to 85°C). The voltage protection level of 25V exceeds the 12V UL rating of the original component, providing margin for transient suppression applications.

Selection between these components should be based on specific application requirements: the 2794686 is suitable for direct feed-through terminal block applications, while the 2906829 addresses dedicated circuit protection requirements with DIN rail mounting methodology.

Frequently Asked Questions (FAQ)

Q: Can the 2906829 directly replace the 2794686 in existing installations?

A: Direct mechanical replacement is not feasible due to different mounting methodologies. The 2794686 uses screw termination for wire connection, while the 2906829 is a DIN rail-mounted module. Application redesign may be required.

Q: What is the primary functional difference between these components?

A: The 2794686 is a 2-position feed-through terminal block with integrated diode protection. The 2906829 is a dedicated transient voltage suppression module. The 2794686 provides primary connectivity with secondary protection, while the 2906829 provides primary protection functionality.

Q: Are both components RoHS compliant?

A: Yes. The 2794686 is RoHS Compliant, and the 2906829 is ROHS3 Compliant, meeting current regulatory requirements.

Q: What voltage ratings should be considered for substitution?

A: The 2794686 operates at 12V UL. The 2906829 provides 15VDC maximum continuous operating voltage (MCOV) with 25V protection level. The 2906829 rating provides compatibility with the original voltage specification.

Q: Is the 2906829 suitable for 10-26 AWG wire gauges?

A: The 2906829 is specified as a module-only form factor without explicit wire gauge parameters. Wire gauge compatibility depends on the terminal interface used in the complete assembly and must be verified against specific application requirements.
