Phoenix Contact 2794699 Terminal Block Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2794699 is a feed-through terminal block connector designed for 2-position applications with screw termination. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The terminal block accommodates wire gauges from 10-26 AWG (0.2-4mm²) and is rated for 30A at 24V UL specifications. Its polyamide construction with UL94 V-2 flammability rating and integrated diode feature support industrial control and power distribution applications.

Key Parameters

Substitute Part Grouping Explanation

The substitute part Phoenix Contact 2906831 is classified as a Transient Voltage Suppressors (TVS) module rather than a direct terminal block replacement. Substitution logic is based on the following criteria:

Allowable Substitution Parameters:

• Manufacturer alignment (Phoenix Contact)
• Voltage compatibility (24V operating range)
• Current handling capability (30A rated application)
• RoHS compliance status
• DIN Rail mounting compatibility for system integration
• Industrial control application suitability

Functional Distinction: The 2906831 operates as a circuit protection device (TVS module) with continuous operating voltage of 21VDC and protection level of 50V, whereas the 2794699 functions as a passive connection interface. These components serve different functional roles within a system architecture and should be evaluated based on system-level requirements rather than direct pin-for-pin equivalence.

Engineering Selection Recommendations

For Direct Terminal Block Replacement: The 2794699 is an obsolete feed-through terminal block. Direct functional equivalents should be sourced from current Phoenix Contact terminal block product lines within the TERMITRAB series or equivalent 2-position, screw-terminated offerings that maintain the 10-26 AWG wire gauge compatibility and 30A/24V electrical specifications.

For System-Level Circuit Protection Integration: The 2906831 TVS module addresses transient voltage suppression requirements in 24V DC systems and is suitable for applications requiring overvoltage protection. This component is active in production and carries current UL and CSA approvals. Selection of this component should be based on system architecture requirements for surge protection rather than as a direct terminal block substitute.

Compliance Considerations: Both components maintain RoHS compliance status. The 2906831 carries REACH Affected designation and broader approval agency certifications (cCSAus, CSA, UL), making it suitable for regulated industrial applications. The 2794699, as an obsolete component, should be replaced with current-production equivalents for new designs.

Frequently Asked Questions (FAQ)

Q: Can the 2906831 TVS module directly replace the 2794699 terminal block? A: No. The 2906831 is a circuit protection device, not a connection interface. These components serve different functional purposes. The 2794699 provides screw-terminated connection points, while the 2906831 provides transient voltage suppression on DIN Rail mounting. System architecture determines whether both components are required.

Q: What wire gauge compatibility should I verify when sourcing a replacement for the 2794699? A: Replacement terminal blocks must accommodate 10-26 AWG (0.2-4mm²) wire gauges with screw termination to maintain compatibility with existing wiring infrastructure.

Q: Are there voltage or current derating considerations when using the 2906831 in a 24V system? A: The 2906831 is rated for 21VDC continuous operating voltage (MCOV) with 50V protection level. System design must account for these specifications relative to actual operating conditions.

Q: What is the significance of the diode feature in the 2794699? A: The integrated diode provides polarity protection or reverse-current blocking functionality. Replacement terminal blocks should include equivalent protection features if this function is critical to system operation.

Q: How does the obsolete status of the 2794699 affect component sourcing? A: Obsolete components have limited availability and no ongoing manufacturer support. Current-production Phoenix Contact terminal block alternatives should be identified and qualified for new designs or long-term system maintenance planning.
