Phoenix Contact 2794709 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2794709 is a feed-through terminal block connector designed for 2-position applications with screw termination. It accommodates wire gauges from 10-26 AWG (0.2-4mm²) and is rated for 30A at 48V UL. The unit features a diode and is constructed from polyamide (PA) nylon material with UL94 V-2 flammability rating. This part carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new designs requiring similar connectivity solutions.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 2906832 is identified based on manufacturer continuity within Phoenix Contact's product portfolio. However, critical functional differences exist that require engineering evaluation:

Substitution Logic Parameters:

• Manufacturer alignment (Phoenix Contact)
• Voltage compatibility range (48V nominal operation)
• RoHS and regulatory compliance status
• Operating temperature range overlap

Key Limitation: Part 2906832 is categorized as a Transient Voltage Suppressor (TVS) module, not a terminal block connector. This represents a functional category change rather than a direct electrical substitute. The TVS module is designed for circuit protection applications on DIN rail mounting, whereas the 2794709 is a screw-terminal feed-through connector for direct wire termination.

Parameter Comparison

Engineering Selection Recommendations

For Direct Connector Replacement: Part 2906832 is not suitable as a direct electrical substitute for the 2794709. The 2794709 functions as a passive feed-through terminal block with screw termination for wire connections. The 2906832 is an active circuit protection device requiring DIN rail installation and is intended for transient voltage suppression, not wire termination.

For System Continuity: If the 2794709 is required for replacement in an existing system, Phoenix Contact's current terminal block portfolio should be consulted for active-status 2-position feed-through connectors with equivalent screw termination, wire gauge compatibility (10-26 AWG), and 48V rating.

Compliance Basis: Both parts maintain RoHS compliance and UL agency approvals, supporting use in regulated environments. The 2906832's active product status and ROHS3 compliance provide advantages for new designs, but functional compatibility must be independently verified against circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2906832 directly replace the 2794709 in an existing application? A: No. The 2906832 is a transient voltage suppressor module designed for DIN rail mounting and circuit protection. The 2794709 is a screw-terminal feed-through connector for direct wire termination. These serve different functional roles and cannot be substituted without circuit redesign.

Q: What makes the 2794709 obsolete, and why is the 2906832 listed as a substitute? A: The 2794709 carries obsolete status, indicating Phoenix Contact has discontinued this model. The 2906832 is listed as a related part within Phoenix Contact's portfolio, but this reflects manufacturer association rather than functional equivalence. Direct replacement requires identifying an active-status terminal block with matching specifications.

Q: Are both parts suitable for 48V applications? A: Yes, both parts support 48V operation. The 2794709 is rated at 48V UL, while the 2906832 operates at 53VDC MCOV with 80V protection level. However, voltage compatibility alone does not establish functional substitution.

Q: What are the key parameters that determine substitution eligibility? A: For terminal block substitutes, critical parameters include: number of positions (2), termination style (screw), wire gauge range (10-26 AWG / 0.2-4mm²), current rating (30A), voltage rating (48V), mounting type (direct screw terminal), and insulation material (polyamide/nylon). The 2906832 does not match the mounting and termination requirements.

Q: Are there compliance or certification advantages to using the 2906832? A: The 2906832 holds active product status and ROHS3 compliance, compared to the 2794709's obsolete status and RoHS compliance. However, compliance advantage does not override functional incompatibility. A suitable replacement must meet both compliance and functional requirements.
