Phoenix Contact 2795973 Terminal Block Connector - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2795973 is a 4-position disconnect terminal block connector rated for 12-24 AWG wire gauges (0.2-4mm²). This component features a knife-switch disconnect type with feed-through configuration and screw termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

The provided substitute part number 2906835 represents a different product category (Transient Voltage Suppressors - TVS) and does not constitute a functional equivalent for the Phoenix Contact 2795973 terminal block connector.

A valid substitute for the 2795973 must satisfy the following criteria based on allowed electrical and mechanical parameters:

• 4-position configuration with 2-level connectivity
• Disconnect or feed-through terminal block type
• Wire gauge compatibility: 12-24 AWG (0.2-4mm²)
• Screw termination method
• Polyamide or equivalent insulation material
• UL94 V-2 or superior flammability rating
• 6.2mm terminal width tolerance
• Black color specification
• RoHS compliance

The substitute part 2906835 does not meet these criteria, as it is classified as a circuit protection device (TVS module) with different electrical specifications (37VAC/53VDC MCOV, 80V protection level) and mounting configuration (DIN Rail), making it unsuitable as a direct replacement for terminal block applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2795973 is an obsolete terminal block connector. Sourcing decisions should be based on:

1. Product Status Consideration: The main part is obsolete. Active alternatives from Phoenix Contact within the TERMITRAB series or equivalent disconnect terminal block lines should be prioritized for new designs or long-term stock planning.

2. Compliance Verification: Any substitute must maintain RoHS compliance and UL94 V-2 flammability rating to ensure regulatory continuity in existing applications.

3. Functional Equivalence: Substitutes must preserve the 4-position, 2-level disconnect configuration with screw termination and 12-24 AWG wire gauge compatibility. Mounting method and terminal geometry must remain consistent with the original design.

4. Certification Alignment: The substitute part must carry equivalent agency approvals (UL, CSA, or equivalent) to maintain system certification status.

The listed substitute (2906835) is not functionally equivalent and should not be used as a replacement for the 2795973 in terminal block applications.

Frequently Asked Questions (FAQ)

Q: Why is the 2906835 listed as a substitute if it is not compatible?

A: The 2906835 is a transient voltage suppressor module, not a terminal block connector. This appears to be a data entry error or cross-reference mistake. It does not meet the functional requirements for substitution.

Q: What parameters must match for a valid substitute?

A: A valid substitute must match: number of positions (4), number of levels (2), disconnect type (knife switch, feed-through), wire gauge range (12-24 AWG / 0.2-4mm²), termination method (screw), insulation material (polyamide/nylon), flammability rating (UL94 V-2 minimum), and RoHS compliance status.

Q: Can I use a different wire gauge rating?

A: No. The 12-24 AWG specification is a critical parameter for safe current-carrying capacity and mechanical fit. Substitutes must support this exact range.

Q: Does the terminal width (6.2mm) need to match exactly?

A: Yes. Terminal width is a mechanical parameter that determines compatibility with mating connectors and PCB layouts. Substitutes must maintain this specification.

Q: What should I do since this part is obsolete?

A: Contact Phoenix Contact directly to identify active-status alternatives within the TERMITRAB series or equivalent product lines. Provide your application requirements (wire gauge, position count, voltage/current ratings) for proper recommendation.

Q: Is RoHS compliance mandatory for substitution?

A: Yes. The original part is RoHS compliant. Any substitute must maintain this compliance status to ensure regulatory continuity in your application.
