Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2906838 is identified as a substitute component. Substitution logic is based on the following criteria:

Shared Electrical Parameters:

• Manufacturer: Phoenix Contact
• Voltage compatibility: Both rated for DC voltage operation (2794916 at 48V UL; 2906838 at 60VDC maximum continuous operating voltage)
• Circuit protection function: Both incorporate transient voltage suppression or varistor-based protection
• RoHS and REACH compliance: Both meet environmental regulatory requirements

Functional Relationship: The 2906838 operates as a transient voltage suppressor module designed to protect circuits from voltage transients. While the 2794916 integrates varistor protection within a terminal block form factor, the 2906838 provides dedicated circuit protection suitable for DIN rail mounting in the same voltage and current protection range.

Compatibility Constraints:

• Form factor differs: 2794916 is a screw-terminal block; 2906838 is a DIN rail-mounted module
• Application context determines suitability: Direct mechanical substitution is not possible; functional substitution requires system redesign

Parameter Comparison

Engineering Selection Recommendations

For Direct Mechanical Replacement: No direct mechanical substitute exists within the provided data. The 2794916 is a screw-terminal feed-through block; the 2906838 is a DIN rail-mounted protection module. These components serve different mechanical interfaces and cannot be directly swapped in existing installations.

For Functional Circuit Protection: The 2906838 provides equivalent transient voltage suppression capability within the same voltage and current protection envelope. Selection of the 2906838 requires system redesign to accommodate DIN rail mounting and module-based integration rather than screw-terminal integration.

Compliance Considerations: Both components maintain RoHS and REACH compliance. The 2906838 carries CSA and UL approvals, meeting the same regulatory framework as the 2794916. The 2906838's active product status ensures continued availability and technical support, addressing the obsolescence constraint of the 2794916.

Frequently Asked Questions (FAQ)

Q: Can the 2906838 directly replace the 2794916 in an existing installation?

A: No. The 2794916 uses screw-terminal connection; the 2906838 requires DIN rail mounting. Direct mechanical substitution is not possible without system redesign.

Q: Are the voltage ratings compatible between these parts?

A: Yes, within the specified operating range. The 2794916 is rated 48V UL; the 2906838 is rated 60VDC maximum continuous operating voltage. The 2906838 can protect circuits designed for the 2794916's voltage specification.

Q: What is the primary reason to consider the 2906838 as a substitute?

A: The 2794916 is obsolete. The 2906838 is an active Phoenix Contact product offering equivalent transient voltage suppression functionality and regulatory compliance, ensuring long-term component availability.

Q: Do both parts meet the same environmental and regulatory standards?

A: Both components are RoHS and REACH compliant. The 2906838 carries CSA and UL approvals, meeting industrial safety standards equivalent to the 2794916.

Q: What packaging differences exist between these components?

A: The 2794916 is supplied in standard packaging; the 2906838 is supplied in bulk packaging. Packaging format does not affect electrical or functional compatibility.
