Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2906831 is identified as a substitute based on the following criteria:

Substitution Logic: The 2906831 is a transient voltage suppressor module within the Phoenix Contact product ecosystem. While categorized differently (TVS vs. terminal block), it serves circuit protection functionality compatible with the 24VDC operating environment of the 2809649. The 2906831 operates at continuous voltages up to 21VDC with protection levels at 50V, aligning with the 24V UL rating of the main part.

Key Compatibility Parameters:

• Voltage compatibility: 24VDC operating range
• Manufacturer ecosystem: Phoenix Contact
• Mounting compatibility: DIN Rail mounting available
• Protection class: Active product status with current availability
• Regulatory compliance: UL and CSA certifications maintained

Parameter Comparison

Engineering Selection Recommendations

Selection between the 2809649 and 2906831 depends on application requirements:

2809649 (Obsolete): Suitable only for legacy system maintenance where exact form factor and 3-position feed-through configuration are mandatory. Inventory availability is limited (972 pcs), and no new production is expected.

2906831 (Active Substitute): Recommended for new designs and systems requiring circuit protection in 24VDC environments. Active product status ensures long-term availability (709 pcs in stock). Enhanced certifications (cCSAus, CSAus in addition to UL/CSA) provide broader regulatory coverage. ROHS3 compliance exceeds the RoHS requirement of the obsolete part.

Both parts maintain UL and CSA certifications, ensuring compatibility within North American regulatory frameworks. The 2906831's DIN Rail mounting and module-only form factor provide flexibility for panel-mount applications.

Frequently Asked Questions (FAQ)

Q: Can the 2906831 directly replace the 2809649 in existing installations?

A: Direct mechanical replacement is not possible due to different form factors (module vs. terminal block). However, the 2906831 provides equivalent circuit protection functionality for 24VDC systems. Application-specific integration assessment is required.

Q: What is the significance of the obsolete status of the 2809649?

A: Obsolete status indicates Phoenix Contact has discontinued production. The 972 pcs in current inventory represent the final available stock. For systems requiring this exact component, procurement should occur immediately. For new designs, the 2906831 is the recommended alternative.

Q: Are both parts suitable for the same voltage and current environments?

A: The 2809649 is rated for 30A at 24V UL. The 2906831 is a protection device rated for 21VDC continuous operation with 50V protection level. Both operate within the 24VDC environment, but serve different functional roles. The 2906831 provides transient suppression rather than terminal connection.

Q: What certifications apply to both parts?

A: Both parts carry UL and CSA certifications. The 2906831 additionally holds cCSAus and CSAus approvals, providing expanded regulatory recognition in Canadian markets.

Q: How do RoHS compliance levels differ?

A: The 2809649 meets RoHS Compliant standards. The 2906831 meets ROHS3 Compliant standards, representing a more recent and stringent compliance framework with expanded substance restrictions.
