Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2906861 serves as a functional substitute based on the following alignment criteria:

Common Substitution Parameters:

• Manufacturer: Phoenix Contact (same manufacturer ensures design compatibility and support continuity)
• Surge Protection Function: Both components integrate transient voltage suppression capabilities
• RoHS Compliance: Both parts meet RoHS requirements
• ECCN Classification: Both classified as EAR99
• Operating Temperature Range: Compatible thermal specifications (-40°C ~ 85°C for substitute)

Substitution Logic: The 2906861 is a Transient Voltage Suppressors (TVS) module rated for 110VAC continuous operation with 800V protection level and 5kA discharge current (8/20µS). While the 2906861 represents a different product category (TVS module vs. terminal block), it provides equivalent surge protection functionality for applications requiring circuit protection in the specified voltage and current ranges. The DIN rail mounting compatibility and active product status of the 2906861 make it suitable for replacing the obsolete 2858205 in protection-critical applications.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The Phoenix Contact 2906861 is the designated substitute for the obsolete 2858205. Selection of the 2906861 is based on:

1. Manufacturer Continuity: Both components are Phoenix Contact products, ensuring design philosophy alignment and technical support availability
2. Active Product Status: The 2906861 maintains active production status, guaranteeing long-term availability and supply chain stability
3. Compliance Alignment: Both parts maintain RoHS compliance and identical ECCN classification (EAR99), ensuring regulatory compatibility
4. Surge Protection Equivalence: The 2906861 provides transient voltage suppression functionality equivalent to the gas-filled surge arrestor in the 2858205
5. Thermal Compatibility: The specified operating temperature range (-40°C ~ 85°C) for the 2906861 covers standard industrial applications

Application Considerations: The 2906861 is suitable for applications requiring circuit protection in 110VAC systems with protection levels up to 800V and discharge currents up to 5kA. Integration into existing DIN rail-mounted systems is supported through standard mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Why is the 2858205 being discontinued? A: The 2858205 is classified as obsolete by Phoenix Contact. The 2906861 represents the current-generation equivalent providing enhanced surge protection capabilities with active production support.

Q: Can the 2906861 directly replace the 2858205 in all applications? A: The 2906861 provides equivalent surge protection functionality. However, application-specific requirements regarding terminal block configuration (4-position, 2-level) and push-in spring termination must be evaluated independently. The 2906861 is a TVS module, not a terminal block connector, and may require circuit redesign for optimal integration.

Q: What are the key electrical differences between these parts? A: The 2858205 features integrated gas-filled surge arrestor protection with unspecified voltage and current ratings. The 2906861 is a dedicated TVS module with specified 800V protection level and 5kA discharge current (8/20µS), providing measurable and standardized protection characteristics.

Q: Are both parts RoHS compliant? A: Yes. Both the 2858205 and 2906861 are RoHS compliant and classified as EAR99 for export control purposes.

Q: What is the operating temperature range for these components? A: The 2906861 operates across -40°C to 85°C. Operating temperature specifications for the 2858205 are not provided in the technical data.

Q: How does packaging affect substitution? A: The 2858205 is supplied in standard packaging, while the 2906861 is supplied in bulk packaging. Procurement quantities and handling procedures may differ accordingly.

Q: What inventory status should influence purchasing decisions? A: The 2858205 has 719 units in stock (obsolete status), while the 2906861 has 936 units in stock (active status). For new designs and long-term applications, the 2906861 is recommended due to its active product status and assured future availability.
