Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2906846 is identified as a substitute component based on the following substitution criteria:

Primary Substitution Logic: The 2906846 is a Transient Voltage Suppressors (TVS) module designed to provide circuit protection functionality. While the main part (2788207) integrates surge arrestor protection within the terminal block assembly, the 2906846 provides equivalent transient voltage suppression through a dedicated protection module. Both components address the same functional requirement: protection against transient voltage events in electrical circuits.

Key Parameters Enabling Substitution:

• Both components are manufactured by Phoenix Contact
• Both are RoHS Compliant
• Both carry EAR99 ECCN classification
• Both are designed for circuit protection applications
• The 2906846 operates at continuous voltage levels (75VAC MCOV) suitable for low-voltage industrial applications
• DIN Rail mounting of the 2906846 provides integration compatibility with standard industrial control panel architectures

Functional Equivalence: The 2906846 delivers protection level specifications (1 kV VP at 2416 conditions) and discharge current capacity (5 kA nominal at 8/20µS) that align with the surge arrestor functionality embedded in the 2788207 terminal block.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 2788207 is classified as obsolete. The 2906846 maintains active product status with Phoenix Contact, ensuring ongoing availability, technical support, and compliance with current regulatory standards.

Compliance & Certification: Both components maintain RoHS Compliance and EAR99 ECCN classification. The 2906846 carries multi-agency approvals (cCSAus, CSA, CSAus, UL), providing broader regulatory acceptance across North American and international markets.

Functional Capability: The 2906846 is specified for continuous operating voltage of 75VAC (MCOV) with protection level of 1 kV and discharge current capacity of 5 kA. These specifications address transient voltage suppression requirements in low-voltage industrial control applications.

Integration Architecture: The 2906846 utilizes DIN Rail mounting, compatible with standard industrial control panel configurations. This differs from the screw termination approach of the 2788207, requiring evaluation of mechanical integration requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 2906846 directly replace the 2788207 in existing installations? A: The 2906846 provides equivalent transient voltage suppression functionality. However, the mounting method differs (DIN Rail versus screw termination), requiring mechanical integration assessment. The 2906846 is a dedicated protection module rather than an integrated terminal block assembly.

Q: What is the significance of the obsolete status of the 2788207? A: Obsolete classification indicates the 2788207 is no longer manufactured or supported by Phoenix Contact. The 2906846, with active product status, ensures continued availability and compliance with current manufacturing and regulatory standards.

Q: Are both components RoHS Compliant? A: Yes. Both the 2788207 and 2906846 are RoHS Compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What voltage levels are these components rated for? A: The 2788207 does not specify voltage ratings in the provided parameters. The 2906846 is rated for 75VAC continuous operating voltage (MCOV) with 1 kV protection level, suitable for low-voltage industrial applications.

Q: What are the temperature operating ranges? A: The 2788207 operating temperature range is not specified in the provided data. The 2906846 operates across -40°C to 85°C, covering standard industrial temperature requirements.

Q: How do the packaging and mounting approaches differ? A: The 2788207 uses screw termination for direct wire connection in a 4-position, 2-level configuration. The 2906846 is supplied as a module-only form factor with DIN Rail mounting, requiring panel-mounted installation infrastructure.
