Phoenix Contact 2834672 General Purpose Relay DPDT 230VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834672 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 230VAC coil voltage. This relay is designed for DIN rail mounting and includes a lighted indicator, socket, and varistor protection. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and replacement applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834672 is determined by the following critical parameters:

• Coil Voltage: 230VAC (must match exactly for direct replacement)
• Contact Form: DPDT (2 Form C) (functional requirement for switching configuration)
• Mounting Type: DIN Rail (physical form factor requirement)
• Termination Style: Screw Terminal (connection interface requirement)
• Coil Type: Non Latching (operational characteristic)

The Phoenix Contact 2903321 qualifies as a substitute part because it maintains the same coil voltage (230VAC), contact form (DPDT), mounting type (DIN Rail), termination style (Screw Terminal), and coil type (Non Latching). While certain performance parameters differ, these differences fall within acceptable tolerance ranges for general purpose relay applications.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903321 is an active product substitute for the obsolete 2834672. Both relays share identical coil voltage (230VAC), contact configuration (DPDT), mounting interface (DIN Rail), and termination method (Screw Terminal). The 2903321 carries ROHS3 compliance, providing enhanced regulatory alignment compared to the RoHS Compliant status of the original part.

The 2903321 exhibits a lower contact current rating (8.5A versus 10A) and increased coil current draw (6.5mA versus 4mA). Operate and release times are extended (15ms and 20ms respectively, compared to 10ms and 12ms). The contact material differs from silver to silver nickel. These parameter variations must be evaluated against specific application requirements to determine suitability for replacement.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903321 directly replace the 2834672 in all applications?

A: Direct replacement is possible only when the application tolerates the parameter differences. The 2903321 has a lower current rating (8.5A versus 10A), longer switching times, and different contact material. Applications requiring the full 10A rating or faster switching response may not be compatible.

Q: What are the key compatibility criteria for substitution?

A: The substitute part must maintain 230VAC coil voltage, DPDT contact configuration, DIN Rail mounting, Screw Terminal termination, and Non Latching coil type. The 2903321 meets all these criteria.

Q: Does the contact material change from Silver to Silver Nickel affect performance?

A: Contact material composition is provided in the specifications. Application-specific requirements determine whether this material change is acceptable.

Q: What is the significance of the product status difference?

A: The 2834672 is obsolete, making the active 2903321 the appropriate substitute for new procurement and system maintenance.

Q: Are there packaging differences between these parts?

A: The 2834672 is listed with "-" packaging designation, while the 2903321 is supplied in Bulk packaging.

Q: How do the operating temperature ranges compare?

A: The 2834672 operates from -25°C to 60°C, while the 2903321 operates from -40°C to 50°C. Application temperature requirements must be verified against these ranges.
