Phoenix Contact 2834054 General Purpose Relay DPDT 24VAC - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2834054 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 10A at 24VAC coil voltage. This socketable relay features a lighted indicator and test button, designed for standard switching applications requiring dual-pole, dual-throw functionality. The product is currently obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component sourcing in legacy installations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834054 is determined by the following critical parameters that must remain consistent:

• Contact Configuration: DPDT (2 Form C) contact form is mandatory for functional equivalence
• Coil Voltage: 24VAC specification must be maintained for circuit compatibility
• Mounting Type: Socketable mounting ensures mechanical and electrical compatibility with existing sockets
• Termination Style: Plug-in termination is required for direct socket replacement
• Contact Material: Silver (Ag) contacts provide equivalent switching performance and reliability
• Switching Voltage Rating: 250VAC/250VDC maximum rating ensures safe operation in target applications

The substitute part Phoenix Contact 2903666 meets all critical substitution criteria. While the contact current rating increases from 10A to 12A, this represents an upward compatibility that does not compromise circuit function and provides enhanced current-handling capability for the same coil voltage and contact configuration.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903666 serves as a direct substitute for the obsolete 2834054 based on matching contact configuration (DPDT), coil voltage (24VAC), mounting type (socketable), and termination style (plug-in). The increased current rating of 12A versus 10A provides upward compatibility without introducing functional incompatibility.

Selection of the 2903666 is supported by its active product status, ensuring ongoing availability and supply chain continuity. Both parts maintain RoHS compliance, satisfying regulatory requirements for new installations and replacements in compliant systems.

Frequently Asked Questions (FAQ)

Q: Can the 2903666 be used as a direct replacement for the 2834054 in existing circuits?

A: Yes. Both relays share identical contact configuration (DPDT), coil voltage (24VAC), socketable mounting, and plug-in termination. The 2903666 is mechanically and electrically compatible with existing sockets and circuit designs. The higher current rating (12A vs. 10A) does not create incompatibility.

Q: What is the significance of the increased current rating in the substitute part?

A: The 2903666 is rated for 12A contact current compared to the 2834054's 10A rating. This represents upward compatibility—the substitute can safely handle the same or lower current loads as the original part without performance degradation.

Q: Are there any packaging or form factor differences between these parts?

A: Both parts are socketable relays with plug-in termination. No packaging or form factor differences exist that would prevent direct substitution in existing installations.

Q: Why is the 2834054 listed as obsolete?

A: The 2834054 has been discontinued by Phoenix Contact. The 2903666 represents the current-generation equivalent, ensuring access to compatible replacement stock for maintenance and repair applications.

Q: What compliance certifications apply to both parts?

A: Both the 2834054 and 2903666 are RoHS compliant, meeting environmental and regulatory requirements for electronic component use in regulated industries and applications.
