Phoenix Contact 2834698 General Purpose Relay DPDT 24VAC - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 2834698 is a general purpose relay with DPDT (2 Form C) contact configuration, designed for 24VAC coil operation on DIN rail mounting. This relay provides 10A contact rating at switching voltages up to 250VAC and 125VDC maximum. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and replacement applications.

Substitute Part Grouping Explanation
Substitution of the Phoenix Contact 2834698 is determined by the following critical parameters:
- Coil Voltage: 24VAC (must match exactly for direct replacement)
- Contact Form: DPDT (2 Form C) configuration (functional requirement for switching logic)
- Mounting Type: DIN Rail (physical form factor requirement)
- Termination Style: Spring Terminal (connection interface requirement)
- Coil Type: Non Latching (operational behavior requirement)
- Contact Material: Silver or Silver Nickel alloys (acceptable for general purpose switching)
The Phoenix Contact 2903313 qualifies as a substitute based on matching all critical parameters. While the 2903313 has a reduced contact rating of 8.5A compared to the original 10A specification, it maintains functional equivalence for applications within its current rating limits.

Engineering Selection Recommendations
The Phoenix Contact 2903313 is the identified substitute for the obsolete 2834698. Both components are RoHS compliant and manufactured by Phoenix Contact with identical coil voltage, contact form, mounting type, and termination style specifications.
Selection of the 2903313 requires evaluation of application current requirements. The substitute part has a maximum contact rating of 8.5A, which is 1.5A lower than the original specification. Applications operating at or below 8.5A continuous current are suitable for direct substitution. Applications requiring the full 10A rating of the original part must be reassessed for alternative solutions.
The 2903313 operates across a wider temperature range (-40°C to 50°C versus -25°C to 60°C) and provides enhanced DC switching capability (250VDC maximum versus 125VDC maximum). Coil current consumption increases from 46mA to 70mA, and switching response times are slightly longer (15ms operate, 20ms release versus 10ms operate, 12ms release).
Frequently Asked Questions (FAQ)
Q: Can the Phoenix Contact 2903313 directly replace the 2834698 in all applications?
A: Direct replacement is possible only in applications where the load current does not exceed 8.5A. The substitute part has a lower contact rating than the original. Applications requiring the full 10A specification require alternative component selection.
Q: What are the key differences between these two relays?
A: The primary differences are contact rating (10A versus 8.5A), coil current consumption (46mA versus 70mA), switching response times (10ms/12ms versus 15ms/20ms operate/release), and operating temperature range (-25°C to 60°C versus -40°C to 50°C). Both maintain identical coil voltage, contact form, mounting type, and termination style.
Q: Are both relays RoHS compliant?
A: Yes, both the 2834698 and 2903313 are RoHS compliant components.
Q: What is the significance of the contact material difference (Silver versus Silver Nickel)?
A: Both Silver (Ag) and Silver Nickel (AgNi) contact materials are acceptable for general purpose relay applications. Silver Nickel provides enhanced durability and wear resistance in switching applications.
Q: Does the 2903313 support the same switching voltages as the original?
A: The 2903313 supports 250VAC and 250VDC maximum switching voltages, compared to 250VAC and 125VDC for the original. This represents improved DC switching capability in the substitute part.
Q: What packaging is available for the substitute part?
A: The Phoenix Contact 2903313 is available in bulk packaging.
