Phoenix Contact 2834494 General Purpose Relay DPDT 24VAC - Equivalent & Substitute Parts
Part Overview
The Phoenix Contact 2834494 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 8A at 24VAC coil voltage. This relay is designed for DIN rail mounting with screw terminal connections and includes integrated features such as a lighted indicator, socket inclusion, and varistor protection.
The 2834494 has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure continued availability for maintenance and replacement applications, and support long-term project sustainability where this relay type is specified.

Substitute Part Grouping Explanation
Substitution eligibility for the Phoenix Contact 2834494 is determined by strict equivalence across the following critical parameters:
- Contact configuration: DPDT (2 Form C) only
- Current rating: 8 A minimum
- Coil voltage: 24VAC
- Mounting: DIN rail compatible
- Termination: Screw terminal
- Contact material: Silver Nickel (AgNi)
- Relay classification: General purpose, non-latching
The Phoenix Contact 2903349 meets all substitution criteria. Both relays share identical contact form, current rating, coil voltage, mounting type, termination style, and contact material. Both are manufactured by Phoenix Contact and maintain compatibility with applications requiring these specifications.

Engineering Selection Recommendations
The Phoenix Contact 2903349 is the direct substitute for the obsolete 2834494. Both relays maintain functional equivalence across all critical electrical and mechanical parameters required for DPDT 8A 24VAC switching applications.
The 2903349 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The substitute meets enhanced RoHS3 compliance and is REACH affected, reflecting current regulatory standards. The 2903349 is available in bulk packaging, supporting production and inventory requirements.
Minor operational differences exist: the 2903349 exhibits a 6 ms longer release time (20 ms versus 14 ms) and operates across a wider temperature range (-40°C to 50°C versus -25°C to 60°C). These differences do not affect substitution eligibility for general purpose relay applications where DPDT switching at 8A and 24VAC coil voltage are specified.
Frequently Asked Questions (FAQ)
Q: Can the Phoenix Contact 2903349 directly replace the 2834494 in existing installations?
A: Yes. Both relays share identical contact form (DPDT), current rating (8A), coil voltage (24VAC), mounting type (DIN rail), termination style (screw terminal), and contact material (Silver Nickel). Electrical and mechanical compatibility is maintained.
Q: What is the primary reason for substitution?
A: The 2834494 has reached obsolete status. The 2903349 is an active product from the same manufacturer, ensuring continued availability for replacement and maintenance applications.
Q: Are there differences in operating characteristics between these relays?
A: The 2903349 has a release time of 20 ms compared to 14 ms for the 2834494. The 2903349 also operates across a wider temperature range (-40°C to 50°C versus -25°C to 60°C). These differences do not affect general purpose relay functionality where DPDT 8A 24VAC switching is required.
Q: What is the difference in coil current between these parts?
A: The 2834494 draws 26 mA, while the 2903349 draws 33 mA. This 7 mA difference is within acceptable tolerance for 24VAC coil applications and does not prevent substitution.
Q: Are both relays RoHS compliant?
A: Yes. The 2834494 is RoHS Compliant. The 2903349 is ROHS3 Compliant, reflecting current regulatory requirements. Both meet environmental compliance standards.
Q: What packaging options are available for the substitute part?
A: The 2903349 is supplied in bulk packaging, suitable for production orders and inventory management.
