Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2834737 is determined by strict equivalence across the following critical parameters:

• Contact configuration: 4PDT (4 Form C)
• Contact current rating: 5 A minimum
• Coil voltage: 24VAC
• Mounting type: DIN Rail
• Termination style: Screw Terminal
• Relay type: General Purpose, Non Latching
• Maximum switching voltage: 250VAC, 250VDC or higher

The substitute part Phoenix Contact 2903318 meets all these criteria. Both relays share identical contact form, current rating, coil voltage, mounting configuration, and termination method. Variations in coil current, operate/release times, and operating temperature range do not prevent functional substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903318 is the direct substitute for the obsolete 2834737. Both parts are manufactured by Phoenix Contact and maintain identical electrical and mechanical specifications for the primary switching function.

The 2903318 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The part carries ROHS3 compliance, meeting current regulatory requirements. The 2903318 is available in bulk packaging, supporting production and inventory requirements.

Selection of the 2903318 is appropriate for applications requiring 4PDT relay functionality at 5A, 24VAC coil voltage with DIN rail mounting and screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903318 directly replace the 2834737 in existing installations?

A: Yes. Both relays share identical contact configuration (4PDT), current rating (5A), coil voltage (24VAC), mounting type (DIN Rail), and termination style (Screw Terminal). The 2903318 is a direct functional equivalent.

Q: What are the differences between these two relays?

A: The 2903318 has higher coil current (66 mA vs. 46 mA), longer operate and release times (15 ms and 20 ms vs. 10 ms and 12 ms), and a narrower operating temperature range (-40°C to 50°C vs. -25°C to 60°C). The 2903318 uses Silver Nickel contact material only, while the 2834737 includes Gold plating. The 2903318 has lower coil resistance (364 Ohms vs. 522 Ohms).

Q: Are there packaging differences?

A: The 2834737 packaging is listed as dash (standard), while the 2903318 is supplied in bulk packaging. Both are suitable for DIN rail installation.

Q: Does the higher coil current of the 2903318 affect circuit design?

A: The coil current difference (46 mA to 66 mA) must be evaluated within the context of the control circuit design. The control circuit must supply sufficient current to operate the 2903318 coil reliably.

Q: Are both parts RoHS compliant?

A: Yes. The 2834737 is RoHS Compliant. The 2903318 is ROHS3 Compliant, meeting current regulatory standards.
