Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2834591 is determined by the following critical parameters:

• Mounting Type: DIN Rail (mechanical compatibility)
• Contact Form: DPDT (2 Form C) (functional equivalence)
• Coil Voltage: 230VAC (electrical compatibility)
• Contact Rating: 8 A minimum (load capacity)
• Switching Voltage: 250VAC, 250VDC maximum (voltage withstand)
• Termination Style: Spring Terminal (connection compatibility)
• Contact Material: Silver Nickel (AgNi) (contact performance)

The Phoenix Contact 2903331 meets all substitution criteria within the allowed parameter ranges for this product category.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903331 is a direct functional substitute for the obsolete 2834591. Both relays share identical electrical specifications for coil voltage (230VAC), contact configuration (DPDT), current rating (8A), and switching voltage (250VAC/250VDC). The 2903331 is currently in active production status with higher inventory availability (1068 pcs vs. 628 pcs), ensuring supply chain continuity.

The 2903331 meets enhanced compliance requirements (ROHS3 Compliant and REACH Affected) compared to the main part's RoHS Compliance. The substitute features an integrated varistor for improved transient protection. Operating temperature range differs slightly (-40°C to 50°C vs. -25°C to 60°C), with the substitute providing lower temperature capability. Coil current is marginally higher (6 mA vs. 5.5 mA) and release time is slightly faster (20 ms vs. 22 ms), both within acceptable engineering tolerances for general purpose relay applications.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903331 directly replace the 2834591 in existing installations?

A: Yes. Both relays share identical contact form (DPDT), coil voltage (230VAC), current rating (8A), switching voltage (250VAC/250VDC), and termination style (Spring Terminal). DIN rail mounting is identical. Physical dimensions and socket compatibility require verification against your specific installation, but electrical substitution is valid.

Q: What is the difference in operating temperature range between these parts?

A: The 2834591 operates from -25°C to 60°C, while the 2903331 operates from -40°C to 50°C. The substitute provides extended low-temperature capability but reduced high-temperature capability. Select based on your application's thermal environment.

Q: Why is the 2903331 listed as having a varistor when the 2834591 does not?

A: The varistor in the 2903331 provides transient voltage suppression on the coil circuit, improving protection against voltage spikes. This is an enhancement in the substitute design and does not affect substitution compatibility.

Q: Are there packaging differences between these parts?

A: The 2834591 is packaged as individual units with socket included. The 2903331 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to each part?

A: The 2834591 is RoHS Compliant. The 2903331 is ROHS3 Compliant and REACH Affected. Both carry EAR99 ECCN classification and 8536.49.0050 HTSUS code. Confirm compliance requirements for your end application and market.
