Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2903289 is determined by the following critical parameters:

• Coil Voltage: 230VAC (must match exactly for direct replacement without circuit modification)
• Mounting Type: DIN Rail (physical form factor requirement)
• Coil Current: 14 mA (power supply compatibility)
• Coil Type: Non Latching (functional behavior requirement)
• Termination Style: Screw Terminal (installation compatibility)
• Contact Material: Silver Nickel (AgNi) (electrical performance and reliability)
• Operating Temperature Range: -40°C to 40°C (environmental suitability)
• Switching Voltage: 440VAC, 250VDC Max (voltage withstand capability)

The primary distinction between the main part and substitute candidates is the Contact Form (DPDT vs. 3PDT) and Contact Rating (9A vs. 8A). These differences define the electrical capacity and switching capability of each relay variant within the RIF series.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2903285 is available as an active product with current manufacturing status, whereas the 2903289 is obsolete. Both relays share identical coil specifications (230VAC, 14 mA, non-latching), identical switching voltage ratings (440VAC, 250VDC Max), and identical timing characteristics (25 ms operate, 20 ms release).

The 2903285 provides enhanced compliance status with ROHS3 certification and REACH affected designation, compared to the RoHS Compliant status of the 2903289. Both parts maintain the same operating temperature range (-40°C to 40°C) and screw terminal termination.

Selection between these parts depends on circuit requirements: the 2903289 provides DPDT (2 Form C) switching with 9A contact rating, while the 2903285 provides 3PDT (3 Form C) switching with 8A contact rating. The contact form and current rating differences must be evaluated against specific application switching requirements.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2903285 directly replace the 2903289 in all applications?

A: Direct replacement is possible only if the application circuit accommodates the difference in contact form (3PDT vs. DPDT) and the reduced contact rating (8A vs. 9A). The 2903285 provides additional switching poles but lower current capacity per contact.

Q: Are the coil specifications identical between these relays?

A: Yes. Both relays operate on 230VAC coil voltage with 14 mA coil current, non-latching coil type, and identical timing characteristics (25 ms operate, 20 ms release). Power supply and control circuit compatibility is maintained.

Q: What is the significance of the product status difference?

A: The 2903289 is obsolete, indicating discontinued manufacturing. The 2903285 is active, ensuring ongoing availability and current manufacturing compliance standards. For new installations or long-term system support, the active product is preferred.

Q: Do both relays meet current compliance requirements?

A: The 2903285 meets ROHS3 and REACH compliance standards. The 2903289 meets RoHS Compliance. For applications requiring current regulatory compliance, the 2903285 is the appropriate selection.

Q: Are the switching voltage ratings equivalent?

A: Yes. Both relays are rated for 440VAC and 250VDC maximum switching voltage, providing identical voltage withstand capability across AC and DC applications.

Q: What is the packaging difference?

A: The 2903289 is packaged as individual units with socket included. The 2903285 is supplied in bulk packaging. Both include socket and varistor features.
